what AI can build
Generate YouTube thumbnail concepts and images using AI models with custom prompts and creator-focused workflows.
A basic AI thumbnail generator can be built quickly using existing image models, but recreating ThumblifyAI requires much more than connecting an image API. The product's advantage comes from specialized thumbnail-focused system prompts, AI workflows, creator-focused features, thumbnail inspiration, style matching, AI customization features, and continuous iteration around generating clickable YouTube thumbnails.

the prompt
Catalog estimateBuild me a personal YouTube thumbnail generator inspired by ThumblifyAI. Requirements: - Node + Express, one localhost page; no accounts, no telemetry, keys in .env. - Input: video title, a face/subject photo upload, and a style picker with 5 presets (bold MrBeast-style, minimal tech, tutorial, vlog, gaming). - Generation: send the title + style prompt to an image model API (key in .env; support OpenAI Images or Replicate, one flag to choose). Composite the uploaded face onto the generated background with sharp: auto-cutout via an rembg CLI call, drop shadow, rim light. - Text layer: the title (or a punchier 3-5 word hook the LLM suggests) rendered with sharp over the composite, thick outline, 2 font choices. - Output 1280x720 PNG under 2MB, plus a 3-variant grid so I can pick; save every result to thumbnails/ with the prompt used, so styles are repeatable. - A history page of past generations with one-click re-run. - Out of scope: accounts, teams, A/B testing against YouTube analytics, and bulk generation. This is one thumbnail at a time for my own channel. - README: which API keys I need, rembg install, and rough per-image cost.

Can AI replace ThumblifyAI?
