Export Formats

Download your transcripts in any format you need. STT.ai supports six export formats, each optimized for different workflows.

How it works →
Client-side encryption on — your transcript will be encrypted in your browser before being stored. The server processes your audio for transcription, then the result is encrypted locally with your key before saving. (All data is always encrypted via HTTPS in transit.)
Speed varies by platform. Some transcripts are ready in seconds, others may take a few minutes depending on video length.

Which Format Should You Choose?

For subtitles and captions

Use SRT for maximum compatibility or VTT for web-based video players. SRT works with YouTube, Vimeo, Premiere Pro, Final Cut, and DaVinci Resolve.

For developers and integrations

Use JSON for the richest data including word-level timestamps, confidence scores, and speaker IDs. Ideal for building custom applications.

For quick copy-paste

Use TXT for a simple plain text transcript you can paste anywhere -- emails, notes, chat, or any text field.
