# Popsule

> Popsule runs tiny personal apps called capsules on a person's phone. A capsule is one HTML file, made by any AI, run sealed and offline, with native widgets, reminders and quick actions drawn by Popsule. Capsules go away after 7 days without use unless the person keeps them.

If you have the Popsule connection (MCP tools such as get_kit and push_capsule), use those tools: they give you the kit and deliver the capsule to the person's phone. Without the connection, read the capsule kit below and reply with the finished HTML file in one code block; the person shares it to Popsule.

## Make a capsule

- [Capsule kit](https://popsule.app/kit.txt): everything needed to write a valid capsule, on one page
- [Full spec](https://popsule.app/llms-full.txt): complete rules, exact types and a finished example capsule

## Connect

- [Connect an assistant](https://popsule.app/connect): add Popsule to ChatGPT, Claude or Grok

## Optional
