You can use Duck.ai, Perplexity, Google Gemini, Grok, Brave Leo and Opera AI for free without creating an account. Each vendor says so on its own help pages, terms or product pages, which we checked on November 5, 2026. If you only want ChatGPT without signing up, that works too. On October 23, 2026, OpenAI's help center said ChatGPT "can be used without an account in supported countries", with one conversation at a time and no saved history.
The usual trade-off: no account means no history across devices, and often fewer uploads, lighter models or tighter daily limits. The bigger difference is privacy. Some services promise not to store or train on logged-out chats, and one says the opposite. The table below sorts that out.
How we checked "no sign-up"
A service made this list only if the vendor's own page says it can be used without an account or without signing in. We did not count third-party "no login" lists, browser tests from one country, or services that let you type a question but ask for an account before showing the answer.
Several popular assistants did not qualify, because we found no vendor page confirming logged-out use:
- Claude, Anthropic's assistant. Its help center says the free version is available by signing up with an email address.
- Microsoft Copilot. Its terms of use, effective August 18, 2026, say you must have a Microsoft Account to use Copilot.
- Meta AI, Meta's assistant.
- Mistral's Vibe, which Mistral's help center says is the new name for Le Chat.
- DeepSeek and HuggingChat.
Their free plans may still suit you once you sign up. For a broader list that includes services with accounts, see our programmatic page of ChatGPT alternatives.
Compare the no-login options (as of November 2026)
Free AI chatbots you can use without an account
| Service | Where it runs | No-login use confirmed by | Saved history without an account | Vendor says logged-out chats train models |
|---|---|---|---|---|
| Duck.ai | duck.ai in any browser | DuckDuckGo blog and help pages | ✓ stored on your device | No |
| Perplexity | perplexity.ai in a browser | Perplexity help center | ✓ for 14 days | Not stated |
| Gemini | gemini.google.com in a browser | Gemini Apps Help | No | Not stated |
| Grok | grok.com, where available | Grok terms of service | ✗ (consumer FAQ, October 23, 2026) | Yes |
| Brave Leo | Brave browser only | Brave's Leo page | ✓ stored on your device | No |
| Opera AI | Opera browser only | Opera's AI feature page | Not stated | Not stated |
What each one asks you to sign in for:
- Perplexity: Pro Search, uploading files and saving sessions. A free account adds five Pro Searches a day and three file uploads, per Perplexity's help center.
- Gemini: Google says you can use "some features" of the web app without signing in, and you need a Google Account "to use additional features or save your Gemini Apps activity", per Gemini Apps Help.
- Grok: as of October 23, 2026, the consumer FAQ said people who do not register and log in "will not have their data retained for their use after the session".
- ChatGPT: one conversation at a time, kept only for the current browser session, per OpenAI's help center as of October 23, 2026.
Duck.ai: the most private web option
Duck.ai is DuckDuckGo's chat service. DuckDuckGo's announcement says it is "free to use, with no account required", and its help pages say there is a daily usage limit that it enforces without tracking you.
As of November 2026, the free version offers Claude Haiku 5.5, Mistral Small 4, GPT-6 Luna, GPT-5.4 mini, gpt-oss-120b and Gemma 4 31B. DuckDuckGo says it does not store your prompts or train on your data, and your recent chats are saved on your device, not on its servers. You can also create images, within a daily limit.
Pros
- No account, and chats are stored only on your device
- Several model families in one place
- Two models run in a sealed environment where even the host cannot see prompts
Cons
- The free models are the lighter ones; stronger models such as Claude Sonnet 5.5 and GPT-5.6 Terra need a DuckDuckGo subscription
- Daily limit, and a VPN or mobile network can trigger limit errors
Perplexity and Gemini without an account
These are the big-company options. Each works in a browser without an account, with fewer features until you sign in.
Perplexity is the pick when you need sources, because it shows the pages behind its answers. Logged-out threads stay visible for 14 days before they expire. Sign in only when you need file uploads or Pro Search.
Gemini opens at gemini.google.com without a Google sign-in for some features. It is the quickest way to try Google's assistant, but anything you want to keep needs an account. For what the free and paid Gemini plans add, see our ChatGPT vs Claude vs Gemini comparison.
Grok works logged out, but read the training terms
Grok's terms of service, last updated October 27, 2026, allow use without logging in "where available". The same sentence goes on: where permitted, you then grant SpaceXSI (SpaceX Super Intelligence), the company behind Grok, "full rights to use any data you provide" for product development and model training.
Grok's consumer FAQ, as of October 23, 2026, added that logged-out content may be kept on an anonymous basis. In some regions, excluding the EU and UK, it said you could not opt out of model training when using Grok without logging in. If you want Grok and care about training, sign in and use the opt-out setting, which the terms describe for logged-in users. You can find Grok in our directory as Grok by xAI.
Brave Leo and Opera AI: assistants built into the browser
If you are willing to switch browsers, two of them ship an assistant that needs no account.
Brave Leo lives in the Brave browser on desktop and mobile. Brave's Leo page says "no account or signup is required to access the free Brave Leo experience", that Leo does not retain or share chats or use them for model training, and that chat history can be stored locally on your device. It can read the page you are on, which is handy for summaries. Brave says Leo may be less available at busy times; Premium raises the limits.
Opera AI, formerly Aria, is built into the Opera browser. Opera's Android announcement says it "is free, requires no account", and Opera's feature page lists models from OpenAI and Google and free image generation.
AI assistant for seamless web browsing and information retrieval.
A browser designed for a customizable and engaging online experience.
Run a model on your own computer instead
The most private option involves no chat service at all. With a local app, the model runs on your laptop or desktop and your prompts never leave it.
Ollama is the simplest to start. Its quickstart says to sign in only to use cloud models, "or choose a local model", and its FAQ says "we don't see your prompts or data when you run locally". The catch is hardware: small models run on most recent laptops, larger ones need a strong GPU or an Apple Silicon Mac with plenty of memory. Our guide to running an LLM locally walks through setup, and how much VRAM you need helps you pick a model that fits.
- Install Ollama from its website.
- Pick a small open-weight model that fits your memory.
- Chat in the terminal or in the app. No internet connection is needed once the model is downloaded.
Pick the right one for your task
Which no-login chatbot to try first
| You want to... | Try |
|---|---|
| Ask quick questions with the least tracking | Duck.ai |
| Research a topic with cited sources | Perplexity |
| Use a big-company assistant for free | Gemini |
| Summarize the page you are reading | Brave Leo |
| Keep everything on your own machine | Ollama |
| Use ChatGPT itself, just once | ChatGPT logged out |
Two rules apply to all of them. Do not paste passwords, customer data or anything confidential into a chatbot you cannot control; our guide on whether it is safe to put company data into ChatGPT and other assistants explains why. And check facts in any answer, because free tiers usually run the lighter models. To find more free tools by task, try the AI Tool Finder.
