Mindly's summary plus your highlights gets you 80% back into a book in 5 minutes.
Book Summaries
A Personal Library of Books, Notes, and the Ideas Behind Them
Save book PDFs, your highlights, your reactions, and Mindly's AI summary of each. Your reading actually compounds instead of disappearing onto the shelf.
How it works
How Mindly builds a reading library
- Save a book PDF, EPUB, or just a list of highlights via ⌘M. Add a one-line reaction or quote of your own.
- Mindly generates a structured summary: main argument, key chapters, surprising claims, your highlights pulled out.
- AI tags by theme automatically: "stoicism", "design", "negotiation". Every book that touches an idea is findable in one search.
- Use the mind map to see how books connect across themes. Books read years apart cluster around shared ideas.
When to use it
Why a book library matters
Cross-book themes
Two books say the same thing in different ways. The mind map surfaces the overlap.
Writing references
Pulling a quote into an essay: search by the idea, not the book name.
Reading list management
Currently reading, next up, finished, abandoned. All tagged automatically.
A reading journal that keeps itself
Your reactions, captured as you read by voice or a quick line, become a dated, searchable record of what each book actually did to your thinking.
Non-fiction you actually apply
The advice book only pays off if the idea resurfaces at the moment it applies. Search by the problem you are facing and the relevant chapter notes come back.
Why it works
What makes reading actually stick
Every book leaves a record
Most books evaporate within a month of finishing them. Capture your highlights, a photo of a passage, or a spoken reaction as you read, and Mindly turns each one into a summarized, tagged item, so every book leaves behind something you can actually use.
Summaries that make review possible
Rereading a book to recover one idea is not realistic. Mindly summarizes long saves automatically, so revisiting a book takes minutes: scan the summary, jump to the passages that mattered, and the argument comes back.
Themes across books surface on their own
The real payoff of reading is the connection between books. Mindly links related saves, so the psychology book from January and the biography from June turn out to share a theme, and the mind map shows it before you would have noticed yourself.
Ask your books questions
Open a saved book note or PDF and chat with it. Ask what the author argued about a topic or pull the key points, with answers grounded in what you saved, so checking a half-remembered claim takes a moment.
Why it matters
Why your books deserve a real library
Most people read 30 books a year and remember 3. Not because the books were bad, but because nothing structured connects what you read to what you do. A real library of book summaries, tagged and linked, turns reading from entertainment into infrastructure.
Common questions
Book summaries FAQ
How do I get my highlights into Mindly?
Capture them as you read: photograph a page from a physical book and Mindly reads the text inside, paste digital highlights, or record a voice reaction. Readwise integration also pulls in your existing highlights, and everything gets summarized and tagged automatically.
Can Mindly summarize a whole book?
Mindly summarizes what you save: your highlights, chapter notes, or a PDF of the book. Long saves get an automatic summary, so the material you captured becomes scannable, and the summary is grounded in your copy rather than a generic internet synopsis.
How do I remember what I read months ago?
Search for the idea in plain language and the book note surfaces by meaning, with its summary and related saves alongside. Retrieval, not rereading, is how a reading library pays back, and it is the part Mindly automates.
Do connections between books really appear?
Yes. Mindly compares each save against your library semantically and links related items, so books sharing a theme cluster together on the mind map even when they use different vocabulary. The cross-book patterns are usually the most valuable thing in the library.
How do I take notes on books I read?
Capture as you read, in whatever form is fastest: photograph the passage, type one line of reaction, or speak a voice memo at the end of a chapter. Mindly turns each capture into a summarized, tagged item, so the notes accumulate without a ritual. The mistake to avoid is saving nothing while reading and hoping to write it all up later, because later never comes.
What is the best book notes app for Mac?
The best book notes app is the one that makes the notes retrievable years later. On macOS, Mindly reads everything you capture (including photographed pages), summarizes and tags it by theme, connects related books, and lets you search by meaning or chat with your notes. Readwise integration pulls in existing highlights, so your history comes with you.
How many books can I keep on the free tier?
The free tier supports up to 25 items and Mindly Pro removes the limit. A reading library grows for years, so Pro is the natural fit once the habit sticks. If you stop using Pro, items beyond the free limit become read only rather than deleted, and you can always export.
