About

Tweet compose mode for drafting replies/QTs with pixel-accurate X/Twitter UI. Plain .md files on disk — no database, no lock-in. Use when user says: "open writer", "openwriter", "write in openwriter", "edit my document", "review my writing", "check the pad", "write me a doc", "compose tweet", "reply to tweet", "quote tweet", "author's voice", "authors voice", "learn my voice". Requires: OpenWriter MCP server configured. Browser UI at localhost:5050.
