twirl is a web service at twirl.tools that generates PBR materials (albedo, normal, roughness, metallic, and height maps) from a text prompt. By using twirl, you agree to these terms.
Account
You sign in with email. You need a verified email to generate. Don't share your account. You are responsible for activity on it.
Credits and plans
Free accounts get 5 generations per day at 1× resolution. Free generations are public.
Paid plans and credit packs are billed through Lemon Squeezy. Standard is $16/month (80 credits). Pro is $25/month (160 credits). Credit packs are one-time. One credit generates at 1×, two credits at 2×, four at 4×. Paid plan credits roll over for one month.
Credits are not cash. Unused credits have no cash value. We don't refund credits except where the law requires it. Cancel a subscription in the Lemon Squeezy customer portal. Canceling stops the next renewal. You keep unused credits until they expire under the rollover rule.
Materials
You can use materials you generate on twirl commercially, on every plan.
Public materials show in the feed and anyone can download them. Free generations must be public. Private materials need a paid plan or credits.
You own the materials you generate, subject to these terms. You also grant twirl a license to host them, show them on the site, and, for public materials, let others download and use them.
Don't generate content you don't have the right to request. Don't use twirl for anything illegal, to infringe someone else's rights, or to abuse the service.
We may remove materials or suspend accounts that break these terms.
The service
Generation uses Patina AI. Results vary. We don't guarantee a particular look, uptime, or that the service will stay available in its current form.
twirl is provided as is. To the extent the law allows, we are not liable for lost profits, lost data, or indirect damages, and our total liability is limited to what you paid us in the 12 months before the claim.
We can change these terms. The updated terms apply once posted. If you keep using twirl after that, you accept them.
