Talk to it the way you'd talk to a person
You don't need special commands. Describe what you want, add the details that matter, and keep going with follow-up questions until the answer fits.
- Paste long texts, notes or code straight into the message box.
- Ask it to shorten, rewrite, translate or explain its own answer.
- Start a new chat for a new topic — earlier chats stay in your sidebar.
I have 20 minutes and eggs, spinach, feta and some old bread. What can I make for two?
A quick spinach and feta strata works well. Tear the bread into a greased dish, wilt the spinach in a pan, then whisk 4 eggs with a splash of milk. Pour it over the bread and spinach, crumble the feta on top and bake at 200 °C for about 15 minutes, until set. Want a stovetop version instead?
Yes, no oven please.

Your chats stay on your device
Conversation history is kept in your browser's local storage, not in a user profile on our server.
Works in your language
Write in any language and the answer comes back in the same one. The site itself is available in 18 languages.
Clear, fair limits
To keep it free for everyone, each connection has a daily message allowance. You'll see a plain message when you reach it.
What happens when you press send
Your message and the recent part of the conversation go to the model, which writes the reply word by word. Nothing is stored in an account, because there isn't one.

Common questions
Is this ChatGPT really free?
Yes. You can chat without paying or creating an account. A daily allowance per connection keeps the service sustainable; when it runs out, it resets within 24 hours.
Is chagpt.org the official ChatGPT website?
No. chagpt.org is an independent site and is not run by OpenAI. The chat sends your messages to OpenAI's GPT-6 Luna model through the OpenRouter API. The official product is at chatgpt.com.
Which model answers my questions?
GPT-6 Luna, released by OpenAI in September 2026. It is the fastest, lowest-cost model in the GPT-6 family and handles everyday writing, explaining and coding well.
Are my conversations saved?
Your chat history is saved only in your own browser so you can come back to it. We do not keep conversation logs tied to you. Avoid sharing passwords or sensitive personal data in any AI chat.
Can it make mistakes?
Yes. Like every language model, it can state wrong facts with confidence. Check anything important — numbers, dates, medical, legal or financial information — against a reliable source.
Does it work on my phone?
