AI ad copywriter for Meta, Google Search, TikTok and LinkedIn
Ad Copywriter reads your product and landing page and writes ad variants from different angles for the platform you pick; it counts every field against the platform's character limit and adds a compliance note. Nothing is uploaded to an ad account – you paste the copy.

What the agent does
The agent first reads your landing page and searches your knowledge base for prices, guarantees, delivery and reviews or numbers it can use as proof. It then picks 2–4 angles (pain point, outcome, social proof, price, how it works) or uses yours; each angle rests on an insight and, where possible, a verifiable proof point. Your brand voice and the audience messaging in your strategy document are added automatically.
Fields follow the platform: Meta primary text (first 125 characters), headline ≤ 40 and description ≤ 30; Google responsive search ads with 3–15 headlines (≤ 30 each) and 2–4 descriptions (≤ 90 each); TikTok ad text ≤ 100 characters; LinkedIn intro text and headline. A variant over a hard limit is rejected in code and rewritten; fields over the recommended length, exclamation marks in Google headlines, shouting in capitals and absolute claims such as “best” or “guaranteed” are flagged.
The compliance note covers unproven superlatives, the rule that an old price must be the lowest of the 10 days before a discount, health and alcohol restrictions, and the “Reklam” (ad) label needed when an influencer uses the copy. You can also check the copy with Compliance Checker before it goes live.
Inputs / Outputs
Inputs
- Ad platformrequired
- Meta (Facebook and Instagram), Google Search (responsive search ad), TikTok or LinkedIn. Fields and character limits depend on the platform.
- Product / offerrequired
- The product or service and the offer: “Monthly coffee subscription – first box 20% off”. The agent only uses prices stated here, on the landing page or in the knowledge base.
- Audience
- Who sees the ad, in one sentence. Left empty, your project's target audience is used.
- Angles to test
- One angle per box: pain point, outcome, social proof, price. Left empty, the agent picks 2–4 different angles.
- Number of variants
- How many variants to write, 1–10 (default 3). They are spread across the angles.
- Landing page
- The page the ad links to. The agent reads it, and the ad never promises more than the page does.
Outputs
- variants
- The ad variants: angle, platform fields (Meta primary text, headline, description; Google headlines, descriptions and path; TikTok ad text; LinkedIn intro text and headline), CTA button and flags to review. In a workflow each variant is its own item.
- angles
- The angles tested: short name, the audience insight and the proof it rests on (landing page, knowledge base or input).
- complianceNote
- A short compliance note: the rules applied, claims and prices to verify before publishing, and the Reklam label reminder for influencer use.

Integrations it uses
Example tasks
- “Write Meta ads for our coffee subscription: 3 variants, angles cold coffee at the office, fresh roasting and the 20% first-box discount.”
- “Prepare a Google responsive search ad for 'breakfast near me' searches: 15 headlines, 4 descriptions, linking to our booking page.”
- “Write a LinkedIn ad for our B2B web design service; lead with delivery in 3 weeks for small business owners, no exaggerated claims.”
- “Write TikTok ad text for our new skincare line; no medical claims, 4 variants.”
Tips for good results
- Give the landing page link: the agent takes prices, the offer and proof from there instead of inventing them.
- List 2–3 angles and test them on the same budget; expand the winning angle with new variants in the next run.
- Read the flagged fields; keep claims like “best” or “guaranteed” only if you can document them.
- If an influencer posts the copy, put the “Reklam” label in the first line and switch on the platform's paid-partnership label.
Model advice
Default model
Claude Sonnet 5
Per 1M tokens: $2 input · $10 output
Economy model
Claude Haiku 4.5
Per 1M tokens: $1 input · $5 output
The default balanced model is a good balance for short but persuasive fields that must respect the limits. For a few variants or shortening an existing ad, the economy model is usually enough. Stay on the balanced model when you ask for many Google variants with 15 headlines each.
Frequently asked questions
Does it upload the ads to my account?
No. The agent writes copy only; there is no ads integration. You copy the variants from the report or the workflow into your ads manager.
Does it really respect the character limits?
Yes. Hard limits are counted in code, Turkish letters count once. A variant over a limit is rejected and shortened by the agent; fields over the recommended length are flagged.
Will it write for health or alcohol products?
For health it never promises treatment or guaranteed results. Promoting alcoholic drinks is banned in Turkey, so it explains this in the compliance note and only covers a lawful aspect such as the venue or food.
How many variants should I ask for?
Three to four variants are enough for an A/B test. Google responsive search ads work best with 10–15 headlines and 4 descriptions per variant.
