Beautiful and feature-rich shouldn't mean closed source
Free but not feature-less
Brushes, transforms, selections, filters, and even your Photoshop plugins work in Schist. Pull in your Affinity or Photoshop files with no issues!
Let your agents do the work!
If you have Codex or Claude Code installed with an active subscription, your agents can work alongside you editing the canvas as you watch!
Works great on Linux
Free and open source, the tool is fully built to run on modern Linux distributions! Loads in under 2 seconds on any platform!
Photoshop-class filters
134 filters from Photoshop's Filter menu, Filter Gallery and Neural Filters included, with the dialogs you already know. Every one previews live on the canvas, and the heavy sweeps run on your GPU!
