In their own words
CoverHook
CoverHook generates cover images with AI, arranging artwork and typography for the format you select. Its listed formats include YouTube thumbnails and banners, album and book covers, TikTok and Reels covers, and text covers. For a YouTube thumbnail, enter a title, optionally add a reference image, choose a look, and generate three strategy variants. Each thumbnail receives a 0–100 fit score and rule-by-rule checks for qualities such as subject recognition, contrast, and caption legibility. YouTube exports are 16:9 at 2048×1152 in 2K or 1280×720 in 1K. Text covers instead render on a local browser canvas, use no AI call or credits, and can be exported repeatedly. The free plan is free and includes 25 signup credits, all six cover types, unlimited text-cover exports, and cloud-saved generations. Pro is $99 a year; Studio is $199 a year. The API shares the account credit balance, processes jobs asynchronously, and permits up to three generations in flight per account.
