Thumix
What it is
Thumix is a browser-based AI thumbnail maker that creates images in styles drawn from YouTube videos and other reference images, using a creator’s face and topic. Users can start from templates, generate images from scratch, or create and edit them in Canvas. Templates cover niches including gaming, vlogs, education, business, health, and beauty. The site lists Nano Banana models and GPT 2.5 Flare and Sunburst; image generation uses 2 to 4 credits depending on model and quality. Signing in with Google provides 2 free credits, which Thumix says are enough for one thumbnail. The Try plan is $1.99 a month for 20 credits, Pro is $7.99 a month for 100 credits, and Studio is $15.99 a month for 250 credits. Each includes all AI tools and models, commercial use, and credits that never expire. Thumix also offers custom workflows for teams, including batch generation and delivery into a CMS, CDN, or storefront. The maker says generated images may be used commercially if users have rights to uploaded references.
