Anthropic API key

Prompt editing runs against your own key. It is stored in this browser only and sent only to api.anthropic.com — there is no server in the middle. Create one at console.anthropic.com.

MCP bridge

Let Claude Code — or any MCP client — measure and edit these models. Its edits arrive as ordinary revisions you can undo. Because the models live in this browser, the tab has to stay open with the bridge on for an agent to reach them.

Storage

Your models, edit history, folders and constructs live in this browser’s database. Clearing site data deletes them, and they do not follow you to another browser or machine.
