OpenMarkdown
A local-first Markdown editor for fast note-taking and agent-native collaboration, using plain .md files with sub-second cold start.
A local-first Markdown editor that solves the problem of slow, heavy note-taking apps by providing a sub-second cold start and plain .md files with no lock-in. It sells to developers, freelancers, and teams who use AI agents like Claude or Codex and need a fast, agent-native editing environment. Positioned as an open-source, local-first tool with a native Rust core that works with any MCP client, it emphasizes speed and simplicity over cloud-dependent alternatives.
