Totally! The basic features of the app are free, and you can use it for anything you'd like, including commercial work. Part of our mission is to bring the art community together and make sure all the artists (and aspiring artists, too!) around the world have equal access to professional art tools, regardless of their origin, location, device, or financial situation.
If you need more advanced drawing & collaborative features, you can upgrade to Blaze plan, which is a great choice for aspiring and professional artists.
We also have paid Professional and Enterprise plans which are geared towards professional usage of teams and studios, and focus on advanced collaborative features (version control, comments, approvals) and privacy of the artworks (private data, access control).
