DENSITY SEGMENTER

The only non-AI tool that maps timestamps based on actual speech volume.

Mark chapters with [Header Name] anywhere in your transcript.
Example: [00:00 Intro] or [The SEO Problem] — both work perfectly.
Headers: 0 Words: 0 Est. Read Time: 0 min ⚠ Enter transcript above
⏱ Start Offset: seconds  (use if you have a cold open / ad pre-roll)

The Density Algorithm

Instead of guessing, Rebrixe analyzes the character weight between your headers. This mirrors real-world speech pacing — longer sections get more time, shorter sections get less. No AI needed.

Instant YouTube Sync

Copy-paste the output directly into your YouTube Description to trigger automatic video chapters. The tool auto-validates that your first chapter starts at 0:00 — a YouTube requirement.

WPM-Aware Timing

Set your natural speaking speed and the segmenter cross-references it against text density to give you timestamps that actually match your recording — not just evenly-split guesses.

Works with Any Transcript

Paste raw transcripts from Otter.ai, Descript, Rev, or anything else. Just add [Chapter Headers] and hit Generate.
