What makes it different
Grain is rendered into the image at full resolution, not pasted on top, so it survives JPEG compression, scaling and print
Preview matches the 4K export exactly; what you tune on a laptop is what lands on the monitor
Pay once, never auto-renews; no subscription required
Free tier is genuinely useful with 5 full-resolution 4K exports monthly
Draws mathematical objects exactly as written on paper with natural notation
