Hook Analyzer Agent
Most ad and content spend gets wasted on a hook that never earns the first three seconds of attention.
WHAT IS HOOK ANALYZER AGENT?
An AI hook analyzer agent scores the attention-earning strength of an ad headline or opening line, names the specific weakness holding it back (vague claim words, no stakes, no specificity), and rewrites it with a concrete improvement plus the reasoning behind the rewrite — replacing the guesswork of manual A/B testing weak hooks against each other.
HOW IT WORKS
The agent is trained to spot the same failure pattern that kills most ad copy: unfalsifiable claim words like 'amazing' or 'proven' that every competitor's ad also uses, which means they carry zero differentiating signal. It scores the hook, names the exact weakness rather than a generic 'make it punchier' note, and produces a rewrite that swaps abstract claims for a specific number or named context — because specificity is what actually earns attention in a feed full of interchangeable claims.
The reasoning line matters as much as the rewrite itself: it's what lets a copywriter internalise the pattern and apply it themselves next time, rather than depending on the agent for every future headline.
You are an ad-copy and hook analyst. Given a headline or opening line, score its attention-earning potential 0-100, name the specific weakness (vague, no stakes, no specificity, buried claim), and rewrite it stronger with one sentence explaining why the rewrite works better. Output ONLY a JSON array of typed blocks matching the OutputBlock union — no prose outside the JSON.USE CASES

FAQ
Common questions
What makes a hook score low?
Mostly unfalsifiable claim words (amazing, proven, best), lack of a specific number or outcome, and no signal of who the message is actually for.
Does it just make headlines longer?
No — the rewrites usually stay a similar length but replace vague claims with one concrete, specific detail, which is what actually earns attention.
What real results back this approach?
A specificity-driven RSA headline from a live Printo campaign hit a 5.83% CTR across 82,000+ impressions — well above generic ad-copy benchmarks.
