Introducing KeyFast

  • Staggering
    Quickly stagger layers or keyframes.
  • Easing
    KeyFast applies animations with easing applied by default.
  • Aligning Keyframes
    Select keyframes across several layers.
    Then click to align keyframes to your playhead. 
  • Overshoot animations
    Add overshoot to rotation, position, scale.
  • Staying in flow
    Keyfast helps you flow through tedious parts of animation.
    Allowing you to focus on the important bits only.

Why does KeyFast exist?

I've spent a lot of time making explainer videos. Simple, repetitive, explainer videos.
Eventually I started thinking, "how can I do the tedious parts faster?" And that's how KeyFast was born.

Using KeyFast made me realize how many hours I'd been leaving on the table... And it's a lot of hours!


Who is KeyFast for?

KeyFast is for anyone who uses After Effects and wants to work more efficiently. I seriously believe that! I've used KeyFast on high & low end projects. I use it on nearly every project I work on, and it saves me a lot of time, and (more importantly) boredom.


Still on the fence?

No problem, you can have KeyFast free for a week! (no strings attached, no subscription payment traps, etc.)

Try it on your next project, and if you don't like it, don't buy it. 0% risk. 100% likely that you'll save time.
