"TikTok caption" means two things, and Exemplary AI makes both.

For the post caption, paste the video's link (TikTok links import) and ask Emmy to write one from the transcript; the Keywords document adds hashtags. For captions on the video, start a captions project, pick the TikTok style and export the MP4 with them burned in. TikTok's developer documentation gives 2,200 characters as the limit for a video caption. The Free plan includes 500 one-time credits; files up to 500 MB and 30 min long; 720p video exports with a watermark. Credits are used by the tasks you run, rather than a fixed number of generations.

How it works

How to make TikTok captions

A TikTok video imported by its link, with Emmy open beside the transcript

Post caption or on-video captions?

The post caption is the text under your video: what the video is about, a reason to watch to the end, and hashtags. On-video captions are the words on screen, for the many people who scroll with the sound off. Most creators want both, and both come from the same transcript, so they agree with each other.

Browse the caption looks on the caption styles page, check the frame on TikTok video size, or get the words of any TikTok with the TikTok transcript generator. Starting from a YouTube video? See YouTube to TikTok.

What it does

Both TikTok Captions from One Video

One upload or link gives you the words for the post and the words on the video.

A post caption from what you say

Emmy writes the caption from the transcript, so it describes the video you actually made.

Hashtags from the video

The Keywords document's hashtags come from the same words.

The TikTok caption style

On-video captions in the TikTok style, or any other style in the library, burned into the MP4.

Edit before you post

Change any word in the drafted caption or in the on-video captions before you download.

Questions

Common questions

How do I write a TikTok caption with AI?
Paste the video’s TikTok link into Exemplary AI or upload the file. When the transcript opens, ask Emmy for a TikTok caption with hashtags; it drafts one from what you say.
Can it add captions on the TikTok video itself?
Yes. Start a captions project, choose the TikTok style (or another), correct any word, and export the MP4 with the captions burned in.
How long can a TikTok caption be?
TikTok's developer documentation gives 2,200 characters for a video caption; TikTok's help center does not list a number. Put the words that matter first.
Does the Social posts document include a TikTok caption?
No. Social posts writes for X, LinkedIn and Instagram. For TikTok, ask Emmy, or use Custom content with your own instructions.
Can it post the caption to TikTok for me?
No. Copy the caption into TikTok when you post; nothing is posted for you.
Is the TikTok caption generator free?
You can start on the Free plan: 500 one-time credits; files up to 500 MB and 30 min long; 720p video exports with a watermark. Transcribing, chatting with Emmy and exporting captioned video use credits.
