AI without a subscription: why credits should never expire
In short
TL;DR: subscription AI charges you every month whether you create or not, and resets unused credits. Fattly is pay-per-credit — you buy once, credits never expire, and there is no mandatory subscription.

Why subscription AI quietly costs you more
Most AI tools run on the same model: a monthly seat that charges you whether you create ten videos or none, plus a credit allowance that resets at the end of the month. Miss a busy week and the credits you paid for are gone. Take a slow month and you still pay full price. It is built to bill you on a schedule, not on what you make — which is great for the tool and quietly expensive for you.
What pay-per-credit changes
Pay-per-credit flips it: you buy a pack of credits, spend them whenever you want, and nothing resets at midnight on the last day of the month. If you create in bursts — a launch, a campaign, a busy season — your credits are there when you need them, not forfeited because the calendar turned. You pay for output, not for the privilege of having an account open.
How Fattly prices it
Fattly is pay-per-credit across everything — images, video, voiceovers, avatars, try-on and more, all from one credit pool 50+ AI models. Credits never expire, there is no mandatory subscription, and you start with 10 free credits without entering a card. A monthly plan exists if you want top-ups on autopilot, but it is a choice, not a gate: the tools work the same either way, and even subscription credits do not expire.
One pool matters more than it sounds. Because the same credits cover every tool, you are not juggling separate plans for image, video and audio — you decide per project what to spend them on, and unused credits keep their value for the next one.
| What to look for | Typical subscription AI | Fattly |
|---|---|---|
| Billing | Monthly seat, use it or not | Pay per credit, only for output |
| Unused credits | Reset every month | Never expire |
| Subscription | Required | Optional |
| Coverage | Often one tool per plan | One pool across 50+ models |
| Free start | Trial with a card | 10 free credits, no card |
| Slow months | Still pay full price | Pay nothing extra |
Who this suits best
Anyone who creates in bursts rather than every single day: sellers running seasonal campaigns, freelancers with uneven client work, founders who need a wave of content at launch and little in between, and teams who would rather not defend a monthly line item they only half-use. If your workload is not perfectly flat, a plan that bills flat is quietly overcharging you.
Try it before you commit to anything
The point of the model is that you do not have to commit to find out. Start with 10 free credits and no card, generate a few things across images, video or voice, and see how far a credit goes for your work. If you keep going, you buy more — and whatever you do not spend is still there next month.
Frequently asked questions
Do the credits really never expire?
Yes. Credits you buy on Fattly do not reset monthly and do not expire, including credits that come with a subscription. Whatever you do not use this month is still there next month, so you never lose paid-for credits just because the calendar turned.
Is there any mandatory subscription?
No. Fattly is pay-per-credit by default. A monthly plan exists if you want credits topped up automatically, but it is optional — the tools work the same whether you subscribe or just buy credit packs when you need them.
Does one credit pool cover every tool?
Yes. The same credits work across images, video, voiceovers, avatars, try-on and the rest — 50+ AI models under one roof. You decide per project where to spend them instead of buying a separate plan for each type of content.
How do I start for free?
You get 10 free credits without entering a card, which is enough to generate a few things and see how the credits stretch for your work. There is no trial countdown and no subscription to cancel — you only pay if you choose to buy more.
