The real workflow: Calibre as the hub
The apps above solve different problems, and they don’t talk to each other. Here’s how they fit together: Calibre is your library of record — it holds every file, every cover, and all metadata. Goodreads or StoryGraph tracks what you’re reading and want to read. When you finish a book on your Kindle, the reading status syncs to Goodreads. When you discover a new book on StoryGraph, add it to Calibre so you know you own it (or plan to). Calibre’s “Reading List” plugin bridges the gap — create a “Want to Read” list, and Calibre can auto-sync those books to your device when you connect.
Gotcha: Goodreads metadata overriding Calibre metadata
If you use the Goodreads Sync plugin in Calibre, be aware that syncing can push Goodreads’s metadata back into Calibre, overwriting your carefully curated tags. Set the plugin to one-way sync (Calibre → Goodreads) unless you’re intentionally managing your library from Goodreads. Similarly, Kindle’s auto-sync with Goodreads only works for books purchased from Amazon — sideloaded books need to be manually marked as “Currently Reading” in the Goodreads app.
Pro Tips
- Use Calibre metadata download (Edit Metadata → Download Metadata) to auto-fill covers, descriptions, and tags
- Create collections on your Kindle/Kobo by author or genre
- Back up your Calibre library — it contains all your books and metadata
- Deduplicate first before organizing — Calibre’s Find Duplicates plugin saves hours of manual checking
