An AI thumbnail concept generator that does more than generate.
Generate the concepts, then explore, compare, and pick the winner. All on one AI-native infinite canvas.
AI that reads the whole canvas as context
AI that knows your channel
One prompt to a set of concepts: Describe the video and AI generates a board of thumbnail concepts with layout and text.
Canvas-aware AI: AI sees your past thumbnails and channel notes, so concepts stay on-brand.
200+ frameworks built in: Retention hooks, visual hierarchy, and more. Pick one or let AI suggest the right fit.
Re-prompt until a concept stops the scroll
Re-generate and explore angles
Keep prompting: Ask the AI for bolder text, a different focal point, or fresh angles. It keeps the context.
Branch out ideas: Map variations of a strong concept and explore where each one could go.
Start from a template: Use a starter framework for YouTube, shorts, or course thumbnails, or build your own.
Sketches, references, and notes on every concept
Build a thumbnail with references
Drag in anything: Drop in screenshots, photos, links, and sketches to flesh out a concept.
Sketch the layout: Rough out the composition with the pen tool right on the canvas.
Notes and direction: Write the visual direction next to each concept so the designer knows the intent.
Cursors, comments, and live edits across the board

Reilin Joey

“One prompt gets me a structured board. But the tactics are my favorite. I run my YouTube scripts through them and my intros and retention got better. It's amazing.”
Justkay
YouTuber & Freelance Filmmaker
“I used to juggle five apps to plan a project. Now I describe what I am making and get boards, lists, and a schedule. All in one place.”
