Free AI chatbots like ChatGPT October 2026
Limits, sign-up, images, files and age rules, read on the pages of 19 AI chatbots. All but HuggingChat are free to start, but they differ on privacy and on who may use them.
Checked by hand on 16 October 2026, on each company’s own pages.2 of 80 have moved since, re-checked 22h ago.
The short answer
If you read nothing else, read this.
- Most free use: ChatGPT gives unlimited everyday text chats, and Perplexity practically unlimited basic searches. Gemini and Claude reset your limit every 5 hours. Most others give no numbers.
- No sign-up: Duck.ai, Brave Leo and Lumo need no account. ChatGPT, Gemini, Grok, Perplexity, Kimi and Arena let you start without one, with fewer features. Copilot now needs a Microsoft account, under its terms of 18 August 2026.
- Free images: ChatGPT, Gemini, Copilot, Meta AI, Mistral Vibe, Qwen, Duck.ai and Lumo make pictures on free, but none says how many. Claude and Pi make no images at all.
- Read your files: most take PDFs or photos on free, though Gemini, Grok and Perplexity want you signed in first. Duck.ai reads PDFs up to 15 pages, and Kimi takes files up to 100 MB each. Pi takes no images.
- Web search: all the big names search the web on free, and Perplexity is built around it, with citations. Duck.ai, Poe, HuggingChat, Pi and Character.AI do not say they search.
- Age limits: Claude, Qwen, Pi and Arena are for adults only, 18+. DeepSeek, Kimi and Duck.ai are meant for adults but let under-18s in with a parent. Most others start at 13. Character.AI gives under-18s a teen version with no open-ended chat.
- Students: Gemini works with a school Google account from age 13. Verified students pay less for Mistral Pro ($5.99 a month) and Perplexity Education Pro ($10). Free months of ChatGPT Plus and Google AI Pro for US college students are in our ChatGPT Plus trial guide.

Free runs on GPT-5.6 Luna. Without an account nothing is saved, and that is not yet offered in Europe, except the UK. Ads may appear on Free and Go in some countries. OpenAI may train on free chats; you can turn this off in settings, even without an account. One older OpenAI help line says uploads need a paid plan; the pricing page says free gets some.
In their own words(4, checked 5 Oct)
“Free users have unlimited everyday text chats, subject to abuse-prevention safeguards. File uploads, image generation, voice, data analysis, and other tools have separate usage limits.”
“ChatGPT is free to use, and can now be accessed before creating an account at chatgpt.com.”
“You must be at least 13 years old or the minimum age required in your country to consent to use the Services. If you are under 18, you must have your parent or legal guardian’s permission to use the Services and ask them to read these Terms with you.”

How many messages you get changes with demand. You need a phone number from a supported country that can get texts. Free gets the Sonnet and Haiku models, not Opus. Claude can draw charts with code, but makes no pictures. Anthropic may train on your chats unless you opt out in settings.
In their own words(4, checked 5 Oct)
“While using the free Claude plan, there is a session-based usage limit that will reset every five hours.”
“You must have a phone number that can receive a verification code via text message to create and use a Claude account.”
“Claude doesn’t generate photos or illustrations the way image-generation tools do.”

“Higher usage than free for AI image creation in Copilot”
“To use Copilot you must have a Microsoft Account, and you need to be old enough at least 13, but sometimes older, depending on your country’s laws.”

Its privacy policy says your data is stored in China, and its search sends your keywords to other search services. To keep your chats out of training, turn off "Improve the model for everyone". DeepSeek sells its models to developers, but the chat has no paid plan, and it has retired the download page that used to say so.
In their own words(4, checked 7 Oct)
“The prices listed below are in units of per 1M tokens.”
“Before using the Services, you shall register an account using your Email or third-party account as per the page instructions.”

How much is free depends on where you live. Signed out, outside the EU and UK, you cannot opt out of training. Signed in, turn off "Improve the Model" in Settings, or use Private Chat. xAI's own pages disagree on whether free users can make images: its pricing page lists limited image making on free, but its help page names only chat and voice. SuperGrok is no longer on the pricing page.

Answers come with citations. Sign in for Pro Search, file uploads and saved history. Its own pages disagree on free Pro Searches (3 or 5 a day) and on whether free users can make images. Free searches can train Perplexity's AI: turn off "AI data retention" in settings. In India, web plans are billed in US dollars.

Le Chat was renamed Vibe on 12 August 2026: same app at chat.mistral.ai, same login. Pro gives up to 6 times more messages and 40 times more images than Free. Free chats train Mistral's models unless you turn this off in settings, and Temporary Chat is never used. The student price needs a school email, lasts up to 12 months, and is only for students who have not used Vibe or Le Chat before.
In their own words(4, checked 5 Oct)
“Yes, Mistral’s Free plan provides limited access to Vibe, including our latest models, chat, search, creation, and Vibe for code for agentic coding in your terminal.”

The chat app at chat.qwen.ai, once Qwen Chat, is now just called Qwen. No page says how much is free, or what you can do without an account. It is for private, non-commercial use only. To keep your chats out of training, you must email Qwen.
In their own words(4, checked 5 Oct)
“It’s free to use, open to all, and ready to help with creativity, collaboration, and endless possibilities.”
“Ask Qwen to create images and videos using a simple prompt or detailed paragraph.”
“By uploading structured or unstructured data files, such as CSV, Excel, or text documents, Qwen can automate data analysis, generate concise summaries, and create insightful visualizations.”
“You must be at least 18 years old or meet the minimum age required to consent to using this Service in your location, whichever is greater.”
Free with no account, and private
These three need no account at all, and each says it does not use your chats to train AI. ChatGPT, Gemini, Grok, Perplexity, Kimi and Arena also let you start without one.

DuckDuckGo says your chats do not train AI, its own or the model makers'. Bigger models use the daily limit faster, and only some take uploads. A VPN or mobile data can make you hit the limit early. The paid plan is sold only in the US, Canada, the EU and the UK.

“Duck.ai is free to use, but there is a daily limit on usage.”
“Both Duck.ai and Search Assist are free to use and anonymized by us, with no account required.”

Proton says Lumo keeps no chat logs and does not train AI on your chats. Guest chats are erased when the session ends. A free Proton account gives more prompts, keeps chats for 7 days, and may be needed to upload files. Past the daily limit on the Max model, Lumo switches to Lite. Its price table loads by script, so its prices are not here.
In their own words(4, checked 5 Oct)
“You can also instantly start a chat with limited access without an account at lumo.proton.me”
“Yes. Lumo's free plan has a limited number of Max model usage, messages, chat history, image generations, Projects, and Custom Lumos.”
“Lumo's free plan includes essential features that support your productivity, like basic chat history, web search, and the ability to upload individual small files”

Character.AI calls itself an entertainment platform for stories and role play with AI characters. Free has banner ads, and a waiting room when the site is busy. Under 18 you get a teen version with no open-ended chat. Extra images cost Charms, which you earn free in the app. Your chats can train its models; it gives steps to stop this only in the EEA and UK.

“YES! We are proud to continue offering free and unlimited messaging for ALL users”
“To create an account, you can sign up on the web or mobile using an email address and birthday.”

In Battle Mode two unnamed models answer, you vote, then you see their names. For text and code, battles do not use your daily credits. A free account lets you pick a model, such as Claude Opus 4.6, Gemini 3 Pro or GPT-5.2. Arena shares your chats with the AI companies whose models answer and may publish them in research datasets, so never type anything personal.
In their own words(4, checked 5 Oct)
“Arena's usage system gives users a daily balance of usage credits that can be used for free.”
“While you can explore Arena without logging in, signing up provides several benefits:”
“Access to features that require user login. Such as Direct mode, Side by Side mode, Image Arena, and Video Arena.”
“The Service is not intended for use by anyone under 18 years of age.”

Poe puts bots from many AI companies in one app. Each message costs points, and each bot shows its price, so how far they go depends on the bot. Logged out, poe.com shows only ways to sign in. Official bots do not train on your chats; other developers' bots may. Poe does not say if $4.99 needs a yearly plan, and it does not sell plans in Pakistan.
In their own words(4, checked 5 Oct)
“Non-paying users receive points daily, which reset at the end of each 24-hour period. Points do not roll over.”
“Cutting-edge image generators like those from FLUX, Ideogram, etc.”
“Subscribers receive a higher number of points than non-paying users receive. They also gain access to the most cutting-edge bots on Poe.”
“Poe offers access to all major models and more starting at $4.99/month.”

Every model and feature spends the same credits, and a deep research report takes about 5 to 10% of the free pool. Kimi does not say how often free credits refill. Prices here are from kimi.ai in US dollars; kimi.com shows other plans in Chinese yuan. Your chats can train its models unless you email Kimi to opt out.
In their own words(4, checked 5 Oct)

Questions
What is the best free AI chatbot like ChatGPT?
If you want ChatGPT itself, its free plan has unlimited everyday text chats, plus limited images and uploads. Gemini, Copilot and Meta AI also make images, read files and search the web for free, without saying how much. For no account at all, try Duck.ai. For answers with sources, try Perplexity.
Which free AI chatbot works without signing up?
Duck.ai, Brave Leo (inside the Brave browser) and Lumo need no account. ChatGPT, Gemini, Grok, Perplexity, Kimi and Arena let you start without one, with fewer features: ChatGPT gives one chat at a time and saves nothing (not yet in most of Europe), and Gemini gives text chat only. Microsoft Copilot now needs a Microsoft account, and Claude, Meta AI, DeepSeek, Character.AI and HuggingChat need an account too.
Which free AI chatbot can make images?
ChatGPT, Gemini, Copilot, Meta AI, Mistral Vibe, Qwen, Duck.ai and Lumo make images on free, and none says how many. Gemini needs you signed in for it, and Qwen also makes videos. Claude and Pi make no images. Grok's and Perplexity's own pages disagree on whether free users can.
Which free AI chatbots can students under 18 use?
ChatGPT, Gemini, Copilot, Meta AI, Grok, Perplexity, Mistral and Lumo start at 13, some with a parent's OK until 18. Gemini also works with a school Google account. DeepSeek, Kimi and Duck.ai are meant for adults but allow under-18s with a parent. Claude, Qwen, Pi and Arena are 18+ only, and Character.AI gives under-18s a teen version with no open-ended chat.
Is DeepSeek free?
Yes. DeepSeek's chat is free and has no paid plan: DeepSeek sells its models to developers instead. It publishes no free limits. You need an account (email, Google or Apple). Its privacy policy says your data is stored in China, and you can turn off "Improve the model for everyone" to keep your chats out of training.
Which free AI chatbot keeps my chats private?
Duck.ai, Brave Leo and Lumo say they do not use your chats to train AI, and none of them needs an account. Most others may use free chats for training, and many let you turn this off in settings. On Arena, chats go to the AI companies whose models answer and may be published in research datasets, so keep anything personal out.
