Games, play & app making

Play a game, or build one yourself

Open the app · free →

Say "Let's play Gomoku" and the board appears with an AI that chats as it plays. Ask for hints or change the difficulty; chess, janggi (Korean chess) and Go-Stop are there too. Exchange a room code to play remotely with a friend far away.

Say "Make a brick-breaker game" or "Make a calculator app" and it builds the game or app on the spot and runs it immediately. YouTube search and summaries, and time travel through old newspapers, are in the play section as well.

Frequently asked questions

Does it work on a phone?

Can I keep an app I made?

Save it as an HTML file and open it again.

How does remote play work?

Create a room code and send it to a friend to join.

How this differs from other AI apps

It remembers you. Names, family, appointments, tastes — say it once and it carries into the next conversation. Memory is stored on your own device, never on our servers.

Free, and meant to stay free. No ads, no third-party tracking. Only when heavy thinking is needed does that single question go to the AI provider you chose (Gemini, Groq, etc.).

31 languages, on phone or PC. Opens in the browser with nothing to install, and can be added to your home screen like an app.
