AI Video Hook Optimizer

Give it a topic, trend, product, or niche. Get back scroll-stopping hooks and a short-form script built to win the first three seconds — not generic advice.

✨ What it does

It writes the part of your video that decides retention: a positioning angle, trend-informed topic ideas, 5+ first-3-second hooks (spoken + on-screen text, tagged by type), a recommended pick, a beat-by-beat script, and a caption with hashtags.

🎯 When to use / Best For

  • Your videos start slow — get openers that stop the scroll in 3 seconds.
  • You want to A/B hooks — 5+ distinct hook types for the same topic.
  • You film often — turn a rough idea into a ready script in one pass.
  • You sell or grow on short-form — hooks aimed at saves, follows, or sales.

⚙️ How it works

1️⃣ Position — the angle/POV your account should own for this topic.
2️⃣ Hook — 5+ first-3-second options, each with spoken line, on-screen text, and hook type.
3️⃣ Script — recommends the strongest hook and writes a beat-by-beat script with timecodes.
4️⃣ Caption — a caption with a CTA and relevant hashtags + a filming tip.

👤 Who it's for

Short-form creators, founders, marketers, and social teams on TikTok, Reels, and Shorts.

🧪 Example

You send: "Hooks for a 30s TikTok about why most people quit the gym in January — energetic, for beginners."

You get back (shortened):

  • Positioning: "The gym isn't the problem — your first week is." You own the beginner-who-keeps-quitting angle.
  • Hooks (5+, each with spoken line + on-screen text + type):
    1. Contrarian — 🗣 "Stop going to the gym every day." / 🖥 "Day 1 is where you quit"
    2. Question — 🗣 "Why does everyone quit by January 20th?" / 🖥 "The January 20th wall"
    3. Mistake — 🗣 "You're not lazy. You're doing week one wrong." / 🖥 "Week 1 mistake"
  • Recommended pick: #3, with one line on why it fits a beginner audience.
  • Script: 0–3s hook · 3–10s the mistake · 10–22s the fix in 3 steps · 22–30s CTA.
  • Caption: short caption + CTA + hashtags, plus one filming tip.

❓ FAQ

What should I send? A topic, product, trend, or niche, plus the platform (TikTok / Reels / Shorts) and the video length if you know it.

Does it watch my videos or log in to my accounts? No. It works only from the text you send. It does not post, read analytics, or connect to any platform.

How many hooks do I get? At least 5 per request, in different hook types so you can A/B test them.

Can I ask for changes? Yes — reply in the same chat (e.g. "make #2 funnier", "shorter script") and it revises.

Which plan should I pick? Day for a one-off batch, week for a filming sprint, month or year if you post every week.
