Frequently asked questions

How do I use the free minutes?

On your first login after registration, you receive 100 minutes of free transcription. Upload audio or video files and download the resulting text.

What languages are supported and how accurate is the transcription?

We support approximately 100 languages with automatic language detection. Using Whisper large-v3 Turbo, benchmark estimates indicate roughly 97% accuracy for English and 92% for Japanese. Accuracy varies with recording conditions and speaker clarity. Background noise increases errors, so use clear audio when possible.

What happens to unused minutes?

As long as your paid subscription stays active, unused minutes roll over automatically. They expire if the subscription ends. Free minutes are valid for one month from registration, and they also roll over if you start a paid plan within that month.

Is my data handled securely?

Generated transcripts are stored securely and can be deleted anytime from the dashboard. Uploaded audio or video files are automatically deleted after transcription and are never shared with third parties.

Can I leave the site while transcription is running?

Yes. Transcription continues on the server, and when it finishes you can view the result from "History" on the dashboard.

How do you calculate fractional time?

We round up in one-minute units (minimum 5 minutes). When you transcribe multiple files together, we calculate on the combined length, so uploading in batches is more economical. Up to 20 files can be processed at once.

Which file formats can I receive?

You can download in 5 formats: JSON, TXT, SRT, VTT, and plain TXT (without timestamps). Inputs support common audio and video files up to 5 GB and 10 hours total per upload.

What payment methods are available?

Payments are handled via Stripe, and you can pay with credit card, Apple Pay, Google Pay, or Link. After payment, Stripe automatically emails a receipt or invoice to your registered address. For purchase history or reissuing receipts, please refer to the Stripe email you received.

Is support available?

For requests, technical issues, or questions about how to use the service, please contact us through the inquiry form. We normally reply within one business day. We do not provide manual corrections of transcripts.
