TikTok Caption Generator

Captions and hooks written for how people actually scroll.

Describe your video and TextAI writes the caption and the on-screen hook. It keeps captions short enough to read before the video loops, and can write three or four variations so you can pick the one that fits the edit.

  • In the app: TikTok caption
  • Works from the TextAI keyboard in any app
  • Accepts a photo or screenshot as input
  • iPhone, iOS 17+

Caption or hook, which matters more?

The hook. The on-screen text in the first second decides whether anyone stays long enough to read the caption. TextAI writes both: Write TikTok Hook for the opening line, TikTok Caption for the text under the video. Generate the hook first and let the caption support it.

How long should a TikTok caption be?

Short enough to read before the video loops, usually under 100 characters. Longer captions work when the text is the joke, but if the caption explains the video, the video is not working. TextAI defaults to short and expands only when asked.

Does it help with ideas, not just wording?

TikTok Video Ideas suggests concepts for a given niche, Write a TikTok Script drafts the whole thing, and Review TikTok Profile critiques what you already have. Trend Finder surfaces formats worth trying. The caption generator is the last step, not the first.

A word on hashtags

Two or three specific tags beat twenty broad ones. TikTok’s recommendation system reads the video and the caption text far more than the tag list, so effort spent on the first line returns more than effort spent stuffing tags.
