Persistent codebase knowledge
for you and your agents.
Self-healing bookmarks that survive refactors, share via git, and give your AI assistant persistent memory of your codebase.
AI agents lose context between sessions. Codebase knowledge lives in people's heads. Traditional bookmarks break on refactors. We built something that solves all three.
What's different
Your Agents Remember
A bundled MCP server lets Claude Code, Cursor, and Codex read, place, and repair bookmarks — no separate setup. Built-in skill guides teach agents best practices so you can say "map this codebase with bookmarks" and it knows what to do.
- ✦ 28 MCP tools for full bookmark lifecycle
- ✦ Works with any MCP-compatible client
- ✦ Zero-config: installs with the extension
Survives Every Refactor
Smart anchors store surrounding context — not line numbers — so bookmarks survive renames, moves, and formatting passes. Self-healing keeps them correct as code drifts; agent-assisted repair handles the hard cases.
- ✦ Context-based matching, not line numbers
- ✦ Background self-healing on file changes
- ✦ Agent-assisted repair for large refactors
Knowledge That Compounds
Shared bookmarks commit to git like code. New team members and agents inherit the map on clone. Groups, labels, and notes turn bookmarks into living documentation.
- ✦ Shared bookmarks in git, local stay private
- ✦ Merge-conflict-friendly storage format
- ✦ Groups and labels for organization
