Why use MKV to Text?
Built for MKV video
MKV files come from the open Matroska video container. Our pipeline decodes them directly. No manual conversion to MP3 needed first.
99% accuracy
Our premium engine handles accents, overlapping speech, and noisy recordings.
99+ languages auto-detected
Spanish, French, Arabic, Mandarin, Wolof, Swahili. You don't pick the language, we detect it from the audio.
Speakers, timestamps, summary
Clickable timestamps, speaker detection and an AI summary with action items and an email draft.
How it works
Upload your MKV file
Drag & drop your .mkv file, or paste a URL. First 30 minutes free; paid plans process the full file.
AI transcribes it
Our AI pipeline handles MKV video natively. Typical 1-hour file finishes in 2-4 minutes.
Export, edit, share
Download TXT free, or export SRT, VTT and JSON with paid plans, the Weekly Pass or your first file. Edit in the browser and rename speakers.
