CAUTION

Publisher claims: "The recorder for your AI conversations: byte-exact copies of your Claude Code, Codex and Pi sessions (Claude Code deletes its own after 30 days by default), searchable over MCP with cited-or-abstain recall. Local-only." Observed in sandbox: no network, touches nothing outside the project, writes no memory.
