Why I'm this generous
The questions I get asked most often, answered honestly. — Cemhan
Is the free tier really free forever?
+
Yes. Free forever means free forever. There is no trial clock, no hidden conversion step, no credit card required. Unlimited video and image generation, and no ads anywhere — free is funded by the paid tiers, not by advertising. Commercial use is allowed on free. The only differences from paid are: a small 'MADE WITH / zsky.ai' wordmark plate on free-tier output (both videos and images), and you share the standard queue during peak hours. That's it. I'm not going to pull the rug out from under anyone.
Why are you so generous?
+
Because I couldn't afford to pay for Midjourney or Runway when I needed them. I have aphantasia — I literally cannot picture images in my mind. A camera was the first thing that let me see my own ideas. After my TBI, creating was part of how I got my brain back. The idea that someone else would be locked out of that because they can't afford $20/month is the thing that made me build this. The free tier is the mission. The paid tiers are how I keep the mission running.
Can I cancel anytime?
+
Yes. One click in your account settings. You keep your paid tier until the end of your current billing period, then you automatically move back to the Free Forever plan — you don't lose your account, your creations, or your history. No cancellation fee, no "are you sure" funnel, no retention offers designed to trap you.
Is this safe — no hidden fees?
+
No hidden fees. The price on this page is the price. No setup fee, no per-generation surcharge, no "premium models" paywall buried in-app. Payments are processed by Stripe with 256-bit encryption. ZSky never sees your full card number. Refund window is 24 hours from your initial purchase — email [email protected] within 24 hours and we'll refund you, no questions asked. After that, your subscription runs through the end of the period you paid for and you can cancel anytime to stop the next renewal.
Why would I pay when free works?
+
Three honest reasons. (1) Instant generation on the dedicated RTX 5090 fleet, wordmark plate removed from downloads, longer videos, higher resolution, and (Ultra+) 4K with explicit commercial license. (2) Your creations are kept for as long as you subscribe — free-tier galleries roll off after 7 days. (3) If you believe in the mission, paying is how you literally keep the lights on for the next creator who can't afford anything. If none of those matter to you right now, please stay on Free. I built Free to be the real product.
Where does my subscription go?
+
Roughly in this order: electricity to run the dedicated RTX 5090 fleet 24/7, Cloudflare bandwidth, object storage for your creations, Supabase for auth and database, Stripe fees, and then — what's left — subsidizing the free tier for creators who can't pay. ZSky has no venture investors demanding margin. There's no growth team I need to fund. Every dollar goes back into compute, storage, and the mission.
Frequently asked questions
How much does a generation cost?
+
Generation is unlimited on all tiers. No counters, no caps. Free tier runs on the shared queue; paid tiers unlock instant generation on the dedicated RTX 5090 fleet, wordmark plate removed, and — on Ultra and above — 4K with explicit commercial licensing.
Can I cancel anytime?
+
Yes — absolutely. You can cancel your subscription from your account settings at any time with one click. You will keep your paid tier access until the end of your current billing period, then you will automatically revert to the Free plan. No cancellation fees.
Is commercial use included?
+
Commercial use is included on all plans, including the free tier. You can use generated videos and images in client work, products, social media ads, and more. Ultra and above receive an explicit commercial license; Max and Z Creator include white-label rights, ideal for agencies and high-volume commercial projects.
What payment methods do you accept?
+
We accept all major credit and debit cards (Visa, Mastercard, American Express, Discover), as well as Apple Pay, Google Pay, and Link via Stripe. All payments are processed securely by Stripe — ZSky AI never stores or has access to your full card number.
Is there a free trial for paid plans?
+
The Free tier is your trial — unlimited video and image generation, forever, with no credit card required and no ads. This lets you use the platform as long as you like before deciding to upgrade. We do not offer time-limited trials on paid tiers because we do not want to pressure you into a decision.
Can I switch between monthly and annual billing?
+
Yes. You can switch from monthly to annual billing at any time from your account settings. If you switch mid-cycle the change takes effect at your next renewal date. Annual billing saves 20% compared to paying month-by-month.
How does ZSky compare to other AI image generators?
+
ZSky AI consistently ranks among the top free AI tools for video and image generation. See how ZSky compares to every major AI tool in our detailed 12-platform comparison covering quality, speed, pricing, and features.
Your subscription in actual kilowatt-hours
Full transparency. Here's approximately what a Pro subscription pays for each month on our dedicated RTX 5090 fleet. Numbers are estimates based on average load and US commercial power rates.
~30 kWh
RTX 5090 electricity
~5 GB
Object storage
~240 min
GPU compute time
The fleet pulls enough electricity to heat a small apartment for a weekend. Your subscription covers your own compute plus a slice of the free tier that doesn't pay. The math isn't exact — prices fluctuate, usage varies — but the order of magnitude is honest. Every dollar goes back into the cluster, not into marketing or margin.
