Use tool ↗About Grapha
Grapha is a native macOS notes app built around plain markdown files that live in a folder the user controls rather than a proprietary database. Its paid feature lets coding agents such as Claude Code, Codex, or Cursor work inside the margins of a note, proposing edits and pulling in outside data while the user reviews and approves each change rather than granting the agent free rein. The markdown editor itself is free with no account required; the agent integration is a one-time $49 purchase after a 30-day free trial of that feature. It requires an Apple silicon Mac running macOS 14 or later, and appears to be built and maintained by an individual developer rather than a registered company, based on its minimal public footprint.

Pros & cons of Grapha
Grapha's core idea, notes as plain markdown files you own with coding agents proposing rather than making edits directly, appeals to people who already distrust proprietary note databases and want AI help without losing control of their files. It is a narrow, single-platform tool: no Windows, Linux, iOS, or web version, and the agent feature only pays off if you are already using Claude Code, Codex, or Cursor.
Pros
- Notes stay as plain markdown files in a folder you own, not a proprietary database
- Free markdown editor with no account required, so there is no cost to try the core app
- One-time $49 payment for the agent feature rather than an ongoing subscription
Cons
- Mac-only, and specifically Apple silicon on macOS 14+, with no Windows, Linux, or mobile support
- Agent integration only supports three specific coding agents, so its value depends on already using one of them
- Minimal public information about the developer or company behind it
Best for
- Mac users who want plain markdown notes instead of a proprietary app database
- Developers already using Claude Code, Codex, or Cursor who want them working inside their notes
- Users who want to review and approve AI edits rather than let an agent write directly
Not for
- Anyone not on an Apple silicon Mac, since there is no Windows, Linux, or mobile version
- Users who do not already use one of the three supported coding agents, since that is the paid feature's whole value
