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.
ThumbGen
ThumbGen creates YouTube thumbnails from a written prompt, with the option to add reference images. It is a web service, and its output is prepared for YouTube’s 16:9 aspect ratio. FAST produces 1K images, while PRO offers 2K and 4K resolutions. Users can upload as many as eight reference images; each uses one credit. The service also supports creating several variations in one batch. ThumbGen says most images take 10–30 seconds to generate, depending on complexity and resolution. FAST 1K costs 8 credits per image; PRO costs 30 credits at 2K or 55 at 4K. The free plan is free, billed $0 one-time, and includes 150 credits. Starter costs $9.99 a month and includes 1,000 credits monthly; Creator costs $24.99 a month and includes 2,700. Credits reset each billing cycle and unused credits do not roll over. Subscriptions can be canceled anytime, with access through the billing period; subscription payments and unused credits are nonrefundable unless the law requires otherwise. Google sign-in is available, and support and privacy requests go through a contact form.
