Show HN: Persistent memory for Claude Code sessions

I kept watching Claude Code spend 10 minutes re-exploring files it already analyzed yesterday. Same patterns, same architecture, every session starting from zero.

So I built grov. It runs a local proxy that intercepts Claude Code's API calls, captures reasoning from each session (via LLM extraction), stores it in SQLite, and auto-injects relevant context into future sessions.

In testing: baseline task took 10-11 min with 3+ explore agents launched. With context injection: 1-2 min, zero explore agents. Claude just reads the files directly because it already knows the codebase patterns.

How it works:

-Run grov init

- Run grov proxy (keep it running)

- Use Claude Code normally

- Grov captures what Claude learns, injects it next session

It's local-only (SQLite), nothing leaves your machine. Currently ~250 npm downloads with no promotion, which pushed me to share it here.

Still early (v0.2.2). Would love feedback from Claude Code users. Please report bugs!

How do you ensure each memory is still relevant?

That thing is 15kLOC of Typescript vibe-coded over the span of two days. At this point you're better off asking an AI if you have a question about what the code does...

What value does it provide over, say, just asking Claude to keep state in a markdown file that it can access across sessions?
