“It told me which second my hook died. Brutal, and exactly what I needed.”
“I stopped guessing why videos flopped. Now I see it before I post.”
“The rewrites are the product. I shot one and retired my old opener.”
Drop a TikTok, Reel, or Short. mp4, mov, or webm — any length.
We dissect the first three seconds against a 7-dimension forensic rubric.
You get the exact failure points and five rewrites you can shoot today.
“The algorithm decides in under a second. Most creators never find out why they lost.”
TikTok, Reels, and Shorts all judge your video on the first 600 milliseconds. Drop below their retention threshold and you don't get a second chance. HookLab is the only tool that tells you, frame by frame, exactly what the algorithm saw.
