What is TikTok?

TikTok is a short-form video app that exploded to over a billion users because it’s simple, addictive, and insanely viral. You post a video, the algorithm shows it to the right people, and boom—your content takes off.

It’s not just dances and lip-syncs anymore. It’s a marketing machine, a creative playground, and a platform where everyday people turn into influencers overnight. If you’re not on TikTok, you’re leaving attention on the table.


How to Add Captions to TikTok Videos

Answer: You can add captions in the TikTok app by inserting text and manually setting its on-screen appearance, or you can use an online AI like SendShort which listens to your video and auto-generates captions.

Fear not, we’ll take you through both methods — starting with TikTok’s way.

  1. Auto-generated captions → These are auto-generated and often inaccurate. They can also disappear at any time.
  2. Manually add captions → This is plain text which you have to manually add and set the custom duration (meaning = how long it shows on the screen).
  3. Online auto-captioning for TikTok → The most efficient way is to use an online service like SendShort, which uses AI to add accurate subtitles to your TikToks (the best part is that it has many customization options).

Let’s take them one by one.


Method 1: Auto-Generated Captions

While TikTok’s method may not be 100% reliable, we’re going to show you the best method just after this one. On the other hand, TikTok’s method is really the quickest way to add subtitles.

1.1. Turn on Auto-Generated Captions

Answer: You can turn captions on/off within the TikTok app by long-pressing the video and selecting “Captions” to choose your preferred language.

  1. Open the TikTok app
  2. Find a video
  3. Long-press the screen
  4. Tap “Captions
  5. Toggle on “Show captions (auto-generated)
  6. Optional: Translate the video
Using the built-in TikTok captions feature

This works for any video individually.

If you opt for translating the video, TikTok can automatically translate it in over 25 languages.

1.2. Turn off Auto-Generated Captions

Answer: To disable TikTok’s captions, you have just to long-press the video, go to “Captions” and tick off the box for “Show captions (auto-generated)”.

This is the simple step-by-step process:

  1. Open the TikTok app
  2. Find a video and long-press it
  3. Tap “Captions
  4. Switch off “Show captions (auto-generated)
Turning off the auto-captions feature on TikTok

This will disable captions for all TikToks you’re going to watch.


Method 2: Add Captions Manually

Answer: The most efficient free, but rather complicated, method to add captions to TikTok is to manually insert them. To do this, you just have to insert text and manually set its length on the timeline.

Adding text to a TikTok video in the TikTok app

This is the step-by-step process:

  1. Open the TikTok app and tap “+”
  2. Record a video or Upload a file
  3. Click “Aa” on the right
  4. Type your text
  5. Swipe up to reveal the timeline
  6. Edit the text’s duration (e.g. Show from 0:14 to 0:17)
  7. Press “Done” > Upload the video

It’s a bit complicated, but it does the job if you don’t want to use another app but TikTok.


Method 3: TikTok Captioning Service

Answer: The most efficient and accurate way to add captions to your TikTok videos is through a free AI like SendShort, which automatically generates captions with +10 customizations.

Here’s how it works:

  1. Create a free SendShort account
  2. Upload your TikTok
  3. AI automatically adds captions
  4. Edit, delete, or add new captions to the video
  5. Download & Post on TikTok

This app adds subtitles on the video itself, and they cannot be turned off — unlike on TikTok, where you can turn off captions.

Why Add Captions to TikTok Videos

The main reason to add captions to a TikTok is to increase accessibility.

Overall, captions are an essential tool for maximizing engagement, accessibility, and visibility on TikTok, enhancing the overall viewer experience.

1. Makes your video more accessible

Captions make content accessible to viewers who are deaf or hard of hearing, ensuring that everyone can engage with your videos. This inclusivity broadens your audience and fosters a sense of community.

2. Retention of sound-off viewers

Many users watch TikTok videos without sound, particularly in public or noisy settings. Captions allow these viewers to understand and enjoy your content without needing to turn on the audio.

3. Improves engagement

Captions can help keep viewers focused on your content, encouraging them to watch all the way through. This increased retention can lead to higher engagement rates, such as likes and shares.

4. Reaches multi-language viewers

Captions can assist non-native speakers in understanding the dialogue better. By reading along while watching, viewers can improve their language skills and comprehension.

5. Captions have a role in TikTok SEO

TikTok may index captions for search purposes, making your videos more discoverable. Well-written captions that include relevant keywords can help your content appear in searches related to your niche.

2. Add hashtags

Incorporate relevant keywords and hashtags to improve discoverability. This helps your videos reach a wider audience and appear in searches related to your niche.

3. Use emojis

Emojis can make your captions more visually engaging and fun. They can help convey emotions and break up text, making your captions more eye-catching.
