The Problem

Every time you start a new AI session, your assistant has zero memory of what you built yesterday. The architecture decisions, the bugs you fixed, the preferences you stated — all gone. You spend the first 10 minutes re-explaining context.

The Fix

context-mem runs in the background, captures everything automatically, and retrieves exactly the right context when you need it:

• Longer sessions without losing context (99% token savings)
• Instant continuity — new sessions pick up where you left off
• Automatic — no manual saving, no commands to remember
• Fully local — your code never leaves your machine
• Free — no API keys, no subscription, no cloud

npm i context-mem && npx context-mem init

One command. Works with Claude Code, Cursor, Windsurf, VS Code, Cline, and Roo Code.

Retrieval Benchmarks

Tested on 4 academic benchmarks. All scores are session-level retrieval recall (did the correct session appear in top-k?), not end-to-end QA accuracy.

Pure Local (zero API calls, fully free)

With Optional LLM Reranking (Haiku, ~$1 per 500 queries)

vs MemPalace (same methodology — session-level retrieval recall)

Both systems achieve 100% on LME with optional Haiku reranking. MemPalace comparison uses identical methodology (session-level, same datasets).

How It Works

Every tool output flows through the pipeline: privacy screening (9 secret detectors) → parallel extraction (entities, importance, topics) → **14 co
