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.

No made-up answers

ChatGPT makes up quotes. Other tools rewrite what the author said.
Every quote here is copied straight from your source. If we can't find the exact words, we don't show the quote — ever.

See the whole picture

A long PDF or video hides its structure. You finish it not knowing how the pieces fit.
We build a clickable map of the key ideas. See the shape of the whole thing in one screen, then click into anything that catches your eye.

Ask the source anything

Re-reading is slow. Search shows you lines, not real answers. Your notes go cold.
Chat with the source like it's a person. Every answer cites the page or timestamp — one click and you're at the exact spot.

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.

The method scales linearly across all benchmarks 0407

VERIFIED · p.42

“…scales linearly with input size across all three benchmarks…”

Substring match confirmed

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.

What does the paper actually argue?
Three claims, with citations:Linear scaling 04, memory bottleneck above 10k tokens 07...

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.

[00:42] “…the key insight is that…”

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.

  1. 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.

  2. 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.

  3. 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.

  4. 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.
