OpenMarkdown is a feather-light, local-first Markdown editor designed for seamless collaboration with your agent, ensuring your notes remain plain .md files on your disk without database lock-in or third-party interference.
Key benefits include:
- Local-First Architecture: Notes are stored as plain .md files on your disk, with no database, lock-in, or cloud dependency, ensuring data privacy and portability.
- Agent-Native Collaboration: Integrates with your existing AI agents (Claude, ChatGPT, Gemini, etc.)—no AI inside the editor, just powerful collaboration on your terms.
- Ultra-Fast Performance: Cold start in under 1 second (P50), with 0.2s window opening, minimizing waiting time.
- In-Place Agent Rework: Drag-select text, ask your agent to rework it directly in the file, eliminating copy-paste workflows and keeping content in its original context.
- Multi-Mode Editing: Switch between live preview (real-time rendering), plain source (syntax-coloured text), and clean reading (distraction-free view) with one key.
Perfect for developers, content creators, and productivity-focused users who need a lightweight, agent-integrated Markdown editor for note-taking, knowledge management, and collaboration without relying on cloud services.
