permark

PerMark is the desktop IDE for the post-AI engineer—where humans and AI agents plan, mature ideas, formalize specs, and steer development using Markdown as their shared language.

Got a .md file?
- Open any standalone .md file as a clean, well-typeset page—Mermaid diagrams, LaTeX math, tables, and ~190 syntax-highlighted languages.
- Edit in place visually (WYSIWYG) or in source mode with YAML frontmatter validation.
- Keep a self-saving scratchpad (Notes) with zero save dialogs.

Build with AI agents?
- Open a project folder as a live workspace that watches what your AI agents write across branches and git worktrees.
- See what changed since you last read (Unread view) with block-level diffs (Added, Rewritten, Removed).
- Leave inline comments on any passage and let your agent read and resolve them via PerMark's built-in MCP server (permark mcp) or CLI hook (permark context).
- Works with any AI tool (Claude Code, Codex, Cursor, Gemini CLI, OpenCode, Cline, Aider, Hermes Agent, OpenClaw...) or none.
