Tool 555 · hook mechanism + delivery contract
Hook Generator
Generate hooks by mechanism—not by spinning the same sentence twenty times. #555 creates benefit, question, problem, specificity, observation, contrarian, story, proof, mistake, myth, challenge and list-style openings, then checks length, clickbait risk, claim integrity and whether the hook is actually supported by the content that follows.
12 hook mechanismsDifferent psychological entry points rather than cosmetic rewrites: benefit, tension, specificity, story, proof, myth, mistake and more.
Hook → body contractPaste what the post/video actually delivers. The tool flags hooks that promise ideas not supported by your body points.
Spoken + text planningPreview approximate spoken seconds for video and a conservative first-line character target for text formats.
Clickbait guardFilters unsupported “secret,” “guaranteed,” “shocking,” “everyone” and similar hype unless you explicitly disable strict mode.

Proof integrityNumbers, credentials and outcomes are only eligible when you typed them into the brief.
No fake “viral score”Quality numbers are local structural checks for clarity, fit, support and hype risk—not predictions.
