Innermost: Book Notes & Ideas

Innermost turns your paper books into a personal library of highlights, notes, and ideas.

Scan a page with your phone. Innermost reads it on-device, lets you highlight the passages that matter, and keeps your own thoughts beside the exact words that inspired them. Revisit the page later, compare it with the original photo, search book titles and saved passages, or export your notes in Markdown or plain text.

READ WITHOUT RETYPING
Photograph a page and Innermost recognizes the text for you. Choose a sentence or paragraph, highlight it, and add a thought without copying anything by hand.

KEEP THE CONTEXT
Your notes stay connected to the book, page, and passage they came from. Open a page to see the full text with your highlights, or switch to the original photo whenever you want to check the source.

FIND IT AGAIN
Search across book titles and the passages you saved. Go back to an idea months later without remembering which book or page it came from.

MAKE IT YOURS
Correct OCR mistakes, edit page numbers, manage your books, and export notes as Markdown or plain text. Share a page when you want to keep a passage somewhere else.

PRIVATE BY DESIGN
No account is required. Your book pages, highlights, and notes are stored on your phone. Text recognition runs on-device, and your book content is not uploaded to us. The core reading and note-taking features work offline.

A NOTE ON RECOGNITION
OCR is not perfect, especially with curved pages, unusual fonts, or poor lighting. Innermost lets you review and edit every recognized page, so your notes always remain under your control.

Innermost is made for reading, study, research, and personal note-taking. It is not a replacement for the original book.
