DUIK 15 in development

After the success of the crowdfunding campaign, Duik 15 is currently in development, and will probably be released this summer!
Thank you for your support.
More info on the page of the project.

 Icone 14

Second update, 14.23 available!

Bringing some upgrades to existing tools and bugfixes, the second update to the most successful version of Duik is now available!

apercu ik

Inverse Kinematics (IK)

This tool is essential in many cases – to animate a character, especially for a walk, a run; to animate mechanical processes of any kind, etc. – inverse kinematics implied the use of very complex trigonometrical expressions in After Effects (see Dan Ebberts‘s expressions). Duik automates this creation process to allow you to focus on the animation! A simple controller at the end of an arm, of a leg, or on the shoulders, an IK that you created in one clic, now you can animate the entire limb just by modifying the position of the hand or the foot!

apercu bones

Bones and puppet tool

Bones are layers which replace puppet pins in After Effects. Created in a single click, they can be parented and be controlled by IK’s. You can reproduce the exact same methods like for the rigging of characters in 3D, but in After Effects. The puppet acts like with skinning, and Duik fills out the setup!

apercu autorig


Most of the characters are alike… Arms, Legs, Head… To avoid repeating the same work again and again, Duik’s Autorig can automatically rig a biped character! You only have to move the anchor points to the appropriate joints (or create bones if you use a puppet)and the Autorig does the job: controllers, parenting, IK’s, expressions…
And because anyone is unique, the Autorig adapts to your character: wether it has only one arm, or it’s legs don’t have knees, it doesn’t matter, the rig is automaticaly adapted.

apercu setup

Rigging tools

In addition to main rigging tools (IK, Bones, Autorig), Duik has many other advanced tools, to control layers, ease expressions creation…

Now well trained users as well as the ones skilled in 3D can create characters’ rigging in After Effects and reproduce the principles that are used in 3D, combining IK, links and expressions…

apercu anim

Animation tools

It’s one thing to have well rigged characters, now you have to animate them easily! Duik brings all kinds of animation controllers, from the powerful Spring, which automates delays and bounces of an object,to the Wheel, which automates the rotation of the layer while it translates.
Among those tools, now you can copy/paste an animation from several layers at once very easily, into the same comp to repeat the animation, or from a comp to another to reuse it.
There is also an very simple interface to manage interpolations to animate very easily without manipulating curves.



Duik was created because it was needed in some animation productions, and now it’s done, let’s share it!
Duik is completely free, and will stay free, for any purpose. You can download it, use it, share it, modify it, as much as you want!
Being free, Duik became a must-have to animate on After Effects, used worldwide, downloaded more than 100 000 times since its first release in 2009. And this won’t change! Even being a great success, Duik won’t be sold. Let’s share techniques and knowledge!

So, Duik is free software licensed under GNU-GPL v3.

If you want to help development, so it can continue to evolve, and hep maitain this website up, you can donate the amount of your choice.



Duik is and will stay free.
If, in your opinion, Duik deserves to be paid for, you can buy it for the price of your choice, for the price you think is fair.
