For artists who use AI
as a brush, not a substitute
ZSky AI is a tool independent artists use to extend their craft. Mood boards, color studies, reference generation, previs, ideation. Made by a photographer who needed a sketching tool he could afford. Free, no watermark, no signup, full commercial use.

The "AI slop" backlash is real. The 250,000-member anti-slop Facebook group is right to be angry at brands that use AI to cut creative corners. Marvel banned AI submissions. Comic-Con followed. Merriam-Webster named "slop" the 2025 word of the year. The artists yelling about AI slop are right about the slop.
They are also wrong about the brush. AI is not the painter. AI is the brush. The slop comes from the painter, not the tool. ZSky exists for the artists who know that difference and refuse to make slop with it.
Every output on ZSky is initiated by a human. Every image has a creator. Every credit goes back into supporting creators who can't afford other tools. We are not the tool that replaces you. We are the tool that lets you sketch faster than you ever could with a pencil, so you can iterate on your real work in your real medium.
How working artists actually use ZSky
- Mood boards — generate 20 visual references in 40 seconds for a project you're pitching
- Color studies — explore 10 palette variations of the same scene before you commit a single brushstroke
- Reference generation — pose references, lighting references, anatomy references for a figure you're drawing
- Previs & ideation — block out a complex scene before you spend a week painting it
- Composition exploration — try 12 framings of the same subject in 25 seconds
- Sketching & thumbnail generation — rapid iteration on initial concepts before committing to a final medium
- Fast video b-roll — generate 15-second clips for your portfolio reel without renting a camera
- Concept art for longer projects — fast iteration on character, environment, prop concepts
If you're using ZSky as the final output, that's also fine. We don't gatekeep. But most of our serious users treat it as a sketching and exploration tool, not as a delivery tool. That's how we designed it.
What you keep
You keep the copyright on every output. You keep the right to sell, license, exhibit, modify, or destroy your work. You keep your prompts (we don't share them with anyone). You keep your work even after you cancel your account.
You also keep the choice to use ZSky as a brush — not as a painter. We will never market your outputs as "AI generated" without your consent. We will never feature your work without asking. We will never take credit for what you make. The work is yours. The tool is just the tool.
What artists ask
Do I retain ownership of what I make on ZSky?
Yes, completely. You own the copyright on every output. ZSky claims no ownership, no usage rights, no licensing claim. You can sell it, exhibit it, license it, or destroy it. It is yours.
Does ZSky train on my prompts or outputs?
No. ZSky does not train on user prompts, user-uploaded reference images, or generation outputs. Your work stays yours.
Can I use ZSky outputs commercially?
Yes, on every plan including the free tier. There is no separate commercial license. Sell prints, license stock, build a portfolio, ship products. ZSky never claims a cut.
Is ZSky watermark-free?
Yes, on every plan including the free tier. We never add a watermark to your outputs.
What about image-to-image with my own reference?
Yes — upload your own reference image and transform it with text prompts. Costs 2 credits per generation. We don't store the reference after the generation completes.
I want to use ZSky as a sketching tool, not a final-output tool. Is that supported?
That is exactly how most working artists use ZSky. Mood boards, color studies, reference generation, previs. Many of our power users finish their work in Procreate, Photoshop, or analog media.
