A hook analyzer scores the first line of your video — the opening seconds that decide whether someone keeps watching or scrolls past. Paste your hook and get feedback on its strength so you can rewrite it before you record, not after it underperforms.
On short-form platforms, the hook is everything. The first one to three seconds set your retention curve, and retention is what the algorithm uses to decide how far to push a clip. A weak opening caps the ceiling of even a great video; a strong one gives an average video room to travel.
This free tool helps you pressure-test hooks fast — no signup. Use it to compare variations and pick the opener most likely to stop the scroll.
