Comfy-Canvas v1.0 places a complete painting and editing workspace directly inside ComfyUI. The tool removes the need for extra browser tabs by running a built-in overlay for masks, brushes, and live preview windows.

Core features for iterative editing

Persistent session tracking links every edit to a specific workspace node.
Non-destructive masks use simple black and white painting to hide image areas.
Standard painting and selection tools include adjustable size, opacity, and softness controls.
A dedicated text dock saves prompt history and triggers generation runs with one click.
Continuous autosaving protects your layer stack during active design work.

Teams building complex visual pipelines can test changes and generate fresh outputs without jumping between different programs. The steady revision cycle keeps all assets neatly grouped under one project folder.
