About ThreadPage
ThreadPage gives each project or client one thread of notes. Each time you work on it, you add a note at the end: text, checklists, tables, images or files. When you come back, the last note shows where you stopped, and the notes above it show how you got there.
Free runs in your browser without an account and works offline; your notes stay in that browser. The paid Pro plan adds sync across devices and sharing, and people you invite join free.
Pro also lets ChatGPT, Claude, Claude Code and Codex read and add notes over MCP, only in the folders and threads you choose. With the Claude Code or Codex plugin, each session gets its own @name: send it a request from any browser, and its answer comes back as a note.
ThreadPage has no built-in AI; the assistants run under your own plans. Notes are encrypted in transit and at rest, not end to end.
