Before you upload

Audio to text: what to expect

VoiceScribe AI converts speech from uploaded audio or video into a transcript you can review and export. The public uploader can be tried without registering; it is not an unlimited free service.

Free allowance
The default free allowance is 3 transcription tasks per day, with local audio/video uploads automatically previewing the first 30 seconds. Files of 30 seconds or less are transcribed in full. Copying, editing, exports, GPT and translation are available to everyone for accessible transcript content. Full transcription beyond the preview requires Pro. Your available quota is determined by the service.
File size and processing
The uploader accepts files up to 6 GiB (6,442,450,944 bytes). Browser memory and service limits may be lower. Processing time is not guaranteed.
Review and export
Review names, numbers and speaker labels. TXT, DOCX, SRT and VTT support multilingual text. PDF supports Latin, Cyrillic, Greek, Chinese, Japanese and Korean text; use Word (DOCX) if PDF is unavailable. The upload workflow opens the task detail page; wait for processing to finish before reviewing and exporting the full result.
When this is not a fit
For recorded speech, not a human transcription or proofreading service. Background noise, overlapping speakers and unfamiliar names can introduce errors.

Audio is uploaded for processing, not transcribed entirely offline. Before uploading sensitive recordings, review our privacy policy and ask about retention and deletion. See current paid plan terms before subscribing.

Built for audio, video, meetings, podcasts, lectures and interviews.

TXT, DOCX, SRT, VTT for all languages. PDF (basic ASCII only) for plain English text.
