Sutra - eBook & Comic Reader
Smart panel comic & ebook reader with OPDS server sync
Sutra is an iOS reader for books, manga, and comics with total data privacy - zero tracking and no servers required. • Smart Panel Detection: Isolates comic & manga panels at 90% accuracy for mobile screens. • Offline & Cloud Sync: Load local files directly or connect to Kavita, Calibre, Komga, Grimmory, & WebDAV via OPDS. • Native Formats: EPUB, PDF, MOBI, & CBZ. • No Subscriptions: Free core app. One-time $6.99 lifetime unlock for CBZ/MOBI/Komga (with a free 7-page preview).
Introducing Sutra: an ebook and comic reader with smart panel detection for your DRM-free content.
There are plenty of ebook reader apps, but I built this for two reasons. First, you shouldn't have to pay a recurring subscription to read content you already own. Second, reading comics on a phone is best done panel by panel and needs a good panel parser, and all the existing options I found lock this behind a subscription.
Sutra handles ebooks, manga, and comics directly on iOS without any server dependencies. It also operates with total data privacy - zero data is collected.
Here are the core features: - Smart panel detection: Custom engine isolates comic and manga panels at 90% accuracy for mobile reading. - Format support: Reads EPUB, PDF, and CBZ, and includes a custom-built native parser specifically for MOBI. - BYO Library: Load files directly from device storage, or sync via OPDS with Calibre, Kavita, Komga, Grimmory, and WebDAV. - No subscriptions — Core app is free. CBZ, Komga, and MOBI integrations are a single $6.99 lifetime unlock (includes a 7-page free preview).
Let me know if you have questions about the panel detection engine or the server integrations. I am currently working on an Android port for Sutra. Feel free to follow along for updates!
