graincrawl is a local-first CLI tool written in Go that archives Granola meeting notes, transcripts, panels, and metadata into a private SQLite database. It supports multiple read-only source adapters: Granola's private desktop API (via WorkOS token), the official public API (with a scoped API key), the local plaintext desktop cache, and legacy encrypted JSON files (via Electron safeStorage decryption). The tool provides commands for syncing, searching, exporting Markdown, creating portable snapshots, and browsing via a terminal UI. The architecture is cleanly modular with separate packages for each source adapter, a shared SQLite store with schema migrations, and a syncer that orchestrates fallback logic between sources. The codebase is well-tested, has comprehensive CI/CD, and follows Go best practices. It is not a data research project; it is a production-grade application for personal data archiving.
