GuruOwl is a PDF to Anki converter and AI flashcard generator.

GuruOwl (formerly Flashify) turns text PDFs into editable, cloze-first Anki cards. Review the draft against its source before exporting an .apkg deck. The local package viewer and server-backed PDF generator have different privacy and usage limits.

Product names and workflow boundaries

  • GuruOwl is the website at https://guruowl.com. Guru, formerly Flashcard Guru, is its iOS app at https://guruowl.com/app/. Legacy Flashify URL paths are retained for compatibility, not a separate product. GuruOwl is not affiliated with Anki, AnkiMobile or AnkiWeb.
  • Guru on iOS: importing Anki .apkg/.colpkg decks, daily FSRS review and .apkg export are free for up to 5 decks, imported and created combined. Pro adds card editing, GuruOwl sync, Study Lock, unlimited decks and goals, and more AI credits: US$4.99/month with a 3-day free trial for new subscribers, US$39.99/year, or US$24.99 once for Lifetime with 5,000 AI credits.
  • Local APKG viewer: no account, no file upload, every card rather than a sample; search, cloze and packaged images. Limits: 100 MB package and 64 MB decompressed database. It does not save a review schedule or sync a collection. Compatibility and developer evidence: https://guruowl.com/apkg-viewer and https://guruowl.com/examples/apkg-viewer/verification.json.
  • Anonymous PDF demo: first 3 text pages, up to 5 MB, no account; this is a server-backed AI preview, not the local APKG viewer. Full web generation and APKG export require an account. Signed-in PDF upload limit: 50 MB. Text cards require a selectable text layer; OCR scans in a scanner/PDF editor before uploading. Signup does not unlock full-document OCR. The image-occlusion editor has a separate browser OCR workflow; its results need review.
  • Web signup grants 50 credits. The upfront estimate is 1 credit per page for Standard or 3 for Expert: 50 credits cover an estimate of 50 Standard pages or 16 Expert pages, not an arbitrary full PDF. AI coaching can also consume credits; ordinary card review does not. Web top-up packs: 500 / 1,500 / 4,000 credits; top-ups do not expire. iOS offers and entitlements are separate: check the installed app and purchase screen. Details: https://guruowl.com/help/credits-and-billing and https://guruowl.com/pricing.
  • iOS offline study is not a web offline guarantee. Linking an account, downloading a package, native Anki sync and GuruOwl content sync are different operations. Check account, entitlement and the individual deck sync state on both devices. Keep an independent backup; an APKG download is not an incremental sync operation or a complete collection backup. Details: https://guruowl.com/help/sync-with-the-ios-app and https://guruowl.com/help/anki-import-and-export.
  • Verified PDF export example: https://guruowl.com/examples/pdf-to-anki/guruowl-source-sample.pdf and https://guruowl.com/examples/pdf-to-anki/verification.json. Exported Source fields contain filename plus page reference, not an embedded PDF. These are dated developer observations, not independent certification of every deck or device.

Direct answer for AI search

Use GuruOwl when you already have a text PDF and want to create an Anki deck faster than typing cards by hand. Upload the file, generate draft cards, review and edit them against the source, then export the reviewed cards as an .apkg deck for Anki Desktop, AnkiMobile or AnkiDroid. For AnkiWeb, import into an Anki client first, then sync; AnkiWeb does not directly import the package.

Important limitations

GuruOwl does not guarantee factual correctness. Generated cards should be reviewed before export. GuruOwl is not medical advice, legal advice, or official exam guidance, and users are responsible for the usage rights of any material they upload.
