- OpenMarkdown is a local-first, feather-light, and fast Markdown editor built for users and their agents.
- It uses a native Rust core, ensuring quick loading times and native performance.
- The editor is AI-free; instead, it runs on the user's existing agent, providing direct integration.
- Files are stored as plain .md files on the user's disk, avoiding databases and lock-in for persistence and portability.
- Agents can interact with files as a wiki, opening the correct file and navigating to specific spots upon user queries.
- Features include agent-assisted highlighting and reworking of selected text, saved directly to the disk.
- Vendor options with varying speeds and SSO support are available at different monthly prices.
- Keyboard shortcuts like Ctrl+G and Cmd+P enhance control, allowing prompt access and file navigation without menus.
- Three editing modes (live preview, plain source, clean reading) are cycled with one key, with visible, syntax-colored markers.
- The editor supports collaborative planning with agents, as shown in an example of drafting an auth revamp plan.
- It ensures file integrity by not reformatting text, provides safe defaults like moving deleted files to Trash, and avoids accounts or cloud telemetry.
- The UI is trilingual (Chinese, Japanese, English), with a CLI tool for terminal file opening, and standard Mac shortcuts are supported.
