Audiobook proofing for publishers
Every word of the audio checked against the manuscript. One page of amendments with timestamps on them, not four hundred lines of noise. The first hour is free and no card is needed.
NO CARD · REPORT IN MINUTESThe engine finds hundreds of differences between the audio and the book. Almost none of them are faults. Handing a proofer all of them is how a tool gets abandoned, so we rank them and hand over the ones worth a minute of a person’s time. Everything else stays one click away.

The final PDF, EPUB or text. The book is the truth.
Listen, confirm or dismiss, export the sheet your client expects.
Wrong words, skipped lines, retakes, mouth noise, harsh esses. Each one timestamped.
Every finding plays from two seconds before it happens. Confirm or dismiss, move on.
File number, time, chapter, page, problem. The format publishers already use.
Six books a month to ninety, metered by the hour, priced to fall as you grow.
The book is read page-aware. Running heads, page numbers and footnote markers are stripped before they can become false alarms.
Every track becomes text with a timestamp on every single word.
Each track finds its own span of the book. No manual splitting.
The audio is matched to the manuscript word by word. A fourteen-hour book aligns in seconds.
"1,847" read as "eighteen forty-seven" is not an error. "death" read as "debt" is. Only the second kind survives.
What remains is written the way a human proofer would write it, with the audio one click away.
Proofing tools are sold by the finished hour. Here is what the money actually buys, using published prices. Check it yourself.

Pozotron pricing from pozotron.com/pricing, September 2026, billed in US dollars. A finished hour is an hour of delivered audio. We meter a book as ten finished hours. Prices change; the arithmetic is the point.
Every account starts with a free hour. A book is metered as ten finished hours. The price per book only falls as you grow, and stacking smaller accounts is never cheaper than the tier that fits.

Just the one book? Pay as you go at £6 a finished hour, or a ten-hour pack for £60. The first hour is free either way, and no card is needed to try it.
No. It does the first pass, hearing every word against the manuscript, and hands you a short list to confirm or dismiss. The judgment stays yours. Anyone claiming a machine catches everything has not proofed a book.
On a real fourteen-hour production it produced a fifteen-line report containing the faults a professional proofer found by ear. It will not catch everything, and it will occasionally flag something that turns out to be fine, which is why every finding has a listen button and an accept or decline.
The delivery folder of audio tracks and the final manuscript as PDF, EPUB or plain text. Nothing needs splitting or renaming. Each track finds its own place in the book.
Minutes, not days. A full-length book is usually proofed while you make coffee.
The manuscript never leaves our servers. Everything is encrypted at rest, you choose how long we keep the audio, and titles marked Confidential are never sent to any outside service. See the security page for the detail.
A printable report, a CSV, and the publisher sheet format of file number, time, chapter, page and problem. The page numbers come from your actual PDF.
Pay as you go at six pounds a finished hour, or a ten-hour pack for sixty. No subscription, and the first hour is free. Solo starts at £89 a month when the work becomes regular.
The first hour is free, no card, and the report comes back while you make coffee. If it does not find what your proofer finds, you have lost ten minutes.
