TikTok ads are won in the first second and watched on mute. LaunchReel takes a product description and returns five 9:16 variations, each front-loading the hook, with burned-in captions and a music bed already in place — sized and paced for In-Feed Ads and Spark Ads. Your first video is free, no credit card.
Every export from LaunchReel already meets these.

One or two sentences — what it is, who it is for, the main benefit.
The AI writes the hooks, generates footage, adds captions, voiceover and music.
Tune the cut in the browser editor, then export to spec for your placement.
Every variation opens on the hook — no logo intro, no slow build — because that is how TikTok is scrolled.
Word-level captions are positioned to stay readable above the caption text and away from the right-side action rail.
Post the set over a few days or run them as Spark Ads and let performance pick the winner.
Swap the hook line, trim the intro or change the track in the editor and re-export in minutes.
