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

Running 217 daysFacebookWinner

How it opens

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

Angle: Feature

Why it works

It is clear and low friction: one headline says what the product is, one line says the benefit, and the button asks for an easy action. It leans on the AI trend and an already familiar brand, so it does not need to explain much. The data shows it has run for 217 days and is still active across 12 ads, which suggests this simple, consistent message keeps performing for the advertiser.

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 giving numbers.
CTA: The Download button and grammarly.com caption point to a simple next step.

What to borrow

Open with a headline that names what your product is in plain words, especially if it ties into a topic people already care about.
Pair one clear benefit line with a single action button so the ad has one job.
Use a light trust cue such as 'professionals rely on it' when you have no hard numbers, and add real proof if you do have it.
Run a consistent core message across several ad variants and let the long-running ones show you what to keep.
