FAQ

Can I adapt the system to my own brand?

Yes. Thumbnail Lab reads your colours, fonts and tone from the prompt or a brand file, and keeps them consistent across everything it makes.

Can I provide a visual reference?

Yes. Attach a screenshot or link and mention what you like about it. The Skill uses it as direction, not something to copy.

Does generation cost extra?

The Skill itself is free to run. If it calls a third-party generator, the page lists it under “Generates with” and that provider’s usage applies.
