よくある質問
- How accurate is the AI transcription?
- 85-99% accuracy for clear audio in supported languages. Factors that affect accuracy: audio quality, background noise, heavy accents, multiple speakers, and technical vocabulary. For critical content, we recommend the human-reviewed option.
- What languages are supported?
- Over 99 languages including English, Spanish, Mandarin, French, German, Japanese, Korean, Arabic, Portuguese, Hindi, Italian, Dutch, Russian, Polish, Turkish, and many more. Auto-detect is available when you are not sure.
- What video formats can I upload?
- MP4, MOV, AVI, MKV, WebM, FLV, WMV — plus direct links to YouTube, TikTok, Vimeo, Dropbox, and Google Drive.

- Free tier: files up to 2 GB and 5 minutes of audio per upload. Signed-in users get 30 minutes per month. Pro users get 10 hours per month.
- Can I get timestamps in the output?
- Yes — word-level timestamps are included by default. You can export them embedded in SRT or VTT subtitle files, or in a plain text format with minute:second markers.
- Do you store my videos?
- Files are encrypted in transit and at rest, stored on enterprise-grade infrastructure (Cloudflare R2 and Neon Postgres), and automatically deleted within 24 hours of task completion. We never use your content to train AI models.
