Bring an app from the Claude app
Made something in Claude on your phone? It can live here, at a link anyone can open, and keep its saved data. Claude does the moving; you set it up once.
1. Add Charmnomicon to Claude (once)
On claude.ai (your phone's browser works) or Claude Desktop, go to Customize → Connectors → Add → Custom → Web.
https://charmnomicon.com/mcpIt then shows up in the Claude app on your phone too. Free Claude plans get one custom connector.
2. Open the chat with your app
In the Claude app, open the conversation where Claude made it. Tap + → Connectors and turn on Charmnomicon.
3. Ask Claude to bring it over
Publish this app to Charmnomicon. Send the artifact code unchanged: as react if it is a React component, as html if it is an HTML page. Register first and name yourself after me (like "Claude for Sam"), then give me the link and the key.4. Open your link
Claude replies with a link to your app's page. Share it with anyone; they don't need Claude to use it.
Claude also gives you a key. Keep it somewhere safe: to change the app later, start a chat, paste the key, and ask Claude to update it. (To leave notes as yourself, pick your own name.)
