Stop highlighting.
Start mapping.
Drop in a PDF, podcast, YouTube video, or any web page. We turn it into a clickable mind map and a chat that quotes the source word-for-word. No made-up answers, ever.

Why PaperMind
Reading is broken. We fixed it.
Long PDFs you never finish. Chatbots that make things up. Summaries that miss the point. Bookmarks you forget about. PaperMind fixes all of that — and shows you the source for every answer.

The features
Every superpower your reading has been missing.
Interactive mind maps
See any document in one screen
Zoom in, zoom out, click anywhere to expand. A 500-page book fits on one map, and every dot points back to the exact passage that backs it.
VERIFIED · p.42
“…scales linearly with input size across all three benchmarks…”
Real quotes only
Word-for-word, every time
We compare every quote against your source before we show it. If the exact words aren't there, we drop the quote. You never see a made-up answer.
Smart chat
Ask in your own words
You don't have to phrase things like the author did. The chat finds the right passage by meaning, streams the answer back, and shows you exactly where it came from.
Six formats
Drop in almost anything
PDFs, EPUB books, Word docs, YouTube videos, podcasts, and web articles all work the same way — one upload, one map.
Audio & video
Podcasts and videos, searchable
We transcribe with timestamps. Click any idea on the map and the player jumps to the exact second where it was said.
Share & export
Take your work anywhere
Get a public link to share, download the map as Markdown, or grab the full transcript with page numbers and timestamps baked in.
Source coverage
If you read it, we map it.
Most tools only handle PDFs. PaperMind handles six formats the same way, and figures out which one a URL is the moment you paste it in.

How it works
From source to insight in four steps.
- 01
Drop in your source
Upload a file or paste a link. We figure out what kind it is — PDF, podcast, video, web page — and start the rest automatically.
- 02
We read it carefully
We pull out the clean text (or a transcript, for audio and video), break it into bite-sized pieces, and index every one so you can search by meaning.
- 03
We build the map
Our model reads every section, draws a small map of the key ideas, then stitches them into one big hierarchy you can zoom and click through.
- 04
Every quote is checked
Before any quote lands on the map, we make sure it actually exists in your source — word for word. If it doesn't match, we drop it.
How we compare
One tool. All the wins.
Other tools do one part well. PaperMind does the whole flow — and double-checks every quote before you see it.
