AI goldfish gets a diary
Show HN: Linggen – A local-first memory layer for your AI (Cursor, Zed, Claude)
Your AI keeps forgetting? Linggen turns it into a local memory machine—and the crowd is split
TLDR: Linggen claims to give your AI real memory by indexing projects locally so it can recall decisions and dependencies. The community loves the privacy and idea but splits hard: fans say it’s a practical fix, skeptics say it’s just fancy documentation and want proof it truly manages context
Linggen hit Show HN promising an AI that finally remembers your stuff: it indexes your projects on your own computer, builds a map of how files connect, and stores key decisions as simple notes so Cursor, Zed, or Claude can stop acting like goldfish. The creator popped in to say they built it after “re‑explaining the same context” over and over. Cue the comment drama: some cheered the local-first, private angle—no cloud snooping, no accounts, just vibes—while skeptics asked the blunt question: isn’t this just… writing better docs? The spicy debate centered on whether Linggen is magic or housekeeping. One camp loves the persistent memory and cross-project recall, saying it’s like giving your AI a diary. The other camp asked for proof: does it compress the info or actually manage context better than a wiki? Mac-only for now sparked light grumbling, and the paid team license got side-eye (“free for individuals” means “wait till my boss pays”). Jokes flew fast: “therapy for Claude,” “AI with a brain,” and “blast radius map” became the meme of the thread. Even the skeptics agreed the on-device indexing is refreshing. Whether it’s game-changer or glorified documentation, HN showed up with popcorn and opinions, as usual
Key Points
- •Linggen is an open-source, local-first memory layer that indexes codebases and team knowledge for AI assistants.
- •Persistent memory is stored in .linggen/memory as Markdown and recalled via semantic search using LanceDB.
- •It integrates with MCP-enabled IDEs like Cursor and Zed, with Claude support on the roadmap.
- •A VS Code extension offers Graph View and automatic MCP setup; macOS CLI is available, with Windows/Linux support coming soon.
- •Free for individuals under the MIT License; commercial licensing is requested for teams, with planned enterprise features such as SSO, Team Sync, and RBAC.
