An independent, open-source document library: an Android app and a Linux desktop app (COSMIC) that keep the same documents in sync over the local network. Scan or import documents, read their printed text offline, file them into stacks, search and export them. No account or cloud service is involved.
Stack is not affiliated with Google and contains no code, assets or models from Google's discontinued Stack app.
