Free AI TikTok caption generator
Describe your video and get a casual, hook-first caption you can paste straight into TikTok.
This free TikTok caption generator writes a short, casual caption from a description of your video. It leads with a hook, ends with a clear call to action, and stays within TikTok’s 2,200-character limit. Copy it into TikTok yourself; Orbin does not publish to TikTok yet. No account needed.
What a TikTok caption is for
On TikTok the video is the star and the caption plays a supporting role. It frames what viewers are about to watch, adds the keywords that describe the topic, and gives people a reason to comment, follow, or watch again.
The limit is 2,200 characters, but the best captions are usually a line or two. Viewers decide in a moment whether to keep watching, so a caption that reads like a quick aside from a friend tends to fit the platform better than a polished paragraph.
Hook, topic, ask
- Hook: open with the most intriguing line, a question, or a bold claim that matches the video.
- Topic: name what the video is about in plain words, since people also search TikTok for topics.
- Ask: end with one prompt, such as comment your answer, follow for part two, or tell me what to try next.
- Hashtags: a small, relevant set. Orbin’s AI aims for around 3–5, mixing a couple of broad tags with a couple of niche ones.
What to tell the tool
- Describe the video’s payoff in one sentence: the transformation, tip, joke, or reveal.
- Say who it is for, such as new home cooks or first-time founders.
- Pick an energetic or casual tone so the caption does not sound like an ad.
- Mention a trend or format only if your video really uses it.
Caption, on-screen text, and the spoken hook
Three things can carry your message on TikTok: the spoken or on-screen hook in the first seconds, the text that reinforces it, and the caption below the video. Let the video deliver the hook, then use the caption for what the video cannot show, such as the full recipe name, the ingredient list, the offer, or the next step.
If you repeat the same sentence in all three places, viewers have no reason to read the caption. Give each one a different job.
TikTok caption mistakes to avoid
- Writing a long, formal caption for a fast, casual video.
- Repeating the on-screen text word for word.
- Using hashtags unrelated to the video just to reach more people.
- Forgetting a call to action, so viewers watch and leave.
Using the caption with Orbin
Orbin does not publish to TikTok yet, so paste the caption into TikTok when you post. If you also share the same idea on Facebook, Instagram, X, or LinkedIn, Orbin can adapt it for each of those networks and schedule it from one calendar.
