There is no free tier here — there is a one-off trial, and it is small. You get a small one-off batch of credits (the platform's unit of spend — each thing you make costs some) when you create an account, no card asked for — by Ludo's own documentation, enough for a few dozen images, or a handful of short sprite animations or 3D models. Ludo's docs call it a free trial; its FAQ calls it the free plan; the pricing comparison table has no free column at all, and none of the three says the trial credits come back. Assume they don't. Start at ludo.ai and spend a few credits on ideas and images before anything expensive.
Producing an actual set of characters means paying. The entry plan (Indie) comes with a monthly credit allowance — granted as a full year's worth up front on the annual plan, which is cheaper per month, with unused credits rolling over while the subscription is active. The next tier up (Pro) costs more; current prices are on its Launchpad page.
Anything you download on the free account is stamped. Ludo's FAQ and its sprite documentation both say sprite sheet downloads on the free plan carry a Ludo watermark on every single frame, and that subscribing to any paid plan removes it — the FAQ says without needing to generate the art again. So the trial is for deciding, not for producing.
You have to be an adult. The Terms of Service and End User Licence Agreement in force today (Jet Play, Inc., dated 26 August 2026) states plainly: "You must be at least 18 years of age to use the Service."
It works in English. Ludo says its interface and the content it generates are in English, with parts of the website and several tool guides also available in German, Spanish, Korean, Portuguese and Chinese. No vendor page states a regional restriction — though not saying so is not the same as confirming it is available everywhere.
