Never used for training
No art is stored for any training or testing purposes. Your frames are kept for one reason only: to save your animation, if you choose to.
Animate faster.
Draw only what matters.
Sketch your keyframes and TweenArt generates the in-betweens for you. Spend less time on tweening and more time bringing ideas to life.

Your drawings stay yours.
TweenArt is an animation tool designed to make animation production faster. While we use neural networks for freeform inbetweening, we don't use any stolen art or power-hungry models running on datacenters.
Inbetweening & Data
We own the entire training pipeline and use our own custom dataset to develop the inbetweening model. No art stolen at any stage.
No credit card needed
A username, email and password is the whole sign-up. We never ask for payment details, and there's no trial quietly counting down in the background.
