Paste a hook to get started
We score on four dimensions — curiosity, specificity, brevity, emotion — and rewrite your hook in three proven copywriting frameworks.
How to use the score
The composite score is a weighted average across four dimensions. Curiosity and specificity matter most (~30% each), emotion is a strong second (~25%), and brevity is a gate — meeting it adds little, violating it tanks the rest.
When the score is below 65, fix the lowest-scoring dimension first. Most hooks fail on curiosity (no gap) or specificity (vague placeholders like "things", "people", "tools"). The reason text under each dimension tells you exactly what's missing.
Once you have a strong hook, browse the Hook Library for 100+ templates across 11 categories you can imitate, or read the AI Content Marketing Playbook for the full framework selection guide.
Why this is a heuristic scorer, not an LLM
Free tools are only useful if they stay free. Heuristic scoring runs in your browser at zero cost; an LLM call would force a signup wall (which kills the SEO and link-building value of the tool). Inside Content Drifter, the AI hook rewriter is LLM-powered, trained on your Brand Kit and your past posts. The free tool is the trailer; the dashboard is the movie.
