Kit beta: a local-first AI memory layer on Mac that syncs context across Claude, Cursor and Codex
peterjohnkoen · reddit · 2026-11-12
A Redditor launched the free beta of Kit, a UX-forward AI memory layer that runs locally on your Mac, built on the idea that memory should belong to users rather than sit on frontier providers' servers as a lock-in moat.
Key design
- Local storage: memories live in a database on your machine with no Kit cloud server; you pick the LLM for reasoning (local or cloud), and a "Local only" mode keeps everything on-device.
- Cross-tool sharing: any MCP-speaking tool (Claude, Claude Code, Codex, Cursor) connects via UI, sharing one context about you and your work — no more re-explaining everything when you start a session or switch tools.
- Browsable and correctable: a real UI to inspect memories, see where each came from, and fix or delete them.
- Sources as sacred: Kit keeps links to the source material behind each memory so errors can be traced back and validated.
- No lock-in: standard JSON export/import.
- "Dreaming": a scheduled nightly consolidation cycle that forms new memories, links important items, forgets trivial ones, resolves conflicts, and tests memory continuity.
Mac-only for now; solo product dev actively soliciting blunt feedback from diverse workloads.
