FAQ
Questions, answered plainly.
Including the ones with awkward answers — where accuracy drops, what the fair-use clause actually means, and who is responsible for recording consent.
Getting started
Do I need to install anything?
No. Everything runs in the browser — upload a file and download the result. There is nothing to install and no plugin to keep updated.
What file formats can I upload?
Every common audio and video format: MP3, WAV, M4A, AAC, FLAC, OGG, Opus, WMA, AMR, MP4, MOV, MKV, WebM, AVI, and more. You do not need to convert anything first.
How long does it take?
Usually a fraction of the recording length — a one-hour meeting typically comes back in a few minutes. Very long files and heavy load can take longer.
Do I need a credit card to try it?
No. The free plan gives you 60 minutes every month with no card and no trial countdown.
Accuracy and languages
How accurate is it really?
Around 99% on clear recordings — decent microphone, one person speaking at a time. Background noise, strong accents, and people talking over each other bring that down, as they do for every engine. Use the free minutes to measure it on your own audio.
Which languages do you support?
99 languages, detected automatically. Recordings that switch language mid-sentence are handled too.
Can it tell speakers apart?
Yes — up to 6 speakers, labelled automatically. You rename the labels once and the change flows through the transcript and every export. Heavy crosstalk is the hard case: expect labels to blur where people talk over each other.
Does it handle technical or medical vocabulary?
Specialist terminology generally transcribes better than people expect, but always review the first few minutes of an important file before trusting the rest.
Plans and billing
What does "unlimited" mean?
Unlimited transcription minutes on any paid plan. A fair-use clause in the terms prevents abuse at extreme volume — reselling tens of thousands of hours, for instance. Normal professional use, however heavy, is not affected, and we contact you before taking any action.
Can I pay without a subscription?
Yes. Pay-as-you-go starts at $0.10 per minute with no commitment. Packs bring it to $0.075, and top-ups on an active plan are $0.07.
What happens if I cancel?
You keep access until the end of the period you already paid for, and your transcripts remain available to export. Nothing is deleted the moment a payment stops.
Do you issue VAT invoices?
Yes. Payments go through a merchant of record, so EU VAT is handled and you receive a proper invoice.
Privacy and security
Do you use my recordings to train models?
No — on any plan, including the free one. Your audio and transcripts are never used as training data.
Where is my data stored?
In the EU, under GDPR. A Data Processing Agreement is available for organisations that need one.
Can I delete my data?
Yes. Delete an individual file or your whole account, and the data goes with it, source recordings included.
Is it legal to record my meetings?
That depends on where you and the other participants are. Many jurisdictions require everyone to be informed, and some require explicit consent. Our meeting bot appears in the participant list deliberately, but obtaining consent is your responsibility.
