Stewdio

Stewdio is a desktop application for Mac, built for Apple Silicon, that makes motion graphics from prompts. The user describes an animation, optionally supplying reference images, videos or code, and the app generates it as an editable composition. The vendor frames it as a replacement for hours of tutorials and manual work in After Effects. The generated result is not a flat render. Stewdio gives studio style controls: a timeline of compositions, sequences and layers, keyframes on any property with easing presets or custom curves, a default set of position, size, scale, rotation and opacity on every layer, and sliders created automatically from the parameters a generated script exposes. That lets a designer adjust the look without touching code. The showreel on the home page includes 4K transitions and generative effects built this way. Stewdio does not bill for model use. The vendor says users bring their own model subscriptions, with existing Claude or OpenAI plans powering generation, so there is no separate charge for language model inference. It is aimed at motion designers, video editors and developers who want faster animation work with fine control. The site publishes no pricing page, so the cost of the application itself is not stated.
