Tell me about yourself so I can make the app just for you!
Leaf AI is a free, kid-safe learning app you can use in any browser โ no download, no sign-up, no cost. Leaf is a friendly leaf robot who chats with children, answers their questions in simple language, and turns learning into a game.
Inside the app there are ten things to explore: Chat with Leaf, a Cartoon Explorer with quizzes, a History section with a Second World War timeline, a World Religions guide covering Islam, Christianity, Judaism, Hinduism, Buddhism and Sikhism, Languages in English, Spanish, French, German, Italian, Japanese, Arabic, Sinhala and Tamil, a Game Mode, a School section with maths, science and English by school grade, a Talk page where Leaf reads answers out loud, a private Diary, and Stickers to collect.
Leaf AI is built for children roughly aged 5 to 17, works on phones, tablets and computers, and keeps a kind, encouraging tone with bad-word filtering built in. Leaf is a pretend robot buddy โ children are always reminded to check important things with a grown-up.

Leaf AI is a free learning app for children. It has no accounts, no ads, no tracking cookies and no sign-up. Most of Leaf works entirely inside your child's browser.
| Information | Where it goes |
|---|---|
| Nickname, birthday, country, language (welcome screen) | Used only in the open window to personalise greetings. Not sent anywhere. |
| Diary entries, stickers, progress | Saved in this browser on this device only. We never receive them. |
| Questions Leaf can't answer offline, and written exam answers | Sent to Leaf's own AI server, which runs open-source AI models on Cloudflare's network to create a reply. Before sending, Leaf removes email addresses, phone numbers, links and the child's nickname. We do not store these messages. |
| Internet address (IP) | Turned into a scrambled one-way code to stop overuse, kept up to 2 days, then deleted automatically. The real IP is never stored. |
| Voice (Talk tab) | Speech-to-text is handled by your browser or device maker (for example Google or Apple) under their privacy terms. Leaf only receives the typed text. |
Leaf follows strict child-safety rules, answers briefly in simple language, refuses unsafe topics, and tells children to speak to a trusted adult when they seem upset. A word filter checks both what children type and what the AI replies. No AI is perfect, so we encourage grown-ups to explore Leaf together with younger children.
You can delete diary entries inside the app, or remove everything by clearing this site's data in your browser settings.
