Which of the four are you being sold?
The widest word in the category covers four things that share a prompt box and nothing else, including their price per usable result.
The question
Before any vendor comparison is worth running, one decision has to be made correctly, and it is the one most buyers skip: which kind of generator the work actually needs. Get it wrong and the best product in the category is the wrong purchase.
The four shapes, by what their pricing page bills
| Billed by | What is being sold | Relative unit cost | Check |
|---|---|---|---|
| Messages or a monthly seat | Conversation | Lowest | Companion chat |
| Images or credits per image | Stills | Low | Image generators |
| Seconds of animation from an upload | Motion on your own frame | High | Image to video |
| Seconds generated from text | Clips from a description | Highest | Video generators |
What we checked
- Pricing pageAre the limits stated in units a buyer can count?
- Satisfied by
- Clip length in seconds, resolution in pixels, generations per day as a number, queue priority described in words that mean something.
- Usually found
- A credit balance with no stated conversion, and the word unlimited somewhere above a fair-use clause that contradicts it.
- At stake
- This is the difference between a subscription that finishes work and one that runs out on a Tuesday.
- Checkout and cancellationWhat appears on the statement, and how does a subscription end?
- Satisfied by
- The billing descriptor published before payment, renewal terms stated in the flow, and cancellation available from inside the account.
- Usually found
- An undisclosed descriptor, a trial that upgrades to annual, and cancellation by email to an address answered in business days.
- At stake
- Subscription disputes are the most common complaint in adult services, and every one of them was decided at checkout.
- Terms of serviceWho holds rights in what the tool produces?
- Satisfied by
- An explicit grant of output rights to the user, and a narrow, stated licence back to the vendor for operating the service.
- Usually found
- Silence about the user's rights and a broad perpetual licence to the vendor covering promotion and model training.
- At stake
- Publishing anything made with the tool depends entirely on this paragraph, and it is never on the pricing page.
- Support channelCan a question be asked before any money moves?
- Satisfied by
- A channel that answers a pre-sales question — anything from a ticket form to a staffed chat — with a human reply.
- Usually found
- A form that routes to nothing, or a help centre whose articles were written for a different product.
- At stake
- The channel that will not answer before payment is the channel that will not answer about a renewal.
Verdict
Decide the shape first, the vendor second
Work that needs a recurring character belongs in stills plus animation, not in prompt-to-video, whatever the second one's samples look like. Settle that on the billing unit before comparing brands, and the vendor question becomes small — which is the opposite of how this category is marketed.

Questions
- Why does the shape of the product matter more than the brand?
- Because the four shapes have unit costs an order of magnitude apart. Someone who buys prompt-to-video when their work needed stills plus animation will spend roughly ten times as much to reach the same result, and no amount of vendor quality fixes that.
- How do you tell which shape a product is?
- By what its pricing page charges for. A service billing per generated second is selling video. One billing per image with an animation add-on is selling stills first. One selling a monthly companion with image credits attached is selling chat. The marketing describes all three as an AI generator.
- Is free ever a real tier here?
- Three different things wear the word: a trial balance, an ongoing capped tier, and ad-supported access with a queue. Only the second survives past the first week, and vendors use the same word for all three deliberately.
