What you can do for free, and what needs a plan.
Free for anyone signed in: watermarks
The Watermark tool puts your logo on your photos - one picture or as many as you add, as a single mark or a tiled or diagonal pattern - and uses no credits. Anyone signed in can use it, with or without a plan.
How Cutlin is paid for
Cutlin's AI needs a sign-in and a paid plan: Starter, Pro, Business or Enterprise, billed monthly or yearly. Plans differ only in how many credits they give each month - an image uses 5 with the Fast model, for example - and every feature is on every plan.
If you run low, credit packs of 500, 2,000 or 5,000 credits top up your balance, and they do not expire. Prices are on the pricing page.
The brand you use
A brand used in Cutlin is a Melon Cut Guidelines brand. Its Free plan keeps private guidelines, and Cutlin can use them to keep its results on-brand; its paid plans, priced per brand, add public guidelines at the brand's own address. Those prices are on meloncut.com.
