HOW IT WORKS

Three steps you don't have to take

You paste a link. Everything below happens automatically, in one pass.

01

Transcribed

The strongest speech model, run end-to-end on the full audio. No chunking artifacts at speaker boundaries.

02

Diarized

Speaker turns detected at every change of voice and labeled with names you can edit right in your dashboard.

03

Cleaned

Punctuation, casing, and brand-name corrections, with merge-on-rename. Clean enough to publish as-is.

SEE IT IN ACTION

Watch a transcript come together

Paste a link and the speaker-labeled transcript builds itself: names, timestamps, and clean, publish-ready copy in a couple of minutes.

Just add txt to any video URL

FOR HUMANS & AGENTS

Drop it into your pipeline.

A plain REST API that turns any link into a clean, speaker-labeled transcript. One call your pipeline or agent can drive.

Web Interface

Paste. Process. Perfect.

Paste any YouTube, X, Instagram, or TikTok link and get speaker-labeled transcripts in JSON, TXT, SRT, or VTT, ready in minutes.
