Thumbnail StudioIn development

AI imagery. Editable everything else.

Most AI thumbnail generators hand you a flattened image — fix one word and you regenerate everything. Thumbnail Studio splits the work: AI creates subjects and backgrounds, while typography, layout, shadows and logos live as editable layers on a standard 1280×720 canvas.

Concepts before pixels

Image generation is the expensive part, so it comes last. First you get cheap written concepts — layout, subject, text, emotion, composition — and choose which ones are worth rendering. No burning credits on directions you'd never use.

A real editor underneath

The canvas supports the things an actual thumbnail workflow needs:

  • Layers: images, cutouts, text, shapes, logos, screenshots, gradients
  • Effects: shadow, stroke, glow, background blur, vignette
  • Version history — every major state kept, compare and restore any of them
  • Preview at real YouTube sizes: desktop card, mobile card, tiny suggested-video size
  • A brand kit for your faces (tagged by expression), logos, fonts and colors

An analyzer that tells the truth

No “Predicted CTR: 13.2%”. The analyzer flags concrete, checkable issues — “the screenshot becomes unreadable at small sizes”, “the thumbnail text repeats the title” — and each finding comes with a one-click fix that saves as a new version instead of destroying your work.
