Borrow the starting point
The docs include a counter you can run. Give them to your AI assistant when you want to make something different.
Small apps, ready to share
Try this one Then build yours
Tap the counter. Then put your own idea behind a link: a scorekeeper, a live game or a guide that answers questions. Gem runs the app. People open it in Telegram.

Send one message
Paste up to 4,000 characters of JavaScript or TypeScript into Gem. It runs the code and replies with a link.
03
Put it in a chat
Open your app and use Share. Friends follow the link inside Telegram. When you update the code, that same link opens the new version.
A document works, too. Send Gem /newapp, then a PDF, Markdown, JSON or text file to make a searchable guide. For code apps, AI, storage, leaderboards and live rooms are ready to use.
