The AI workspace for your book highlights

The AI workspace for your book highlights

You've read thirty books this year and highlighted the best passages. The problem is retrieval. The highlight about leadership from the business book is in Kindle. The passage about habit formation from the psychology book is in Apple Books. The quotes you hand-typed from the library copy are in a notes app. Each reading app holds its own highlights in its own silo, and the connections between ideas across books exist only in your memory, which fades faster than the highlights accumulate.

The real value of highlighting isn't marking a passage. It's being able to find it later when it's relevant to something you're thinking, writing, or discussing. "What did that author say about feedback loops" is a question you can answer right after reading and can't answer three months later, because the highlight is buried in a reading app you've since filled with fifty more books.

Fabric makes every highlight searchable by theme and connects ideas across your full reading library. The passage about feedback loops is findable six months later because the search understands what it says, not just which book it was in.

Search highlights by meaning across every book

AI search reads every highlight and searches by theme, argument, and concept. "Every passage I highlighted about decision-making under uncertainty" finds the relevant highlights from the psychology book, the business book, and the memoir across your full library. "The quote about compounding from the investing book" finds the specific passage. "What have I highlighted about creativity" finds every relevant highlight across dozens of books.

The search connects across books, genres, and reading apps. A highlight from a biography connects to one from a business book when the theme is the same.

Import from wherever you read

Import highlights from Kindle, Apple Books, and other reading apps via Readwise integration or by copying into notes and docs. Forward highlights from email to email-to-note. Type highlights from physical books. Photograph highlighted passages with the mobile app and the handwriting scanner extracts the text. Every highlight ends up in one searchable library regardless of where you read.

The AI connects ideas across books

The AI assistant works from your full highlight library. Ask it to find the common thread across highlights from five different books. Ask it what different authors said about the same topic. Ask it to connect a highlight to something you're writing. Ask it to surface the most relevant passages for an argument you're developing. The cross-book synthesis that used to require a photographic memory happens in seconds.

This is especially valuable for writers, researchers, and content creators who draw on reading for their work. The AI can surface the right reference at the right moment from a library of thousands of highlights.

Annotate highlights with your thinking

The highlight captures what the author said. The annotation captures what you thought about it. Annotations let you add your reaction, your disagreement, your connection to another idea, or your plan to use the passage in something you're writing. The annotations are searchable, so "every highlight where I noted a connection to my project" or "passages I want to use in the newsletter" finds the relevant set.

Connected to your broader knowledge base

Highlights don't live in a reading silo. They're searchable alongside your notes, saved articles, podcast notes, and everything else. A book highlight connects to the article that explored the same idea and the podcast episode where someone discussed the same concept. The reading informs everything else you know.

Organised by theme, not by book

Smart organization groups highlights by theme and topic, not just by which book they came from. All your highlights about leadership cluster together regardless of whether they came from a biography, a business book, or a psychology text. The organisation reflects what the ideas are about, not the container they were in.
