Small tools for the jobs around a video — writing the hook, checking the framing, working out what a number means. They run in the browser, they are free, and none of them asks you to make an account. The full breakdown of a video is what Hookova itself does.

Coming soonYour audience's timezone spread turned into the posting windows worth testing first.

9:16, 4:5, 1:1 — exact pixel dimensions for any target frame, with the crop shown.
Coming soonDrop a frame in and see exactly what the TikTok, Reels and Shorts interfaces cover up.
Coming soonPer-platform character limits counted as you type, with hashtags tallied separately.
Coming soonSRT, VTT and plain text, converted both ways — in the browser, nothing uploaded.

Paste a TikTok, Reel or Short and Hookova returns a shot-by-shot storyboard — framing, camera, and the hook technique in each beat. Three analyses free.
