**Persistent local memory for Claude Code.** Every tool call, every file edit, every thinking block from every Claude Code session — stored verbatim on your machine. Searchable, replayable, and recallable by fuzzy natural-language questions. Zero API calls. Zero summaries. Zero decisions made by an AI about what's worth remembering.

**Claude Code quietly rotates your session files after a few weeks.** Longhand captures them into SQLite before they're gone. Once ingested, your history stays forever — even after the source JSONL files are deleted. Install early; the past you don't capture is unrecoverable.

**If you have 20+ Claude Code sessions in `~/.claude/projects/`, Longhand can search across every fix, decision, and conversation you've had in ~56ms — without a single API call.**

**Does it use a lot of tokens? No — every tool is capped by design.** A full `recall` across 100+ sessions returns ~4K tokens. Reading one raw session JSONL costs 10–50× more. See [Token budget](#token-budget).

pip install longhand
