As answered by people managing Jackmail and PlainHub.dev.
PlainHub.dev's answer:
Your files live in your own GitHub repository, not on our servers, and every save is a Git commit. On top of that editor, PlainHub connects to the Claude Code running on your own PC, so you can use it from a browser or your phone and approve its proposals from anywhere.
PlainHub.dev's answer:
Developers who use Claude Code and keep notes, docs, or plans in GitHub, and want to read, write, and approve from a browser or phone.
PlainHub.dev's answer:
Plain JavaScript, CodeMirror, marked, DOMPurify and Mermaid in the browser; Cloudflare Pages and Functions; a GitHub App on the GitHub REST API; and a Node.js CLI and MCP server (Model Context Protocol SDK).
PlainHub.dev's answer:
I jot down ideas on my phone on the train, and my notes keep getting longer. Many note apps can get slow once a single note grows very long. I wanted plain text files in my own GitHub that stay fast at any length and open on any device. My main note is now about 26,000 lines and still opens quickly. Later I connected it to the Claude Code on my home PC, so I can search my notes and past logs from my phone.
PlainHub.dev's answer:
Choose it if you want your notes and docs in a GitHub repo you own, with full history, and you want to write them from any device without using git. It also suits people who already use Claude Code: your agent can search and edit the same repo, and its decisions stay in Git.
