It’s called Krita. Maybe you’ve heard of it, but in case you haven’t, seriously, check it out! It’s really nice!
The best way I can describe this program is that it’s a combination of Easy Paint Tool SAI and Photoshop. And the best part is the program is completely free to download from their website. I think what I like most about it is that not only does it have a Stablizer like SAI does, but it has practically all the tools I ever use from Photoshop. Not saying it’s going to replace SAI or PS for me (at least not yet; I’m still learning my way around Krita lol), but it’s probably the only thing I’ve ever found that is coming close to doing it.
