From 0.2 JPY per minuteFast transcription

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

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.

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.

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.

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

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.

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.

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.
