How it works

1

Choose your platform and enter your product

Select Google Ads, Facebook, LinkedIn, or X. Add your product or service name and any optional targeting details.

2

Add audience and benefit details

Include your target audience and key benefit to shape the messaging. Add a target keyword if you need SEO alignment.

3

Pick a tone and generate

Choose from engaging, professional, casual, bold, playful, or formal. Get platform-specific copy in the right format.

Platform-specific formats

Every output matches the exact character limits and field requirements for Google Ads, Facebook, Instagram, LinkedIn, and X. No manual reformatting needed.

Multiple variations per run

Get several headline and description options for each campaign. Test different angles without writing from scratch every time.

Tone control

Set the voice to match your brand, from formal B2B messaging to playful consumer copy. The same product can speak differently on LinkedIn versus Instagram.

Keyword integration

Add a target keyword and the tool weaves it into headlines and body copy naturally. Useful for search ads and maintaining message consistency.

Audience-aware messaging

Specify your target audience and the copy adjusts its angle. The same product will address small business owners differently than enterprise buyers.

USP highlighting

Enter your key benefit or unique selling point and the tool makes it the anchor of every variation. Your differentiator stays front and center.

How to get the most out of the ad copy generator

This tool writes faster when you give it specifics, not abstractions.

Write the product field like a customer would search for it

Use plain language, not internal product names. If you sell 'CloudSync Enterprise 3.0', write 'cloud file sync for teams'. The tool pulls better angles when it understands what the product actually does.

Include the category if the product name is vague. 'Momentum' tells the tool nothing, but 'Momentum project management app' gives it enough to write benefit-driven copy.

Be specific about the audience, not demographic

Instead of 'millennials' or 'age 25 to 40', write 'freelancers who invoice clients monthly' or 'parents shopping for kids' winter gear'. The tool writes to a mindset, not an age bracket.

If you leave audience blank, the copy stays generic. If you are running different campaigns to different segments, generate separate sets with distinct audience inputs.

Use the benefit field to control the message hierarchy

The benefit you enter becomes the primary claim in most headlines. If your product has three strong benefits, run the tool three times with a different benefit each time, then compare which angle performs.

Write the benefit as a customer outcome, not a feature. 'Automates invoice reminders' is weaker than 'get paid faster'. The tool mirrors your framing.

Match tone to the platform and buying stage

LinkedIn and Google Search ads usually perform better with professional or formal tone. Facebook and Instagram skew casual or engaging. X depends on your brand, but bold often cuts through.

If you are retargeting warm traffic, try playful or casual. Cold prospecting on search often needs professional or bold to establish credibility fast. Run both and test.

Frequently asked

Can I use this for Google Shopping ads or display ads? +

This tool is built for text ads: Google Search, Facebook feed, LinkedIn sponsored content, and X promoted posts. Display ads and Shopping ads use different formats and image-text combinations that this tool does not cover.

Do I need to fill in every optional field? +

No. The tool works with just platform and product. Adding audience, benefit, keyword, and tone makes the output more specific and aligned to your campaign, but they are not required.

Why does the tool give me multiple headlines and descriptions? +

Ad platforms let you load multiple headlines and descriptions, then rotate or test them. The tool gives you a set so you can upload several variations at once instead of writing each one separately.

Can I edit the output before using it? +

Yes. Treat the output as a draft. You know your brand voice and offer details better than any tool. The copy is platform-ready in format, but you should adjust wording to match your style and fact-check any claims.

What if the copy does not match my brand voice? +

The tone selector gives six preset voices. If none fit, pick the closest one and edit the output. Inside a Letaido workspace, you can set a custom brand voice that applies across every tool, including this one.

Does the tool check character limits automatically? +

Yes. Every headline, description, and body text field is generated within the platform's character limits. You can copy and paste directly into your ad account without trimming.
