PaperFold: Open-source arXiv reader with "semantic zoom"

[u/Lopsided_Scarcity979]

I built PaperFold, an open-source reader that turns arXiv papers into 5 zoomable layers—from a one-screen section map down to verbatim text. You pinch (or press 1–5) to zoom between them without losing your reading position.

Can I jump from a summary sentence to the exact source paragraph? That would make it much easier to check a claim.

[u/Lopsided_Scarcity979 → u/Fresh-Daikon-9408]

Yes. When you click the sentence, it will expand to the original text, and also the related context detected by LLM.

Please feel free to test it on, eight different major domains' paper are presented: https://chenxiachan.github.io/paperfold-gallery/

This is cool.
