You already wrote a hook — spoken line and/or on-screen text.
About Hook Grader
Hook Grader is a free AI agent download on Capafy. You already wrote a hook — spoken line and/or on-screen text. Paste it with your platform (TikTok / Reels / Shorts) and get a 0-10 score on 4 things that decide the first 3 seconds: clarity, curiosity gap, specificity, and pace. Each score gets a one-line reason, plus the single biggest fix and one rewritten version. This only grades a hook you already have — it doesn't generate new hook ideas or a script. For 5+ hooks and a full script from a topic, that's a different agent (Hook Lab). It works only on the text you paste in; it does not log in to or post on your accounts.
