Read Any PDF Aloud
Turn dense PDFs into audio and listen while word highlighting follows along.
unChonk reads PDFs out loud right in your browser with natural AI voices and real-time word highlighting — so you can get through reports, papers, and documents with your ears instead of your eyes.
Listen to PDFs instead of staring at them
PDFs are where the longest, densest reading tends to live — research papers, manuals, contracts, textbooks, reports. Reading them on screen is slow and tiring, and it's easy to lose your place in a wall of text. Listening changes that. When a natural voice reads the document to you, you can absorb it while your eyes rest, or follow along visually as each word is highlighted.
unChonk reads the PDF out loud directly in your browser. There's no converting to another format and no copy-pasting page by page — open the document and press play. You control the speed, so you can slow down for the hard parts and speed up through the rest.
The result is a faster, lower-effort way to get through PDFs: less eye strain, better focus, and more of your attention on the content.
