A hook for the first line
Viewers decide in a second whether to keep watching, so the caption opens with a short hook that matches the first frame of your video.

Short captions that suit TikTok
Captions stay short and easy to read over the video, with the key message first instead of a long block of text.
Focused hashtags
Get a small set of relevant hashtags placed at the end, instead of a long list of unrelated tags.
Prompts that invite comments
Each caption can end with a simple question or prompt so viewers have a reason to reply.
How it works
- Paste your video idea, script or rough notes.
- Keep TikTok selected — add other networks only if you want the same idea repurposed.
- Choose a tone and generate; you get a short TikTok caption with a hook and hashtags.
- Edit the caption, attach your video, then copy it into TikTok.
Repurpose the same post elsewhere
TikTok is the default here, but the same idea can be rewritten for X, LinkedIn, Facebook, Instagram and Telegram in the same run — each with its own length, tone and hashtags instead of one recycled caption.
TikTok caption FAQs
How long should a TikTok caption be?
Short captions usually work best, because viewers read them while the video plays. Put the main point in the first few words.
How many hashtags should I use on TikTok?
A few relevant hashtags are better than a long list. The generator keeps them focused and places them at the end.
Is the TikTok caption generator free?
Yes — you can generate TikTok captions in Universal Posting on the free plan, which includes monthly credits.
