## Summary

Jevmem is an open-source tool that automatically saves decisions, constraints, bugs, and todos from Claude Code chats into a structured markdown file called **JEVMEM.md**. Built on **Jev**, a system by TypeSafe AI, it integrates as a plugin for Claude Code, Cursor, and Codex, marking superseded lines instead of deleting them. The tool uses a lightweight LLM to decide whether to save a turn, with a median decision time of **0.30 seconds**—faster than six current LLMs tested, though less accurate than **GPT-6 Astra** or **Claude Opus 5.5** on save+kind classification.

Jevmem includes security features like scrubbing sensitive data (API keys, passwords) and a poisoning gate to block malicious instructions. It supports retries for Jev outages and offers CLI commands for initialization, auditing, and manual memory management. The project is early-stage, with benchmarks limited to held-out turns and no long-term recall testing. Users must provide a **TypeSafe API key** (OpenAI or Anthropic keys are optional).

## Key points

- Jevmem saves Claude Code chats as structured markdown with timestamps, confidence scores, and superseded-line tracking
- Uses a fast, low-cost LLM (Jev) for decision-making, outperforming others in speed but trailing in accuracy
- Includes security features like data scrubbing and poisoning gate, but relies on TypeSafe’s terms for retention

## Why it matters

For developers using Claude Code, Jevmem automates project memory capture, reducing manual note-taking and improving context retention. Its speed and cost efficiency make it appealing for real-time workflows, though accuracy trade-offs may limit adoption for critical decisions.
