Frequently Asked Questions

How does the AI decide what makes a good Short?
It reads the full transcript and looks for self-contained moments with a hook — strong claims, stories, emotional peaks, punchlines. Clip boundaries snap to sentence starts and ends so nothing begins mid-thought.
Do the Shorts come with captions?
Yes — word-by-word animated captions in the bold style short-form video uses, burned into the video. Most Shorts are watched muted, so captions are the single biggest watch-time lever. You can toggle them off.
What video length works best?
Anything from a few minutes to a full podcast episode. Longer videos give the AI more moments to choose from; a 30-minute episode typically yields excellent picks.
