Grapha.ai is a native note-taking app for Mac, with the core positioning of combining plain Markdown notes with coding agents. The official description emphasizes "Free to write, forever," meaning the Markdown editor is free forever for everyone.
Main capabilities and usage: Notes are saved as plain Markdown files in a folder the user owns, with no proprietary format lock-in. The agent harness is a one-time $49 purchase rather than a monthly subscription; it can run the coding agents users already use, including Claude Code, Codex, or Cursor. Agents can only read documents the user has labeled, and other content is invisible to them, providing a certain degree of access control. In addition, notes can be kept active by referencing numbers or logic from connected databases.
Supported platforms and limitations: It supports Apple silicon and requires macOS 14 and later, with no account required. Agents are provided free for 30 days from first run. Apart from the information above, the materials do not provide further details about specific features, pricing, usage steps, or results.
