Image and video decision
ThumblifyAI
A usable thumbnail-generation service is realistic for a single capable developer to implement using existing image-generation APIs and standard web stacks; no durable moats are evident from the provided page.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- User uploads or links media + title/brief → generate thumbnail image via image-generation API or model + apply text/layout templates → return downloadable thumbnail and metadata
What it still won’t have
- Proprietary trained image models and any private production optimizations
- Hosted SLAs, analytics/dashboard polish, and built-in integrations specific to vendor
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal AI-powered thumbnail generator using Next.js for the frontend, Node.js/Express for the API, PostgreSQL (or SQLite) for metadata, and AWS S3 (or local storage) for images. Core features in scope: 1) upload/accept image or video link and a title/brief; 2) generate 3 thumbnail variations by calling an external image-generation API (configurable API key); 3) apply templated overlays (title text, logo, platform crop presets) and produce final 1280x720 JPG/PNG outputs; 4) store thumbnails and metadata and provide preview/download links; 5) simple web UI to select and download a thumbnail. Out of scope: training custom models, multi-user billing, analytics dashboard, and complex design editor. Include input validation, retry/backoff for API calls, basic logging, automated unit tests for API routes, and end-to-end test for the generation flow.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
