From recording to transcript, AI minutes and subtitles
One file, as far as you want to take it: a transcript you can trust, minutes with receipts, a scored call review, subtitles translated into four more languages — or simply a clean DOCX.
Drop a file and watch it work
Up to 20 recordings at once, audio or video — up to 30 minutes each on Free, 3 hours on Starter, 6 on Pro and 10 on Studio. Each one reports the stage it is in and how much is left — no spinner that tells you nothing.
Fix a word, rename a speaker everywhere
Playback that highlights the line being spoken, inline editing of the text, and one click to move a line to the right speaker.
Minutes, action items, chapters — with receipts
Generate a document from one of six built-in kinds. Every item carries a clickable timestamp, so you can hear where it came from, and items that point to no moment in the recording are removed before you see it.
Scorecards for sales and support calls
Talk share, pace, longest monologue, interruptions and questions, plus a criterion-by-criterion scorecard with justification and the moment each one was met.
Subtitles checked before you download
SRT and WebVTT with readability rules, up to four translated languages per recording, and glossaries that keep names and jargon spelled your way.
Find any word — or ask a question — across all your recordings
Search every transcript in your account at once, or ask in your own words. Answers are built only from your transcripts, and every statement links to the moment it came from.
Example: a 70-minute PTA meeting
The PTA secretary records the meeting on a phone placed on the table (with the consent of everyone present). The recording is 70 minutes long, so it doesn’t fit the Free plan, where the limit is 30 minutes per file. On the Starter plan ($9 a month, files up to 3 hours) it looks like this:
SonaFact separates the voices automatically. You rename a speaker once, e.g. to “Chair”, and the name changes throughout the transcript. If the engine split one person into two, one command merges them, and a single remark can be moved to the right person.
The meeting minutes link every point to its moment in the recording. When someone asks “who volunteered to run the bake sale?”, click the point and listen. It works the same for a journalist checking an interview quote or a law firm going back to one sentence from a call.
A name the engine hears differently, e.g. “Shivon” instead of “Siobhan”, goes into the glossary as a “heard as” variant. In later recordings it is corrected automatically.
“Speaker 2” becomes a name
Speakers are separated automatically, and the line being spoken stays highlighted while you listen. When the engine gets one wrong, you move it to the right person in one click — or merge two speakers it split by mistake.
Every item links to the moment it was said
Minutes, action items, summaries, chapters and call reviews. Tap or hover an action item to see the sentence it came from. If the transcript doesn’t support an item, SonaFact removes it.
Participants, decisions, action items and a short summary.
Editable table: who, what, by when, and the moment it was agreed.
Time-stamped chapter list, ready to copy into a YouTube description.
Edit the built-in criteria or write your own, reusable across calls.
Review sales and support calls, not just read them
Talk share, pace, longest monologue, interruptions and questions — plus a scorecard you can edit to match your own process. Every criterion carries the justification and the moment it was met.
Sales & support use case →Checked before you download
SRT and WebVTT with readability rules: up to 42 characters per line and two lines per subtitle. Timing aims for 17 characters per second — subtitles are stretched into pauses or merged, and any still too fast are counted, with their moments listed so you can jump to them. Translate into up to four more languages and read every translated sentence next to the original, with uncertain ones marked.
Correct the transcript later and Update re-translates only the sentences that changed.

It tells you where it is unsure
Every automatic transcript has weak spots — a name said quickly, a word lost under a cough. Most tools hand you a clean-looking wall of text and let you find them yourself. SonaFact marks them.
Words the engine was not confident about carry a dotted underline. You proofread those, not the whole hour.
Each transcript states what share of its words were marked — usually a few percent on clear audio, more on a noisy phone call. It is measured on your file, not quoted from a brochure.
All one hundred languages go through the same engine and the same marking. A recording in Tamil gets its share of uncertain words stated just like one in English.
Try it on a recording you already have
The free plan is enough to judge accuracy, speaker separation and the editor.
