HirayaAI
Turn a PDF you have the rights to into a natural-sounding MP3 you can listen to anywhere — free preview first, one-time payment, no account.
PDFs are made for pages, not for listening — read aloud naively they're full of page numbers, running headers and figure labels. HirayaAI extracts the actual text from your PDF and cleans it for narration: page artifacts are stripped, broken lines are joined back into sentences and paragraph breaks become natural pauses. What you get is a single MP3 audiobook that sounds like it was read from a book, not from a printout.
It works for far more than books: reports, research papers, study material, manuals and manuscripts all convert the same way. Upload the PDF, pick a voice and hear a free preview of the opening in seconds — generated from your actual file — before paying anything.

Your PDF needs selectable text. If you can highlight and copy text in your PDF reader, it will convert. Scanned or image-only PDFs — photos of pages — contain no extractable text and won't work. The free preview makes this a no-risk check: if the text extracted badly, you'll hear it before paying a cent.
Narration is cleaned, not read verbatim. Page numbers, repeated headers and footers, and figure references like "Fig. 3.1" are removed so the audio flows like a narrated book. Long documents are split into sections automatically when there are no clear chapter headings.
