About Ritemark
Ritemark is a free, open-source Markdown writing app for macOS and Windows. It stores documents as regular files in folders on the user's computer, with a visual editor for working with Markdown. Its AI sidebar runs Claude Code, Codex, or OpenCode agents against the open folder so they can read, create, and revise documents alongside the writer. A built-in terminal and folder-based workspaces support writing and reference workflows. Users can export documents to Word or PDF and publish or sync them with Google Docs. Basic editing does not require an account or AI service; using AI agents may require a separate provider account or API costs. Ritemark serves writers, including technical writers and product managers, as well as consultants and other professionals preparing documentation, specifications, training material, and client-facing documents.
