Pixanima is a free, browser-based pixel-art & animation studio — no install. Draw with layers, effects and palettes, animate on a frame timeline with onion-skin, and export to GIF, sprite sheets or PNG. What's different: a built-in AI assistant on the canvas — a text prompt generates sprites, seamless tiles and palettes, re-poses your character, or creates AI in-between frames for animation. The editor is 100% free; only AI uses prepaid credits, and new accounts get free credits.
