The score (0-100) combines 13 engagement signals: power words (+10 each, max 3), numbers (+8 each, max 2), starting with a number (+8), question (+7), open loop/cliffhanger (+7), pattern interrupt (+8), emojis (+5 each, max 2), optimal length (+5), personal pronouns (+5), story opener (+6), contrast/tension (+5), specificity (+5), and urgency (+4). Penalties apply for excessive caps (-10) and over 80 characters (-5). When you select a specific platform, a platform fit bonus adjusts the score further.
It does two things. First, it shows you exactly where that platform truncates your hook in the feed (e.g. LinkedIn at 140 chars, X at 90 chars). Second, it adds a platform-specific scoring bonus. For example, LinkedIn rewards authority language and questions, X rewards brevity, Instagram rewards emojis and curiosity, TikTok rewards pattern interrupts and short hooks, and Threads rewards concise conversational hooks.
The tool auto-detects which type you are writing: Contrarian (debunk myths), Big Idea (reframe thinking), Curiosity/Open Loop (create cliffhangers), Case Study (prove results), Authority (leverage credibility), Transformation (before/after), Educate (how-to/frameworks), Inspirational (motivate action), Stats/Data (use numbers), Emotional (trigger feelings), Funny (humor/self-deprecation), and Newsjacking (leverage current events).
No. Everything runs entirely in your browser. Your hook text is never sent to any server.
High-impact terms proven to increase engagement — words like "secret", "proven", "free", "mistake", "ultimate", "hack", "game-changer", "brutal", and about 30 others. They trigger curiosity and emotional responses.
A pattern interrupt is a word or phrase that forces the reader to stop scrolling. Starting your hook with "STOP", "DON'T", "Wait", "Warning", "Unpopular opinion", or "Hot take" triggers an immediate scroll-stop response. The tool detects these and awards +8 points.
An open loop is a curiosity gap that makes people need to keep reading. Phrases like "Here's why...", "Here's how...", "You won't believe...", or using an ellipsis (...) create open loops. The tool detects these patterns and awards +7 points.
Type two hooks side-by-side. Both score in real time. The higher-scoring version gets a green border and Trophy badge. The tool also shows the point difference so you know how close they are.
