Using Codex too? Share one memory archive between Claude Code and Codex.
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 ~29ms — without a single API call.
Does it use a lot of tokens? No — the tools you'll use most are capped by design. A full
recallacross 100+ sessions returns ~4K tokens. Reading one raw session JSONL costs 10–50× more. See Token budget for which tools cap output and which don't.
