Free caption generator for TikTok and Instagram
Describe your post and get five captions that add context, use the words people search for and end with a question that pulls comments.
What a good caption does
On short video the caption isn't the hook; the first second of the video is. The caption has three smaller jobs: give context the video can't, nudge people to comment, and put a few search words where TikTok and Instagram can read them.
- Context: who it's for or why it matters, in one line.
- A question: the easiest way to get comments is to ask for an opinion or a story.
- A search phrase: both apps match captions to searches, so name the topic the way people type it.
💡Read the first five words on their own. That's roughly what shows before "more", so they should make sense alone.
TikTok vs Instagram captions
| TikTok | ||
|---|---|---|
| Length that works | One or two short lines | Two to four lines; carousels can carry more |
| What it's for | Context and a comment prompt | Context, a takeaway, a reason to save |
| Hashtags | 3–5 niche tags | 3–5 niche tags, in the caption or first comment |
| Tone | Like a text to a friend | Slightly more polished, still personal |
Pick the platform above and the generator keeps to the right length. For more on tags, read the captions and hashtags guide.
Caption formulas to try
- Context + question: "Third apartment, first time I got the deposit back. What's your worst landlord story?"
- Takeaway + save prompt: "Slide 4 is the one nobody tells you. Save this for move-in day."
- Disagree bait (honest): "Unpopular opinion: you don't need a budgeting app until you have a budget. Agree?"
- Behind the scenes: "We almost didn't ship this feature. Here's why we did."
How to use the generator
- Describe the post in a sentence: the format, the topic and who it's for.
- Pick a tone and the platform.
- Copy the caption that sounds most like you, then edit a word or two so it's yours.
- Add 3–5 tags from the hashtag generator.
If you're making a batch of posts, UGCHooks writes the caption and hashtags for every one of them. Paste your product link and get 100 posts with captions in a CSV.
Questions
Is the caption generator free?
Yes, a dozen times a day with no sign-up.
How long should a TikTok caption be?
Usually one or two short lines. The video does the selling; the caption adds context and asks a question.
Should I put hashtags in the caption?
On TikTok, yes, 3–5 niche ones. On Instagram either the caption or the first comment works; keep it to a handful.
Will it make claims about my product?
It's told not to invent statistics, reviews or prices. Read each caption before you post it.
