# Where plans get made. And then get done.

A native Mac notes app. You write in plain markdown, in a folder you own. Your
coding agent works in the margin, waiting for your yes.

[Download for macOS](https://github.com/princeharshan/grapha-site/releases/latest/download/Grapha.dmg)

This is the markdown mirror of <https://grapha.ai/>. The HTML page is the same
words with the design attached, and a 2 minute 38 second screen recording of
the app doing what is described below.

## What it is

Grapha is a markdown editor for macOS that renders what you write instead of
showing you the syntax, and keeps the file on your disk exactly as markdown the
whole time. Notes live in `~/Grapha`, one folder per note, holding a `note.md`
plus its images and history. Nothing about a note is proprietary: open the
folder in any editor, or in git, and it is all there.

There is no filing. No folders, no projects, no templates — you write, and the
note exists. Documents carry labels rather than a location.

## What the agents do

Label a document and the coding agent you already use can work inside it:
Claude Code, Codex, or Cursor, running under your own subscription or API key.
An agent writes in the margin — a comment, a suggested edit — and nothing it
proposes lands in the file until you accept it.

Agents see only the documents you label. Everything else in the folder is
invisible to them.

## Live numbers

A note can be connected to a read-only database, so a number in a sentence or
a chart in a page is the real current figure rather than one typed out months
ago. The app runs the query locally; a model is never given a credential and
never executes anything. Connections are read-only, and the credential lives in
the macOS Keychain.

## Free to write. Forever.

The markdown editor is free for everyone. The agent harness is $49 — once, not
a month.

- Your notes are plain markdown files, in a folder you own.
