ThumbnailCreator.ai

ThumbnailCreator.ai sends one prompt to as many as four image models at once, letting users compare thumbnail outputs side by side. The site lists nine models, including GPT Image 2, Nano Banana Pro, FLUX.2 Max, Ideogram 4, and Grok Imagine. Output formats include 16:9, 1:1, 9:16, and 4:5; 16:9 images are 1920×1080 JPEGs under 2 MB. For supported models, users can upload up to four reference images, including faces and products. The web studio accepts Google or email-link sign-in. Its MCP server works with Claude, Cursor, ChatGPT, and other MCP clients; users can connect with an agent key or OAuth connector. The service also offers an Agent Skill and x402 pay-per-call. A free starter credit requires no card, and downloads have no watermark. Paid use draws from prepaid credits that do not expire; failed images are free, and spending cannot exceed the purchased balance. The site says generated-image rights are assigned to the user but AI output is not guaranteed to be unique. There is no layer editor; its FAQ recommends Canva for detailed layout work.
