AI TikTok Caption Generator
Describe your video and let AI write scroll-stopping captions and hooks that earn watch time and shares.
What is the AI TikTok Caption Generator?
On TikTok, the caption reinforces the hook and tells the algorithm what your video is about. Describe your video, choose a style — viral hook, how-to, promo or trend — set the vibe, and the AI writes punchy captions with hashtag ideas so your video gets categorized and served to the right For You feeds.
It's free and unlimited. Generate, tweak, and paste it into TikTok.
How to write a TikTok caption
- Describe your video and the payoff viewers get.
- Add a few hashtag keywords (mix broad and niche).
- Pick a style and set the vibe, then click Generate Captions.
- Browse the hooks and choose the strongest.
- Personalize it and post to TikTok.
Tips for better results
- Curiosity beats summary — tease the payoff instead of explaining the whole video.
- Mix one broad hashtag with two niche ones so you land in the right sub-communities.
- Add a 'save this' or 'follow for part 2' to boost saves and follows.
- Keep captions short; TikTok truncates fast and the video is the star.
