The short answer

Submagic is the best tool I've used for punchy short-form captions: it nailed the captions, keyword highlights and emojis on my YouTube Short in under 5 minutes. Plans start at $19 a month, or $12 a month billed yearly, for 15 videos up to 2 minutes long, and you can test it free on three videos. It's built for TikTok, Reels and Shorts creators, not long-form editors.

In this article, I wanted to provide a genuine review based on my personal experience with Submagic’s AI captions.

Rather than simply listing features and pretending it’s great, I created an original YouTube Short and used Submagic’s AI captions for the subtitles.

Then I uploaded the finished Short to YouTube. 🙂

If you want the TLDR: yes, Submagic is worth it for AI captions, especially if you make short-form video.


5 Unique Submagic Features

Before we start, let’s take a quick look at 5 of Submagic’s most useful and unique features.


  1. Super Accurate Captions: Submagic uses advanced natural language processing algorithms to generate accurate video captions. It now advertises 123 languages, up from 48 when I tested it.
  2. Trending Templates & Emojis: Content creators can enhance their videos with the latest trending templates and use auto emojis to emphasize key points.
  3. Magic B-Rolls & Transitions: Submagic adds stock B-roll and transitions in one click to enhance your narrative (Storyblocks footage comes with the Pro plan and up).
  4. Magic Auto-Zooms & Auto-Cut: Submagic automatically adds zooms to highlight important moments, and its AI auto-edit cuts out silences and bad takes.
  5. Auto Descriptions: The platform writes a description for your post automatically, helping creators boost their reach and engagement.

Since I tested it, Submagic has also added Magic Clips (which cuts long videos into shorts), AI avatars (Submagic calls them AI Actors), eye contact correction, video translation and a scheduler for posting straight to your socials.

Let’s get into the fun stuff. 👇

Submagic Review: How I Made a YouTube Short With Submagic

What better way to review Submagic than to actually use it to add captions to an original YouTube Short!?

In this article, I’ll walk you through the entire process of using Submagic to create captions on a YouTube Short so you can see exactly how it works.

Heads up: Submagic has added a lot of features since I took these screenshots, so your editor will look a bit different, but the workflow is still upload, tweak and export.

Let’s learn how to create captivating subtitles with Submagic's must have tool. 👇

Step 1 - Sign Up

Head over to Submagic and sign up.

You can try it free on three short videos before you commit, though exports carry a Submagic watermark until you subscribe.

When I signed up, the Basic plan (monthly) got you 20 videos per month for $20.

Trust me when I say: When you see how much time Submagic saves in video editing and manually adding captions, $1 per video is excellent value.

Submagic's pricing table from when I tested it, before the plans changed

The plans have changed since that screenshot. Here’s what Submagic charges now:

  • Starter: $19 a month, or $12 a month billed yearly, for 15 videos a month up to 2 minutes long, exported in 1080p.
  • Pro: $39 a month, or $23 a month billed yearly, for 40 videos a month up to 5 minutes long, plus Storyblocks B-roll and auto zooms.
  • Business: $69 a month, or $41 a month billed yearly, for 100 videos a month up to 30 minutes long, with 4K exports at 60fps.

The entry plan was enough for me, but if you plan on doing more than 15 videos a month, or anything longer than 2 minutes, step up to Pro.

Step 2 - Upload Your Video File

Let's get into the fun stuff - it's a game changer.

Drag and drop your video content into Submagic to get started with the upload.

Once the video file uploads, Submagic's artificial intelligence wastes no time and begins transcribing audio straight away.

Step 3 - Tweak Your Captions

I'm not lying when I say, I'm really impressed with the captioning process.

Straight outta the box, Submagic's AI intelligently highlighted keywords and generated accurate captions with relevant emojis. ✅

There were a few minor changes I made to the words but that was the only changes needed to the subtitle animations!

To give you an example, at one point the AI mistook the word 'Elon' for 'long'... but that could have been my muffled voice's fault! 🤣

From there, I played around with the 8 caption styles available at the time.

I was tossing up between Hormozi and Devin style but ended up going with 'Hormozi2' captions.

It's at this time you can use the AI tools to tweak the caption colors, size, and Y position too.

Another great feature of Submagic is the static caption and hashtag generator in the third column.

Step 4 - Save and Export

We're done already! Save your project and click export.

Video editors reading this should know how simple this is compared to manually creating captions in Premiere Pro and DaVinci Resolve.

The export took a minute or two, and Submagic emailed me when it was complete - super handy.

The finished Short came out with captions that punch up the key points, which is exactly what you want for viewer engagement.

The Verdict on Submagic

Submagic is a top choice for artificial intelligence generated captions that feature automatic emojis and premium B-roll.

The tool offers multiple caption styles for your video content and simple editing features.

While it's excellent for short-form content creation, videos longer than 2 minutes need the Pro plan (up to 5 minutes) or Business (up to 30 minutes).

Ideal if you're wanting to create captions on Instagram, YouTube, and TikTok and are aiming to boost viewer engagement.

As someone who previously spent hours manually adding captions in Premiere Pro, I can confidently say that Submagic is the best AI caption generator I've used.

It took me less than 5 minutes to upload my video, make a few tweaks, and export the final take complete with intelligently highlighted keywords and automatically generated emojis. 🤯

If I wanted to create captions with perfect emojis and highlighted keywords like the ones Submagic generated in just a few clicks, it would have seriously taken me a few hours in Premiere Pro.

Submagic has kept adding features since I tested it: Magic Clips for turning long videos into shorts, AI auto-editing that cuts silences and bad takes, AI avatars, eye contact correction, video translation and a built-in scheduler for posting straight to your socials.

If you want to compare it with other tools first, I've rounded up the best Submagic alternatives.

For content creators looking to save a massive amount of time, increase viewer engagement, and automatically create world class captions in literal seconds, Submagic is a no brainer.
