What is included in each ad set?

Each ad set contains 3 headlines (30 chars each: Google standard), a description (90 chars), body copy (125 chars for social), and a CTA button text (15 chars). Character counters are colour-coded to show if you're within limits.

How does the platform selection affect the output?

Google copy is clear and direct with strong action verbs. Facebook and Instagram copy is emotional and visual, designed to stop the scroll. LinkedIn copy is ROI-focused and professional. Twitter/X copy is punchy with hashtags.

What are Google Ads character limits?

Google Responsive Search Ads allow up to 30 characters per headline and 90 characters per description. The tool's character counters turn green when within the limit, yellow when close, and red when over.

Can I copy an entire ad set at once?

Yes. Each set has a 'Copy Full Ad Set' button that copies all fields: headlines, description, body copy, and CTA: as structured plain text.

Does the tool use an AI API?

No. All copy is generated using template-based formulas in your browser. The tone, platform, goal, and your inputs are combined using string interpolation: no server request is made.
