ExplainCut

ExplainCut turns a plain talking-head video into a whiteboard-style explainer. Upload a 15–60 second clip of yourself talking, and it transcribes your speech, figures out the empty space around you in frame, plans a diagram timed to your words, draws it as a hand-drawn sketch (wobbly strokes, a visible pen tip, hachure fills, handwritten captions), cuts you out of the original footage, and composites you in front of the diagram as it builds live — all without you writing a single line of script or touching a timeline. It also runs a self-review pass: an agent loop that watches the finished cut, flags timing or overlap problems, re-plans only the flagged scenes, re-renders, and verifies its own fixes before showing you a before/after.
