Pictley

Pictley makes YouTube thumbnails from a written prompt, a rough sketch or an existing thumbnail you want to restyle. It is aimed at video creators who would rather not spend hours in a design app for each upload.

There are three modes. Thumbnail generation works from a text description, sketch to thumbnail turns a quick drawing of the layout into a finished image, and thumbnail recreation applies a new style or theme to an existing design.

Example prompts on the site show split-screen comparisons, bold title text, cinematic lighting and cartoon styles, which reflects the click-focused look most YouTube channels use. A light and dark theme toggle and account sign-in are available.
