How it works

One workflow. Three unfair advantages.

Replace creative guesswork with a repeatable system designed for YouTube launches, weekly publishing, and constant iteration.

01

Upload your video

Drop in your latest upload, audience niche, and publishing goals. An Co reads the context before it creates a single concept.

02

AI generates variations

Get thumbnail concepts with bold visual hooks and title options tuned for curiosity, clarity, and retention.

03

We A/B test the winner

An Co rotates combinations, measures click-through rate, and promotes the best-performing pairing automatically.

Features

Everything tied to the click.

An Co keeps the stack simple: generate, test, measure, and keep only the concepts that outperform your baseline.

AI thumbnail generation

Generate fresh thumbnail directions built for your niche instead of recycling the same stale visual formula.

AI title suggestions

Create headline variations that balance intrigue with clarity so more viewers choose your video immediately.

A/B testing

Test multiple title and thumbnail pairings on live traffic instead of betting your launch on a guess.

CTR analytics

See which combinations lift click-through rate, where momentum starts, and which concepts deserve a second pass.
