Free TikTok Caption Generator

A TikTok caption generator writes the short text that goes with your video. Describe the video, paste your script or upload the clip, and Deepege writes caption options with a hook, a call to action and hashtags, then shortens or rewrites them in the same chat until one fits your account.

Mockup: one latte video with three TikTok captions labeled hook, question and call to action

Captions that start with a hook

Only the first line of a TikTok caption shows before people tap to read more, so it has to back up the first second of your video. Ask for three options and Deepege writes three angles on the same clip: a hook, a question and a direct call to action. Set a length limit, add or drop emojis, and keep the one that sounds like your account.

Written from your script or your video

Already have the voiceover script? Paste it into the chat and Deepege writes a caption, a longer description and hashtags that match what you actually say. You can also upload the video file (MP4, MOV or AVI): Deepege transcribes the speech first, then writes the captions from the transcript, so nothing in the caption contradicts the video.

See what is working on TikTok first

Before you write, ask Deepege to search TikTok for popular videos on your topic, or to list trending searches and trending hashtags for your market. It shows the real videos and numbers it finds, so you can see which hooks and formats people respond to, then turn that into captions for your own video.

How to use

1
Describe your video
Say what happens in the video, who it is for and what you want viewers to do. Paste the script or upload the clip if you have it, or edit the sample prompt above.
2
Pick a caption
Deepege writes the options you asked for, with hashtags. Ask for more ideas, a different hook or a shorter length at any time.
3
Polish and post
Ask for changes in plain words, such as another language or fewer hashtags, check the facts, then paste the caption into TikTok.

Used across industries

Online store example: a TikTok of a lit cedar candle with a caption about the Friday restock and link in bio — Online stores and product brands
A candle shop posts a 12-second clip of its cedar and fig candle being lit and wants a caption that sells without sounding like an ad. Deepege returns short captions that lead with the scent, mention the Friday restock and point to the link in bio.

Real estate example: a TikTok house tour of a three-bedroom home with a caption asking viewers to comment tour — Real estate agents
An agent films a 30-second walkthrough of a three-bedroom home and wants people to watch to the end. The caption teases the best room, names the neighborhood and asks viewers to comment "tour" to get the details.

Bookstore example: a TikTok of a shelf of fall reads with a caption asking followers for their pick — Bookstores and BookTok creators
A bookstore films a shelf of fall reads and wants comments, not just views. Deepege first looks at popular #booktok videos, then writes captions that ask followers for their pick and adds hashtags that fit the post.

What makes a good TikTok caption

On TikTok the video does most of the work, and the caption gives people a reason to keep watching, comment or follow. A caption that works usually has:

A hook that matches the video: the same promise or question as the first second of the clip, so the caption and the video pull in one direction.
The key detail up front: the offer, the place or the product name in the first line, because the rest is hidden until people tap.
One clear ask: comment, save, follow or tap the link in bio. One ask works better than three.
Your account's voice: casual, funny or expert, the way your followers already know you.
A few relevant hashtags: tags that describe the video and your niche. For more hashtag ideas, use the TikTok hashtag generator.

TikTok caption ideas by video type

Product videos: lead with what the product does for the viewer, then say where to buy.
Tutorials and recipes: say what people will be able to do by the end, and ask them to save the video.
Tours and before-and-after videos: tease the best part so people watch to the end.
Behind the scenes: one personal detail about the people or the process.
Offers and events: date, time and offer in the first line.

How this tool works

Edit the prompt above with what your video shows, the goal and the length you want. After you sign in, Deepege opens a new chat and sends your prompt, and the captions appear in the chat. Ask for changes, more options or another language until one fits, then copy it. Still planning the video? The video script generator writes the hook, scenes and voiceover first.

FAQ

What is a TikTok caption generator?

It is a tool that writes the text that goes with a TikTok post. On this page you describe the video, paste its script or upload the clip, and Deepege chat writes caption options with a hook, a call to action and hashtags that you can edit by chatting.

Is this TikTok caption generator free?

Yes, you can try it for free. You get free credits on sign-up, so you can open Deepege chat from this page and write captions right away. When the credits run out, you can keep going on a paid plan.

Can it write a caption from my video?

Yes. Upload the video file (MP4, MOV or AVI) in the chat and ask for captions. Deepege transcribes what is said in the video and writes the captions from the transcript. If you already have the script, paste it instead.

Does it add captions (subtitles) on top of the video?

This page writes the text caption that goes with your post. On-screen subtitles are a separate step: if you make the video in Deepege, subtitles can be added while it is being edited. For a video you finished elsewhere, use TikTok's own caption tools or your editing app.

How long should a TikTok caption be?

There is no single right length. Only the first line or two show before people tap to read more, so put the hook and the key detail first. Short captions suit most videos; tutorials and stories can use a longer one. Tell Deepege the length you want.

Can I use the captions for my business?

Yes, you can use them in your own marketing. Check facts such as prices, dates and product claims before you post, and see the Deepege user agreement for details.
