How can we help?

Tobi supports EPUB and PDF files that are DRM-free. Most ebooks you buy from Kindle or Apple Books have DRM protection and cannot be imported — the file will appear to open but Tobi won't be able to read the text inside.

Recommended: Use the built-in Get Books tab to download from Project Gutenberg — 70,000 public domain classics, always DRM-free.

Books purchased from Kindle, Apple Books, Kobo, and most major retailers include DRM (Digital Rights Management) copy protection. This prevents any app other than the official reader from accessing the text — including Tobi.

DRM-free alternatives:

• Standard Ebooks — free, beautifully formatted public domain books
• Smashwords — indie authors who sell DRM-free
• Humble Bundle — frequent book bundles, always DRM-free
• Tor Books — major sci-fi/fantasy publisher, DRM-free

• AirDrop from Mac: Right-click the EPUB file on your Mac → Share → AirDrop → your iPad.
• iCloud Drive: Save the file to iCloud Drive on any device. Open Tobi → Import → Browse Files → iCloud Drive.
• Email attachment: Email the EPUB to yourself, open the attachment on iPad, tap Share → Copy to Tobi.
• Safari download: Download directly in Safari — the file appears in Files → Downloads.

Yes — Tobi registers as a handler for EPUB and PDF files on your iPad. From any app that supports sharing (Safari, Mail, Files, Dropbox), tap the Share button, then tap Open in Tobi.

Note: If "Open in Tobi" doesn't appear, scroll right in the share sheet or tap "More" to enable it.

Long-press any book card in your Library to reveal the delete option. This removes it from your library and frees storage on your device. Any existing conversions are unaffected.

The first chapter is typically ready within 60–90 seconds. Remaining chapters generate in the background while you read — by the time you finish chapter 1, chapter 2 is usually already done.

Total conversion time for a full novel is typically 8–15 minutes, but you don't need to wait — reading starts immediately after the first chapter.

Tobi includes 8 preset styles: Akira, Grimoire, Horror, Sci-fi, Shonen, Noir, Romance, and Epic. The style input also accepts any freeform description. Try things like:

• "Watercolour with ink outlines, Studio Ghibli palette"
• "Soviet propaganda poster style, bold geometric shapes"
• "Ukiyo-e woodblock print, traditional Japanese colours"

The more specific you are, the more consistent the results.

Yes — each conversion uses one of your monthly slots. Pro subscribers get 5 conversions per month and Lifetime subscribers get 10, so you can convert the same book in different styles within your monthly allowance.

You can navigate away from the progress screen at any time — generation continues in the background. To fully stop a conversion, force-quit the app. Any panels already generated will be lost and the conversion will need to be restarted.

Tobi builds a character consistency profile from the full text of your book before generating any panels. For most books this works very well. Occasional variation can happen when a character appears rarely or is described vaguely. Try converting again — a second attempt often produces better results.

Blank panels usually indicate that a scene was too short or abstract for the AI to generate a meaningful image — philosophical passages or very short transitional scenes sometimes produce this. It can also be caused by a temporary API timeout.

To fix: long-press the book card → Regenerate. This will only regenerate the missing panels.

Tobi reads the text layer of PDF files. If your PDF is a scanned image (a photo of a physical book), there is no text layer and Tobi cannot extract the content. Try selecting text in your PDF — if you can't, it's image-based. EPUB format works better whenever available.

The biggest impact comes from a more specific style description. Instead of "manga style", try "black and white manga with heavy ink lines, dramatic shadows, close-up character expressions, cinematic panel composition".

If the crash is reproducible, please with details — this helps us fix it quickly.

Your library and already-converted graphic novels are available offline. Converting a new book requires internet as it uses AI services to generate the panels.

The app itself is small (~50MB). Each converted graphic novel takes approximately 15–20MB. A library of 10 converted books uses roughly 150–200MB total.

1. Open Settings on your iPad
2. Scroll down and tap Tobi
3. Tap Notifications and make sure they're enabled
