Free AI Transcription — Turn Audio & Video into Text
Upload a recording and let AI write it out for you, with an optional .SRT subtitle file to download.
What is Audio Transcription?
Cobain AI's Audio Transcription tool converts recordings into clean, readable text. Upload an audio or video file — mp3, wav, m4a, mp4, and more — and the AI writes out what was said, so you can read, search, and reuse it. Need captions? Export an .SRT subtitle file for your video in the same run.

Upload mp3, wav, m4a, mp4, and other everyday audio and video formats.

Skip manual transcription — let the AI handle the first pass so you only need to tidy it up.

Frequently asked questions
Is the transcription tool free?
Yes. You can start transcribing for free with a Cobain AI account, with paid options for higher volume.
What file formats can I upload?
You can upload common audio and video formats such as mp3, wav, m4a, and mp4.
Is there a file size or length limit?
Yes. To keep things fast and reliable, each file should be up to around 20MB or roughly 20-30 minutes. Split longer recordings into shorter parts.
Can I get subtitles for my video?
Yes. Alongside the plain transcript, you can export a timed .SRT subtitle file to add captions to your video.
Will the transcript be perfect?
It's very accurate on clear audio, but background noise, crosstalk, and heavy accents can cause slips — give the text a quick read before you publish it.
