ManualBook

Paper manuals pile up in drawers — and the one you need is never there. ManualBook turns that pile into a searchable library on your phone. Now it also answers your questions and finds the right manual from a photo.

Scan a manual with your camera, snap a photo, or import a PDF. ManualBook reads every word on the page — in English, Spanish, German, French, Chinese, Japanese, and more — entirely on your device, so you can find any detail in seconds.

How it works
• Capture: the built-in document scanner auto-detects edges and straightens the page. Or import straight from Photos or Files — images and PDFs alike.
• Recognize: on-device text recognition reads each page, including mixed English / Chinese / Japanese, with no internet and nothing uploaded.
• Search: full-text search across every manual and every page, with matches highlighted and a tap to jump right to the page.
• Ask: ask a question in plain language and get an answer drawn from your own manuals — generated by on-device AI, with page citations, and nothing uploaded.
• Identify: not sure which manual you need? Snap a photo of the product and ManualBook matches it to the right manual — on-device.
• Organize: group manuals into folders, add tags, and keep brand and notes together.
• Share to ManualBook: send a PDF or photo from any app — Safari, Files, Mail, Photos — straight into your library, scanned and filed automatically.
• Export: turn any manual back into a shareable PDF.

Private by design
• Everything runs on your iPhone. Text recognition and AI answers happen on-device — your manuals are never uploaded to us, and there are no accounts, servers, analytics, or trackers.
• Optional iCloud Sync keeps your library in your own private iCloud, encrypted by Apple, so it's there on all your devices. We never see it.

Free to start
• Your first manuals are on the house. A single one-time purchase unlocks unlimited manuals and AI answers — no subscription.

Stop hoarding paper. Scan it once, find it forever.
