Why people use it
Built for portrait Reels first. Works for TikTok and Shorts too.
Fit the slot
A 15-second ad holds roughly 35 to 40 words at a natural pace. The calculator tells you how much to cut before you record.
Three paces
Calm, natural and fast reads, because a talking-head ad and a punchy meme ad are not read at the same speed.
Hook check
Shows how long your first line takes, so you know the hook lands in the first two seconds.
