TikTok hook analyzer
Paste a TikTok link. See the hook from its first 3 seconds, the format, the call to action, and plain reasons the video worked.
Any public TikTok video. Free, no sign-up, up to 5 videos a day.
How to use it
- Find a video that did unusually well for its creator: many more views than their other posts, not just a big account’s normal day.
- Copy its link from the share menu and paste it above.
- Read the hook and the reasons, then write your own version: same kind of opening and format, your topic and your voice. Copying the words doesn’t work; copying the structure often does.
Hooks that keep showing up
- A bold claim most viewers disagree with, so they stay to argue.
- A question the viewer already asks themselves.
- A number that promises a short, finite payoff (“3 mistakes…”).
- Talking to the viewer (“If you run a coffee shop…”), which picks the audience in one line.
From one video to your whole niche
One video is a hint; a pattern across a niche is a plan. postpeg finds the breakout videos in your niche every day, breaks them down, posts your version to TikTok and tells you where it landed. See TikTok competitor analysis and how it works.
Questions
- What is a TikTok hook?
- What the video says or shows in its first few seconds to stop the scroll. The analyzer takes it from the transcript’s first 3 seconds, or from the caption when nobody speaks, and names its type: a question, a bold claim, a number, a story, talking to the viewer, or something visual.
- How does it know why a video worked?
- It reads the transcript and caption, sorts the video into a format (tutorial, list, review, before and after, skit, POV, talking head) and finds the call to action, then writes two to four short reasons tied to those. It doesn’t watch the pictures, so treat it as a strong first read.
- Is it free? Is there a limit?
- Yes, free with no sign-up, up to 5 videos a day per person, with a daily cap across everyone. Each analysis fetches the video’s real data, so the limits keep it free. A video someone analysed in the last 30 days comes back instantly.
- Which videos work?
- Any public TikTok video link, in any language. Private, deleted or age-restricted videos can’t be read.
- Can I get this for a whole niche automatically?
- Yes. postpeg watches your competitors, keywords and hashtags daily, ranks the videos doing far better than their creator’s usual, and breaks down the best ones for you or your AI agent, with a weekly report. The trial is free for 7 days.
