# Animate graphics by describing the motion

> Yes, the Tella Agent sets keyframes and easing in Tella Motion from a plain description of what moves, when, and how it should feel. It works on any property, such as position, scale, rotation or opacity. The keyframes stay editable like a hand edit, so you can keep asking for changes.

## Can an AI assistant set keyframes and easing so I don't have to animate by hand?

Yes, the [Tella Agent](https://www.tella.com/agent) sets keyframes and easing in [Tella Motion](https://www.tella.com/help/editing/tella-motion) from a plain description of what moves, when, and how it should feel. It works on any property, such as position, scale, rotation or opacity. The keyframes stay editable like a hand edit, so you can keep asking for changes.

## Prompt to start from

```text
In this Tella Motion clip, slide the title "Launch week" up 80 pixels and fade it in over the first 0.6 seconds with an ease-out. Hold until 3 seconds, then scale it to 90% and fade out over 0.4 seconds with an ease-in.

## Good to know

- Available to everyone: through the Tella Agent on a paid plan or the 7-day trial, or through Claude or ChatGPT on any plan.
- A Tella Motion clip has no layouts or cuts, but you can add overlays on top of it.
- Property values use the editor's units. Percentages are fractions, so opacity 0.5 means half.
- Tella Motion does not generate footage. AI video generation is a separate [Media Library](https://www.tella.com/help/editing/use-media) feature.
