Commercial use is the first line to read
Commercial use is the permission to put a generated image, clip or voice track into something you get paid for. It decides whether a tool suits paid work, so it is the first line to read and the easiest one to check.
Several brands in this group state it plainly: Canva Pro, Cartesia, Coinis, ElevenLabs, Leonardo.Ai, Luma AI, Midjourney and Recraft. The Canva Pro review shows how that permission is written out in full, and the Cartesia review covers a voice tool where the finished output is an audio file rather than a picture.
Where a brand does not put commercial use in a single clear place, read its terms yourself and keep a copy of the wording you relied on. A tool built for personal projects is not automatically a tool for client work, and a voice tool raises a different question from an image tool, so treat each brand on its own terms.
Check the output ceiling before you plan the layout
A resolution figure tells you the largest file a plan exports. That number decides whether you can fill a wide layout, meet a platform's dimension rules, or keep a usable copy after compression.
The figures in this group differ sharply. HeyGen lists an output of 4K and Podcastle lists 4K. DeepSwap lists 4K for photo work, Descript lists 1080p and Luma AI lists 1080p, and Pornpen.ai lists 2048 x 2048 px for square still images.
Read each figure next to the kind of work it applies to. A square still and a wide moving clip are not measured on the same scale, so compare a tool against another tool doing the same job rather than against the largest number in the list.
Some brands publish a ceiling and some leave you to find the export settings yourself. Either way, download one finished file early and open it on the screen where you will actually use it, before a month of credits has gone.
Credits are not the same unit everywhere
A credit number on its own tells you very little. The unit behind it is what decides how far a plan goes, and lists with similar-looking numbers can sit a long way apart in practice.
Some bill against the finished item. DeepSwap charges 0.1 credit per photo and Promptchan uses Gem credits per generation. Others meter a broader resource: Midjourney meters GPU time, not per-image credits, Leonardo.Ai meters About 1 token per image, and Recraft sets Credit-based; cost varies by action and model.
One brand states its allowance against a named plan. Keywords.am gives 30 per month on Seller plan, so the same figure may not carry over to another tier. Coinis works differently, with Credit-based; recipe varies by generation type, and Podcastle simply describes credit-based.
The habit worth building is small: write the unit next to the price every time you compare, and only then compare the numbers. A plan metered in processing time behaves very differently from one metered per photo, even when the headline price looks similar.
Still images or motion
Video generation is listed for most brands here, from AI/ML API and Chutes through to Pictory and Promptchan, with Canva Pro, Careerflow, Coinis, DeepSwap, Descript, ElevenLabs, Guaramo, HeyGen, Leonardo.Ai, Luma AI, Minimax, Picsart, Podcastle and Pornpen.ai in between. Motion is not the scarce part; the deciding questions are whether the credit unit covers what you want to make and what the output ceiling allows.
Start with the NSFW AI video generators ranking when motion is the goal, then widen to the NSFW AI image and video generators list when you want a single tool for both a thumbnail and a clip.
The Careerflow review and the Coinis review are useful next stops, because a business-facing tool and a credit-metered tool reach motion on their own terms.
Free access, plan names and keeping records
Free access, where a brand offers it, appears as its own entry in the plan list rather than as a hidden allowance, so look for that entry before you sign up. Where a figure is tied to a named plan, such as the Seller plan inside 30 per month on Seller plan, treat it as belonging to that plan alone.
Billing terms deserve the same attention as the price. Note the plan name you pick, the renewal date and how to cancel, then check those details again before the renewal rather than after. A brand that answers such questions in plain language is easier to plan around than one that leaves them out.
Keep your own paper trail. Save each prompt, the finished file and the plan it came from in a single folder, and keep the receipts beside them. It takes minutes, it costs nothing, and it settles the first question a platform or a client is likely to ask about an image or a clip.
A routine you can repeat for any brand
The order matters. Read commercial use first, because it can end the comparison on its own. Then read the output ceiling, then the credit unit, then the video question, then the free entry and the billing terms.
Give every brand the same short note: the permission you rely on, the largest file it exports, what a credit buys, and what you would be billed for. Brands that answer all of that in plain terms are worth a longer trial, and brands that answer none of it are worth leaving.
That is the whole method. It costs nothing, it fits into an afternoon, and it keeps an awkward surprise from reaching your inbox later. When two brands look alike at first glance, the credit unit is usually the line that separates them.
