About this tool
The generator asks Claude, an AI model, for ten headlines and four descriptions for a responsive search ad. Headlines vary between the keyword, a benefit, a proof-free offer and a call to action. Descriptions expand on the offer and end with a clear next step.
Describe your product or service, add the keyword you bid on, state your real selling point such as free delivery or a 2 year warranty only if it is true, and run it. A length table checks every line against Google's limits so you can trim any that run long before you paste them into your account.
The description box takes up to 800 characters. The AI cannot count characters exactly, so trust the table. Ad copy is AI-generated and not policy-checked, so make sure every claim is true and fits Google Ads policies on restricted content, superlatives and trademarks. Test several headlines against each other rather than trusting one.
Frequently asked questions
What are the Google Ads character limits?
Responsive search ad headlines can be up to 30 characters and descriptions up to 90 characters. The tool aims for those limits and lists each line in a table with its length, marking any that run over.
Will the ads pass Google Ads policy?
Not automatically. The AI does not check policy. Avoid unproven claims, excessive capitalisation, misleading offers and trademarks you do not own. Google reviews every ad, so read its current advertising policies for your industry before you launch.
How much text can I use, and are there limits?
Each run accepts up to 800 characters for the offer description. There is also a fair-use limit on AI runs per visitor each day so the tool stays free. When you reach it, the free tools that do not use AI still work, and you can run this one again the next day.
How accurate is the AI output?
No AI output is guaranteed accurate. This tool can misread your meaning, repeat a common phrase or state a detail you did not give it, so read the ad copy through, check every name, number and claim, and edit it before you publish. Treat it as a fast first draft that you review, not finished copy.
