Use ThumbnailMaker inside ChatGPT or Claude
Connect once, then ask your AI for a thumbnail. It tells you the price, you say yes, and the thumbnail comes back in the chat, with the words drawn in and checked at feed size.

Good to know
- It always tells you the price first and waits for your yes before it spends anything.
- It costs what the app costs: one thumbnail is 10 credits, 4K or a second take counts double, three to test is 30. Nothing extra for using it from a chat.
- If an image fails, its credits come back on their own.
- Every thumbnail also lands in your Library, ready to download.
- Making thumbnails from a chat is part of the Studio plan ($99 a month, 300 thumbnails). The brief and the check work on any account, free.
