PlainHub is a Markdown and plain-text editor for your own GitHub repositories, wired to Claude Code. Open a file in your browser or on your phone, write, and save — every save is a Git commit, so your history is always there.
Connect the Claude Code running on your own PC and use it from any browser or your phone, by text or hands-free by voice. Your agents keep a shared ledger of progress and decision cards in your repo, and you approve from anywhere.
Your files stay in your GitHub: PlainHub's servers don't store them, and you grant the GitHub App access only to the repositories you choose.

GitHub, without the git

Your Claude Code, wired in

A shared ledger for agents and people
Agents post progress notes and decision cards in your repo; you approve or decline from PC or phone.
Search across all your repositories
One search box for every repo you've connected.
An AI panel you stay in control of
It proposes edits you review before they are applied.
Organize it like a drive
Folders, drag and drop, and previews for images and PDFs; one commit each.
Safe by design
History, diffs, and a compare screen; PlainHub asks instead of silently overwriting.
MCP server and CLI
On npm (plainhub), listed in the MCP Registry. Tested with Claude Code.
Your files stay in your GitHub
PlainHub's servers don't store them; you choose which repos the GitHub App can access.
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.
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.
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).
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.
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.
