Zartschool is an online art school founded by painting instructor Tatiana Zubova, offering flexible learning for beginners and more experienced artists. Its video-based lessons cover painting in oil and acrylic, digital graphics, art history, and composition. Students can choose from individual masterclasses focused on completing a specific artwork, multi-session courses on subjects such as portraits, landscapes, and palette-knife techniques, or express courses devoted to a narrower topic. The school advertises more than 200 lessons and courses, with examples including still lifes, flowers, water, and winter scenes.

Lessons are designed to show the painting process clearly, including the canvas and palette, and recordings are available after live sessions for students who cannot attend. Learning is accessible from anywhere with an internet-connected device. Zartschool also holds free events each month for different skill levels and invites visitors to subscribe for updates. New registrants are offered six free masterclasses. The website provides course listings, a schedule of upcoming online classes, a student gallery, and a personal account area.
