Lummi

Lummi is a stock image library built around AI-generated visuals: photographs, illustration-style artwork, and 3D models contributed by a community of creators and sorted into browsable categories. Its homepage promise is “no more boring design”, and the catalogue leans toward the clean, softly lit, editorial look that shows up in SaaS landing pages, pitch decks, and brand blogs. Assets download under a royalty-free licence that permits personal and commercial use without attribution, which is the main reason designers try Lummi instead of a traditional stock subscription.

What separates Lummi from a plain download site is that the editing tools live on the asset page. Reframe moves an image's focal point and zooms in or out, so one picture can be cropped for a square social post and a wide hero banner without losing the subject. Restyle re-renders a chosen image in a different visual style. Background removal produces a transparent cutout. A create-similar action generates variations of an image you like, while paid plans add ultra-resolution downloads and bulk selection from the grid.

The library also covers motion. Paid users can generate clips of up to eight seconds from a prompt, animate a still image, and add audio, which suits short social loops and animated banners rather than production footage. 3D assets open in an interactive viewer where you can rotate the model, pick a camera angle, change the backdrop colour, and export a .gltf file for design tools, games, or interactive prototypes.

Access runs on subscriptions. The free tier allows browsing and standard-resolution downloads, while Pro removes watermarks across the library, unlocks ultra resolution, and adds AI credits on a seven-day trial. Max raises the fast-generation allowance and makes video generation unlimited. Credits stay simple: one credit equals one fast generation, and the fast allowance refreshes hourly instead of accumulating into a large bank.

For teams that want the catalogue inside their own product, Lummi publishes a REST API at api.lummi.ai with bearer-token authentication and endpoints for searching and retrieving images, including metadata such as attribution URL, colour palette, orientation, and focal coordinates. Udemy acquired Lummi in 2025, and the site now carries Udemy's privacy and cookie policies next to its own licence terms.
