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, with one clear idea and no clutter, so it is easy to grasp in a feed. It ties a well-known brand to the AI writing topic people are already searching for. The data also shows it has run for 179 days and is still active on 11 ads, which suggests the message keeps performing, though that is a signal and not proof of why.

Who it speaks to: Working professionals who write every day, such as emails, documents and reports, and want to get it done faster with less effort.

How it’s built

Hook: The headline 'Your AI writing assistant' names the product and its category straight away.
Benefit: The post text promises working faster and smarter with support at every step.
Credibility: The description says professionals rely on it, which signals trust without giving a number.
CTA: The Download button and grammarly.com caption point to a low-friction next step.

What to borrow

Lead with a headline that names what you are and the key benefit in a few words, so the right person recognises it at once.
Keep one core promise per ad and support it with a short line on speed or ease.
Use a soft credibility line like 'professionals rely on it' only if you can back it up truthfully.
Match the button to the action you want, such as Download for an app, so the next step is obvious.
