Grammarly’s image ad: “Your AI writing assistant”

Running 179 daysFacebookWinner

How it opens

“Work faster and smarter with an AI assistant that supports you at every step.”

Angle: Feature

Why it works

The message is simple and uses very little copy, so it is easy to read quickly in a feed. The data also shows it has run for 179 days, is still active, and sits in a set of 10 active ads with a win score of 94, which suggests this plain, clear positioning holds up over time. The Download button matches the app category and lowers friction for someone ready to try it.

Who it speaks to: Working professionals who write every day, such as emails, documents and reports, and want to save time and avoid mistakes.

How it’s built

Hook: The headline states plainly what the product is, an AI writing assistant, and frames it as 'yours'.
Benefit: The post text promises faster, smarter work with support at every step.
Credibility: The description says professionals rely on it, which hints at trust without citing a number.
CTA: The Download button and grammarly.com caption point to one clear next step.

What to borrow

Name what your product is in the headline so the right person recognises it in a second.
Pair one broad benefit, such as speed, with a reassurance line so the promise feels dependable.
Keep the copy short and let a single button carry the action, especially for a product people already understand.
Run a small family of similar ads and let long-running ones show you which plain message earns its place.
