Credits
A prepaid unit that a tool deducts each time you generate something, such as an image, a minute of video or an AI reply. Plans usually include a fixed number per month, and different actions can cost different amounts.
What to check: Check how many credits one finished piece uses and whether unused credits roll over or expire at the end of the month.

Per-seat pricing
The listed price is for one user, and the bill is that price multiplied by the number of people on the account.
What to check: Multiply by your team size, and check whether viewers or guests also count as paid seats.

Billed annually
A monthly price that only applies if you pay for 12 months up front. The month-to-month price for the same plan is usually higher.
What to check: Compare the yearly total with 12 times the monthly price, and check the refund rules before committing for a year.

Free plan
A plan that costs $0 with no end date, usually with limits on usage, features or output quality.
What to check: Look for the monthly usage cap and whether free output carries a watermark or excludes commercial use.
Seen in the pricing of 5 tools here, for example:
Free trial
Temporary access to a paid plan for a set number of days, after which you must pay or lose access. Some trials need a card up front.
What to check: Note the end date and whether the trial converts to a paid plan automatically.

Usage-based pricing (pay as you go)
You pay for what you use, for example per minute, per call or per request, instead of a flat monthly fee.
What to check: Estimate your real monthly volume and multiply it by the unit price before comparing with flat plans.

Tokens
The unit AI language models use to measure text. API prices are usually quoted per million input or output tokens.
What to check: Output tokens usually cost more than input tokens, so check both prices.
Seen in the pricing of 1 tools here, for example:
API pricing
Separate pricing for developers who call the tool from their own software. It is often billed by usage and is not included in the consumer subscription.
What to check: Check whether the subscription you pay for includes any API access, or whether it is billed separately.
Seen in the pricing of 7 tools here, for example:
Watermark
A logo or label the tool adds to images or videos, usually on free or entry plans, and removed on paid plans.
What to check: If you publish the output for a business, check which plan removes the watermark.

Permission to use what the tool generates for business purposes such as ads, client work or products for sale. Some free plans exclude it.

Enterprise / custom pricing
A top plan with no public price: you contact sales and get a quote based on team size, usage and support needs.
What to check: Small teams can usually ignore it unless they need single sign-on, admin controls or a contract.

Add-ons and overages
Extra charges on top of a plan, such as more credits, minutes or features bought separately, or fees when you go past the plan's limit.
What to check: Check what happens when you hit the limit: service stops, you are upgraded, or you are charged per extra unit.
