What’s in it

Reaction videos, a keystroke away.

Everything between having the thought and posting it, without the editing session in between.

Work on any media you want. Paste a link and it’s a project: the video, its transcript, and everything you say about it, in one place.

Transcript

T

Edit with words, not power tools. Every word sits under the video, in time. Select a sentence and that’s your clip.

C

Clip anything you find interesting, provocative, or plain wrong. Drag across the bar or pick a line. No take needed; the moment can speak for itself.

R

Press R while it plays and say your piece. When you press it again, the clip is already cut to what you were watching and your take is on it: beside it, stacked, in the corner, or full frame. Captions on. Nothing to edit.
