Frequently asked questions
Is there really a free preview? ▾
Yes. Upload any file and you get the first 2 minutes transcribed and shown as a live WebVTT preview for free — no account, no card required. You only pay when you unlock the full project export.
How much does a full export cost? ▾
A single full project export is $1.50, or 1 credit. Credit packs (3 and 10 exports) bring the per-export price down. There are no subscriptions — you pay as you go.
Do I need to create an account? ▾
No. You can upload, preview and pay for a single export with zero registration. A free account is optional — it only adds a credit balance and download history for repeat use.
What formats do I get? ▾
Every unlock downloads all four: .vtt (WebVTT), .srt (SubRip), .txt (plain text) and .md (Markdown). WebVTT works natively in HTML5 <video> and YouTube; SRT is the interchange standard for editors and encoders.
Which files are supported? ▾
Audio: MP3, M4A, WAV, OGG, FLAC, AAC. Video containers: MP4, WebM, MOV (the audio track is extracted automatically). Files up to 500MB are accepted; long files are split and merged for you.
How long can my audio be? ▾
There is no hard cap on length. Whisper processes ~25 minutes per request, so longer files are automatically split at silence and joined back together with correct timing — a 1-hour podcast works fine.
What happens to my upload? ▾
Files are processed on the server and then deleted after export — we do not keep your audio or share it. See the privacy note on the home page.
How accurate is the transcription? ▾
We use OpenAI Whisper, one of the most accurate speech-to-text models, with automatic language detection and proper punctuation. For a full export you can review the sample first before paying.
Which languages are supported? ▾
Whisper supports 99+ languages with automatic detection. Subtitles are timestamped to match your video so they display inline as you play.
Are the timecodes accurate? ▾
Yes — every cue carries precise start/end millisecond timestamps (HH:MM:SS.mmm for VTT, HH:MM:SS,mmm for SRT), so captions stay in sync with your video or podcast.
