🖱️ ThumbWorks

Thumbnails + titles engineered for the click — from your video's promise to a packaging pair worth posting.

Canva Pro charges $120–$144/yr — and Canva isn't click-tested. ThumbWorks is $99 once, with a CTR scorecard on every pair.

Your packaging boards

Home = one board per video: setup, titles, thumbnail concepts, CTR scorecard, and your A/B pick. Saved on this device. No account, no gate.

1 · Video setup

The promise drives everything below. Change it, then re-generate titles and concepts.

Working title Topic — what the video is actually about, in a few words The promise — what the viewer gets if they click Audience Target emotion 3 key visuals — one per line: the strongest things that could appear in the thumbnail

2 · Title generator

Six proven angles. Each title is scored on length, curiosity cues, and power words — the score shows its work, it isn't magic.

Add your own title

3 · Thumbnail concepts

Four layout types, each with big text (3 words max), a contrast-checked palette, and face/object direction. Tweak the text, emoji, and colors — the mock updates live.

Honest note: these mocks are layout previews — they show composition, text size, and contrast so you can brief a designer, recreate the layout in Canva/your design tool, or use the layout as your base. ThumbWorks does not generate fake photos of you or anyone else.

Small-size preview — the squint testShrinks every mock to phone-feed size (~168px). If you can't read it there, it won't earn the click.

4 · CTR scorecard

Pick a concept + a title to make a pair. The scorecard checks readability at small size, real contrast ratio, curiosity, and emotion — with the reasons listed.

5 · A/B pick board

Set two pairs head-to-head, note why, and mark the winner you'd actually post. Scores are guidance — your notes are the decision.
