AI Ad Copy Generator
Describe your product and audience, pick a platform, and get five ready-to-run ad variants — written to the right character limits — plus three tips to improve them.
Writing ads that actually convert
Strong ad copy leads with a specific benefit, not a feature. Name the customer's problem, promise a concrete outcome, and finish with a clear call to action. On Google, every character counts — front-load your keyword and value in the first headline. On Meta, the first line of primary text has to stop the scroll. On LinkedIn, credibility and specificity beat hype.
Generate a batch, keep the two or three that fit your brand voice, and A/B test them. Small changes to the headline usually move click-through rate more than anything else.

Frequently asked questions
How long can Google ad headlines be?

Does this work for Meta and LinkedIn ads too?

Is the ad copy generator free?
Yes, it is free and needs no login. There is a fair-use hourly limit to keep it available to everyone.
