FAQ

Frequently Asked Questions

Everything you need to know about converting audio to text with VoiceScribe AI.

Is VoiceScribe AI really free to convert audio to text?

Yes. Every account includes free monthly transcription minutes — no credit card required to start. You can transcribe MP3, MP4, WAV and other common formats without paying. Paid plans only unlock longer files, priority processing and advanced exports.

What audio and video formats can I transcribe?

VoiceScribe AI supports MP3, MP4, WAV, M4A, AAC, FLAC, OGG, WEBM, MOV, AVI and MKV. If your file plays in a browser or media player, we can almost certainly transcribe it.

How accurate is the AI transcription?

For clear English audio recorded in a quiet environment, accuracy typically exceeds 95%. Accuracy depends on audio quality, accents and background noise. We use state-of-the-art speech recognition models updated regularly.

Is my uploaded audio kept private?

Yes. Files are encrypted in transit and at rest. They are processed only to generate your transcript and are never used to train public models or shared with third parties. You can delete files and transcripts at any time from your dashboard.

How is this different from Otter.ai, Rev or Trint?

VoiceScribe AI focuses on a fast, no-friction "drop file → get transcript" workflow with generous free quotas. Compared to Otter, we support more file formats and languages out of the box; compared to Rev, our automatic transcripts are instant and free; compared to Trint, our pricing scales more gently for individuals and small teams.
