New in OCRBook
A clear plan for even the longest books.
The redesigned summary sheet makes local AI easier to understand. Pick what matters, preview the work, and stay in control from start to finish.
- Choose your context and summary length Match your Ollama model from 4K to 128K, then choose a quick, standard, detailed, or custom-length summary.
- Preview every step before starting See the strategy, estimated server calls, and a smarter context recommendation when a job is too large.
- Ask questions across the full document Long documents are searched part by part instead of being silently cut off, and any running workflow can be cancelled.

Everything in one reading space
From paper scan to useful knowledge.
OCRBook is built for real documents: multi-page books, imperfect scans, long reading sessions, and private workflows.
Page-aware OCR
Recognize long, multi-page documents while keeping the text connected to its original page.
Comfortable TXT reading
Switch from the scan to clean text with familiar page breaks, fast search, copy, and full-text export.
Listen with TTS
Turn recognized text into audio with system text-to-speech for hands-free reading and review.
Private local AI
Connect an Ollama server you control to summarize, translate, and ask questions about your documents.
Made for global readers
Expanded app interface language support makes OCRBook more approachable for readers around the world.

A book becomes searchable in four steps.

Good to know
A few quick answers.
Does OCRBook change my original PDF?
No. Your original file stays untouched. OCR text is stored separately, so you can switch between the scan and TXT view anytime.
Can I use OCRBook offline?
Yes. OCR and reading work offline. Ollama features need a network connection only when your configured server is on another device.
What happens with a very long document?
OCRBook plans around the context length you choose. It can split the document, summarize each part, and merge the results without silently dropping the end.
Can I stop a summary after it starts?
Yes. The workflow shows visible progress and can be cancelled at any time, which stops OCRBook from sending further requests.
