An After Effects alternative that sets the keyframes for you
Kario is an AI motion graphics agent with an editor built on the ideas you know from After Effects: compositions, layers, nulls, keyframes, easing curves, track mattes, trim paths and a camera. The difference is who does the keyframing. You write a brief, Kario builds the comp, and you edit it the way you would in After Effects, or by describing the change.
Below, Kario builds a title shot for Corvane Arc headphones, then it's edited three ways: by dragging on the timeline, in a keyframe's curve, and with a note in chat.

The comp behind the shot
- The finished shot first: a camera push, a focus pull, three callouts drawn off a null, and a title rising through a track matte.
- Then the comp in Kario Studio: Camera, Title, Matte, Null – callouts and Product on the timeline, each with its keyframes.
- The Title’s clip is dragged 0.6 seconds later, so it lands after the callouts.
- Its first Position keyframe gets a heavier ease-out, by pulling the curve’s out handle.
- A note in chat, “Widen the shot so the battery label stays in”, rewrites only the camera’s keyframes: the push now ends at 1.05× instead of 1.18×.
