Khám Phá Các Trang Web Đối Thoại AI: Hướng Dẫn Của Bạn Về Các Chatbot Miễn Phí Và Không Bị Kiểm Duyệt

Hầu hết các trang về AI chat không bị hạn chế đều hoặc là thổi phồng những ảo tưởng jailbreak hoặc giả vờ rằng mọi chatbot đều giống nhau. Cả hai đều không hữu ích khi bạn đang cố gắng tìm ra nơi bạn có thể nói chuyện tự do hơn, nơi nào vẫn có những bức tường cứng, và liệu một công cụ được gọi là không bị kiểm duyệt có đáng tin cậy với thời gian hoặc dữ liệu của bạn hay không.

Dưới đây là phiên bản ngắn sau khi kiểm tra các trang sản phẩm hiện tại, tài liệu trợ giúp và các trang chính sách từ các nhà cung cấp lớn. tính đến ngày 12 tháng 4 năm 2026: không có chatbot công cộng chính thống nào hoàn toàn không bị hạn chế, và những cái mà tự quảng cáo như vậy thường có nghĩa là một trong ba điều. Chúng hoặc là áp dụng ít rào cản rõ ràng hơn, cho phép bạn sử dụng các mô hình trọng số mở với sự kiểm duyệt nhẹ hơn, hoặc đẩy trách nhiệm trở lại cho bạn bằng cách giữ nhiều phần của hệ thống ở chế độ cục bộ và riêng tư.

Sự phân biệt đó rất quan trọng. Nếu bạn chỉ muốn một trợ lý ít đạo đức hơn cho tiểu thuyết, nhập vai, brainstorming táo bạo, hoặc thử nghiệm prompt đối kháng, một sản phẩm được lưu trữ như Venice hoặc Duck.ai có thể cảm thấy đủ mở. Nếu bạn muốn kiểm soát thực sự về hành vi từ chối, prompt hệ thống, giữ lại, và lựa chọn mô hình, điều gần nhất với AI chat không bị hạn chế vẫn là một thiết lập cục bộ thông qua các công cụ như LM Studio hoặc Ollama. Nếu những gì bạn thực sự cần là một trợ lý hàng ngày đáng tin cậy, câu trả lời chính thống tốt nhất vẫn là một trong những sản phẩm có rào cản, và bạn sẽ tốt hơn khi so sánh giá trị thô giữa các chatbot AI miễn phí tốt nhất vào năm 2026 thay vì theo đuổi một ứng dụng không quy tắc ma thuật mà thực sự không tồn tại.

I am going to keep this practical. You will see which tools are genuinely more open, which ones only look open during the first five prompts, what the current free tiers and paid tiers look like in USD, and where privacy gets better or worse once you start chasing fewer filters. I will also show where “unrestricted” stops being a feature and starts becoming a liability.

Why “AI Chat Unrestricted” Means Different Things and Still Has Hard Limits

People use the phrase AI chat unrestricted as if it points to one clean category. It does not. In practice, the phrase usually hides three different goals, and if you mix them together you end up testing the wrong products.

The first bucket is what most searchers actually mean. They are not trying to remove every legal or safety boundary on earth. They just want a chatbot that stops refusing harmless adult fiction, aggressive satire, politically charged debates, character roleplay, darker worldbuilding, or red-team style prompt experiments every other minute.

The second bucket is about convenience. A lot of “unrestricted” traffic is really people asking for no sign up, no phone verification, no card, no waitlist, and no personal profile just to ask a weird question or test a persona. Those users are often better served by anonymous chat products than by an “uncensored” app specifically. That is why many readers who start here also end up looking for safer free chat options that still feel more open once they see the tradeoffs.

The third bucket is the only one that gets you close to real freedom. If you download a model and run it locally, there is no central consumer chat service deciding what your session history looks like, how many prompts you get today, or whether your account gets rate limited because too many people showed up. That does not make the model wise, accurate, or legally consequence-free. It just means you control more of the environment.

Here is the test I use. If a company hosts the chat, owns the account system, publishes safety rules, and can revoke access, it is not fully unrestricted. It may still be useful. It may even be much looser than ChatGPT. But it is still a governed service. If you keep that mental model straight, the rest of the market gets much easier to read.

Before comparing products, you need one blunt reality check: every major mainstream assistant still enforces hard safety boundaries in 2026. OpenAI’s published usage policies continue to prohibit harmful activity, illegal exploitation, abuse, weaponization, and attempts to circumvent safeguards. Google’s Gemini app policy guidelines still say the product should avoid child sexual abuse material, dangerous activities, and other outputs tied to real-world harm. Anthropic’s public help and product positioning remain firmly in the “helpful but bounded” camp rather than the “say anything” camp.

That means if your definition of unrestricted is “give me detailed instructions for malware, fraud, doxxing, weapons, self-harm, sexual exploitation, or evading platform safeguards,” you are not comparing consumer chat products anymore. You are looking for either a bad-faith workaround or a self-hosted open model that pushes risk entirely onto you. I am not going to pretend there is a clean mainstream shortcut there, because there is not.

The more interesting question is what public chat tools sẽ let you do now. In April 2026 the better hosted bots are much more flexible with adult fiction, creative conflict, sharp rhetorical debate, edgy humor, darker roleplay, persuasion practice, jailbreak research framed as analysis, and system-prompt experiments that stay inside legal and safety boundaries. In other words, the fight is less about whether AI can be candid and more about where each product starts acting like an overprotective compliance intern.

That is why low-filter products keep attracting attention. Not because the big vendors are useless, but because people notice the difference between “I cannot help with that” and “I can discuss this topic, but I will not cross specific lines.” One feels like a brick wall. The other feels like an adult conversation.

So when you hear “unrestricted,” read it as relative, not absolute. The real spectrum looks more like this:

• Mainstream guarded assistants: highest quality, strongest policies, best productivity defaults.
• Hosted low-filter assistants: looser tone, fewer false-positive refusals, still bound by provider rules and business risk.
• Open-model demos: uneven quality, sometimes much looser, sometimes fragile and inconsistent.
• Local open-model setups: most control, highest responsibility, least hand-holding.

If you keep expecting category one to behave like category four, every comparison will feel dishonest. The useful move is picking the category that matches your actual tolerance for setup work, privacy risk, and unpredictability.

Best AI Chat Unrestricted Options You Can Actually Use Right Now

The table below reflects live product positioning and publicly listed pricing or free-tier details that were available tính đến ngày 12 tháng 4 năm 2026. I am ranking practical fit for “less filtered or more controllable” use, not raw benchmark prestige.

If you want one sentence per tool, here it is. Venice is the best hosted answer when “unrestricted” means fewer filter interruptions. Duck.ai is the cleanest anonymous answer when privacy and low friction matter more than raw power. Local setups are the only serious answer when you want actual control rather than looser branding. DeepAI is usable for disposable prompts but not where I would start if quality matters. The mainstream names are still better assistants overall, but they are not where I send people who are specifically frustrated by repeated false-positive refusals.

Another pattern worth noticing: products that feel more open usually give up something else. Sometimes that is polish. Sometimes it is long-session consistency. Sometimes it is file tooling, research depth, or trust that the platform will still behave the same way next month. That is why a lot of people who try “uncensored” tools for novelty end up keeping a guarded mainstream assistant open in the next tab anyway.

If your goal is simply getting the most usable free AI before the paywall gets annoying, not necessarily the loosest moderation, the comparison gets different fast. That broader value question belongs in a general free-chatbot comparison, not in an unrestricted-only checklist like this one.

Hosted Low-Filter AI Tools That Feel More Open Than ChatGPT

This is the slice of the market most people care about. They do not want to build a local stack tonight. They want a browser tab that is less uptight than ChatGPT, preferably cheap or free, and preferably not tied to a heavy onboarding flow.

Venice is the clearest hosted “fewer filters” play right now

Venice is blunt about its positioning. Its current pricing and product pages call the platform private, uncensored, and built for “unrestricted intelligence.” The free plan is a real sampler rather than a fake button: base AI models, 10 text prompts per day, 15 image prompts per day, and a clear upgrade path to Pro at $18 per month. Pro adds unlimited text prompts with Free and Pro models, up to 1,000 images per day on eligible models, character creation, encrypted chat backup, and monthly credits for premium models, video, music, or API use.

Why people like it is obvious after ten minutes: Venice is less likely to derail a harmless but spicy prompt with a lecture. It is much more comfortable with adult tone, speculative characters, controversial framing, and creative freedom that mainstream assistants often over-police. For fiction writers, roleplay users, and prompt tinkerers, that difference feels immediate.

The catch is that Venice is still a hosted product with business logic, pricing logic, and platform logic. “Uncensored” in marketing does not mean immune from legal constraints, abuse controls, or product changes. The $0 tier is also just that: a sampler. If you start using it as your primary daily chat, you hit the wall fast.

Duck.ai is a better answer if your real complaint is friction plus privacy

Duck.ai is more interesting than a lot of roundup posts admit. DuckDuckGo’s current help pages say the free version gives you anonymized access to multiple third-party chat models with no account required. As of April 2026, DuckDuckGo lists Claude 4.5 Haiku, Llama 4 Scout, Mistral Small 3 24B, GPT-4o mini, and GPT-5 mini among the free choices, with more advanced models reserved for subscribers.

The detail that matters most for this keyword is DuckDuckGo’s moderation note: it says Duck.ai does not filter or modify responses from the model itself. That sounds like the holy grail until you read the next sentence: Anthropic, Meta, Mistral, and OpenAI still apply their own moderation policies behind the scenes. So Duck.ai is not magically provider-free. What it does do is remove one extra layer of nannying while keeping the session anonymous and relatively clean.

That makes Duck.ai the best fit for quick idea checks, controversial but legal discussion, and throwaway testing when you do not want to create another AI account just to see how a different model responds. It is not the right tool if you need deep file work, long project memory, or a truly custom environment.

DeepAI and open-model fronts are fine for disposable experiments

DeepAI still has a place because the free version exists without much friction, and the paid tier is only $9.99 per month. The official pricing page says free users get limited access to basic features while Pro unlocks smarter chat and more advanced tools. That makes it a decent low-stakes option when you want to test a prompt without opening your main account elsewhere.

I would still frame it honestly: DeepAI is not where I go when I want the best writing, the sharpest reasoning, or dependable long-session work. It is where I go when I want a fast disposable second opinion. The same goes for many public open-model chat fronts. They can be fun, sometimes surprisingly loose, and occasionally excellent on a good day. They can also drift, forget context, or collapse under load.

If that kind of freer, more playful interaction is what you are after, keep expectations anchored. You are trading polish for freedom. That trade can be absolutely worth it. It just needs to be a conscious trade.

Local AI Setups That Give You the Most Control Over Moderation

If you want the closest thing to unrestricted AI chat without relying on a platform’s mood, local is the direction that actually changes the equation. Not because local models are magically smarter or more ethical, but because they move control from the vendor back to your machine.

Two tools dominate the beginner-friendly side of that workflow in 2026: LM Studio và Ollama. LM Studio’s own site positions it as a local AI toolkit that lets you discover, download, and run models on your computer, chat with them, run a local server, and work with documents. Ollama’s quickstart docs make the same core promise in a more terminal-friendly way: install Ollama on macOS, Windows, or Linux, run a model locally, and talk to it through a simple local interface or API.

This is the part most people miss when they search unrestricted AI chat. The moderation you experience is not only a property of the app. It is also a property of the model you choose, the system prompt you apply, the tools you attach, and whether the runtime phones home to a central service. Once you control those layers, the conversation changes completely.

My basic local setup advice is simple:

1. Start with one easy runtime. LM Studio is smoother if you want a visual app. Ollama is smoother if you like terminal workflows and APIs.
2. Pick one sane open model first. Do not begin with the biggest thing you can find. Start with a reputable 7B to 14B class model that actually runs well on your hardware.
3. Test refusal style before testing extremes. Ask for edgy but legal creative writing, argumentative roleplay, and style transfer first. That tells you more than jumping straight to shock prompts.
4. Keep sensitive work local on purpose. The privacy gain only matters if you are not piping everything back into a cloud tool two steps later.
5. Separate experimentation from deployment. A local model you enjoy for private brainstorming is not automatically ready for public users, clients, or customers.

The biggest strength of local chat is control over refusal behavior and data location. The biggest weakness is that you lose the invisible safety net that good hosted products provide. If your model hallucinates, rambles, gets mean, or follows a bad prompt too eagerly, there is no trust-and-safety team stepping in. That is your problem now.

For builders, that is usually a fair trade. For casual users, it depends on how much setup pain they are willing to absorb. If you want a practical way to test multi-turn behavior, character consistency, and prompt steering before you ever wire something into production, our hướng dẫn mô phỏng trò chuyện AI is the closest cluster companion to this local-first mindset.

What ChatGPT, Claude, Gemini, Copilot, and Perplexity Still Block

It is tempting to talk about unrestricted AI as if the mainstream tools are useless by comparison. That is the wrong read. The guarded tools are often better products. They are just solving for safety, stability, and broad public usability instead of maximum expressive latitude.

ChatGPT is still the default tab for a reason. OpenAI’s current pricing pages position the free plan as a real feature set, not just a teaser: limited access to GPT-5, web search, limited file uploads, limited image and voice tools, projects, and custom GPT use. That is serious value. It just is not unrestricted value. Logged-out use is even tighter. OpenAI’s help documentation says you can try ChatGPT before creating an account in supported countries, but you only get one conversation at a time, saved chats require login, and logged-out chats are governed by their own data controls.

Claude is the tool I still trust most when the output has to sound clean, mature, and deliberate. Anthropic’s pricing page keeps the free plan broad enough to matter: web, mobile, and desktop chat, writing and editing help, text and image analysis, and web search. The constraint is just more visible. Anthropic’s help center says free Claude usage is session-based and resets every five hours. That cadence is fine if you work in bursts and annoying if you try to live in it all day.

Song Tử is more generous on breadth than people give it credit for. Google’s US subscriptions page now lists free access with Gemini 3 Flash, varying access to 3.1 Pro, image generation and editing, Deep Research, Gemini Live, Canvas, Gems, and 50 daily AI credits tied to certain creation features. The catch is that Google’s signed-out help pages are also very clear: no past chats, no connected Google services, no image generation, no Gems, and no file uploads when you stay signed out. That is a meaningful split.

Copilot deserves its own lane because Microsoft has made the free tier unusually easy to open. Microsoft’s support docs say sign-in is not required for basic use, while signing in unlocks history, image creation, longer conversations, voice interactions, and other Copilot features. That means Copilot is excellent as a casual, grounded fallback and weak as an answer to unrestricted chat. It is about convenience more than expressive freedom.

Perplexity remains the research specialist. Its current help docs say a free account includes five Pro Searches per day, three file uploads, Collections, Threads, and Discover, while signed-out users can only use some features. If your question needs sources, Perplexity is better than most low-filter tools. If your question needs weird character play or unguarded creative drift, it is the wrong product.

The pattern across all five tools is consistent. They outperform looser tools on reliability, multimodal breadth, search grounding, and day-to-day work. They underperform looser tools when your prompts live in the gray zone between harmless adult creativity and what a trust team worries might look risky at scale.

How to Stress-Test an Unrestricted AI Chat Without Getting Burned

The fastest way to waste time with this category is to ask one spicy question, get one spicy answer, and decide the tool is perfect. That tells you almost nothing. A real test checks consistency, privacy, escalation behavior, and whether the platform gets flaky the moment you move from novelty to actual use.

I also recommend one sanity rule: never use a low-filter or supposedly unrestricted bot first on a sensitive real task. Do not begin with private contracts, customer data, medical details, or confidential strategy notes. Start with disposable prompts. If the tool proves stable, then graduate carefully.

Roleplay users should go even further. Test persona memory, consent language, refusal tone, and whether the bot slips into manipulative or creepy behavior when the scene changes. A chatbot that is fun for three exchanges and weirdly unstable for thirty is not a good roleplay tool. If character depth is your main filter, the better benchmark is our roleplay chatbot breakdown, because character play and unrestricted policy tolerance overlap only partially.

One more thing: the most dangerous “uncensored” bots are often the ones that feel the most flattering. If the model is always eager, always compliant, never cautious, and always emotionally sticky, that can create a false sense of trust. A useful open-feeling assistant should still be predictable. Reckless obedience is not intelligence. It is just a different failure mode.

Where Privacy Breaks First When You Chase Fewer Filters

People often assume freer chat means more private chat. Sometimes it does. Sometimes the opposite is true. This is where a lot of users make bad tradeoffs because they focus on censorship and ignore storage, account state, and provider routing.

Duck.ai is the strongest privacy story in the hosted group. DuckDuckGo’s help pages say chats are anonymized, not used to train AI models, and recent chats can stay local on your device. It also says metadata like your IP address is stripped before prompts hit model providers, and providers must delete data once no longer needed, at most within 30 days in most cases. That is a real privacy architecture, not just a vibe.

Venice is strong on the privacy claim too. Its docs say it does not store or log prompts or model responses on its servers and forwards requests over encrypted paths to decentralized providers. If that architecture holds for your use case, it is a serious differentiator.

The mainstream guest modes are a different story. OpenAI’s logged-out ChatGPT experience is handy, but it is a convenience mode first, not an invisibility cloak. Google’s signed-out Gemini mode is transparent about the fact that some usage and technical data may still be collected even when you are not logged in, and it strips away advanced features rather than offering a fully private full-power mode.

The cleanest rule I can give you is this: if the reason you want unrestricted AI chat is that you plan to discuss sensitive work, skip the flashy hosted “uncensored” marketing and go local instead. If the reason is just convenience and creative freedom, a hosted option can be fine, but only if you treat it like a public cloud tool and act accordingly.

When Unrestricted AI Chat Is Useful and When It Becomes a Liability

Less-filtered AI is genuinely useful in more cases than critics admit. It is good for fiction that needs antagonists to sound like antagonists. It is good for satire, debate rehearsal, game writing, NPC prototyping, villain monologues, and research into how models frame taboo or controversial ideas. It is also useful for red-teaming prompts that are safe in context but often get smothered by overbroad moderation.

That is the productive side of the keyword. If your definition of unrestricted is “let me explore weird but legal creative territory without being treated like a criminal,” then yes, this category has real value. It is also why playful users often end up mixing these tools with character-focused experiences and voice-first experiments like the ones covered in our guide on how to chat with AI online for voice, text, and character play.

The liability shows up the second you move from private experimentation into public or high-stakes use. A low-filter chatbot is the wrong default for:

• Hỗ trợ khách hàng: You do not want freeform guesses on refunds, compliance, or billing.
• Communities with minors: The moderation burden becomes non-negotiable fast.
• Medical, legal, or financial guidance: Freedom here is not a feature. It is exposure.
• Brand channels: One reckless answer can become the screenshot that defines your week.
• Security or abuse-adjacent prompts: Even harmless research needs strict separation from production systems.

I also would not confuse “more open” with “more truthful.” Some of the loosest bots are more willing to hallucinate because they are less eager to self-check. They feel honest because they do not scold you. That does not mean they are more accurate. A polished refusal can be annoying. A fluent wrong answer can be expensive.

So use low-filter chat where exploration is the point. Use guardrailed chat where reliability is the point. Use local chat where control is the point. Most frustration in this space comes from asking one category to do another category’s job.

How to Build a Safe Messenger or Website Bot Without Making It Feel Censored

If your end goal is a customer-facing bot, chasing unrestricted AI is usually the wrong design brief. What you want is a bot that feels conversational, flexible, and non-robotic without exposing your business to hallucinations, abuse, or policy chaos.

The better architecture is layered:

1. Use fixed answers for high-risk topics. Pricing, refunds, shipping, compliance, account actions, and legal claims should not be improvised.
2. Use generative AI for low-risk language work. Tone adaptation, summarization, follow-up questions, and soft lead qualification are good places for it.
3. Give the bot a clean handoff path. “Let me send this to a human” is not a failure. It is what protects the rest of the system.
4. Log prompts and edge cases internally. If users keep hitting the same confusing zone, that is a design problem you can fix.
5. Test with real message history. Not synthetic demos. Your actual customer questions are where the weak spots appear.

This is how you avoid the false choice between “boring FAQ bot” and “wild unrestricted bot.” A good business chatbot feels open because it understands intent, not because it has no brakes. In practice, users do not reward you for letting the bot say anything. They reward you for getting the answer right, quickly, in a tone that does not feel canned.

The easiest mistake is importing a low-filter assistant directly into a public messaging flow because it felt fun in testing. Private experimentation and public automation are not the same environment. When a user is angry, confused, or asking about money, the model needs structure more than freedom.

That is especially true on Messenger and other social channels where screenshots travel faster than context. The right workflow is usually: freer sandbox internally, tighter rules publicly, human escalation when needed. That gives your team flexibility without forcing your customers to absorb the model’s worst days.
