The reading dilemma
You underline sentences. You draw margin lines. You scribble notes. Then the book goes back on the shelf, and the line is trapped in the object you marked.
What gets lost
- Highlights stay trapped inside closed books
- Margin notes get forgotten over time
- You cannot search across your physical shelf
- Manual typing takes too long to keep up
What BookQuotes does
- Photograph the marked page
- Isolate marked lines and review before saving
- Search full text across your entire reading history
- Export to Markdown, plain text, JSON, Notion or Obsidian
How it works
Three steps from a marked paper book to a quote you can search for later.
- 1
Photograph marked pages
Snap photos of pages with underlines, highlights, or margin notes. On-device quality assessment checks for blur and lighting before processing.
- 2
Extract and review
The app suggests the marked passage from the photo. Check the wording against the page, correct the page number if it is wrong, and add a note before you save.
- 3
Search, organize, and export
Search the passages, notes, titles and authors you saved. Filter the book list with tags and collections. Export one book or the whole library as Markdown, plain text, JSON, Notion or Obsidian.

Frequently asked questions
Clear answers on quote readers, personal book quote libraries, and capturing paper highlights.
What is a quote reader for physical books?
A quote reader for physical books is a tool that captures marked passages directly from printed pages and turns them into searchable digital text, complete with book title, author, and page citation.
Unlike generic document scanner apps that create flat PDF files or require tedious manual typing, a quote reader isolates the specific sentence, paragraph, or margin note you underlined on paper. For a step-by-step breakdown of how paper passages move to iPhone, read our guide to the quote reader app for physical books.
What is a book quotes website vs a quote dump site?
A personal book quotes website or library is a private, indexed record of passages you personally read and marked, whereas a quote dump site is a public catalogue of popular, out-of-context snippets.
Public quote websites and blogs often strip away publication dates, edition details, page numbers, and the surrounding argument to serve viral one-liners. BookQuotes acts as your personal reading archive instead: every quote anchors to the exact volume in your hands, your own margin reflections, and your private collections, with full export to Obsidian and Notion.
How does BookQuotes capture highlights from paper?
BookQuotes captures highlights from paper by photographing the marked page, extracting the underlined or highlighted passage using optical recognition or optional remote AI, and letting you verify the wording before saving.
You snap a clear photo in natural light, confirm the detected text against the original page image, and attach the verified title and edition via barcode ISBN scan. Once saved, your highlights become instantly searchable offline.
