Suppose you’re looking at your screen with a brilliant idea in your head, but your fingers are frozen. Footage is ready, your energy is high, but you don’t know how to begin your video.
No hook, no caption, no tagline. It happens to all of us. That’s where CapCut App’s AI video maker tools come into the picture.
These intelligent tools are capable of assisting you to come up with such attention-grabbing opening lines, scroll-stopping subtitles, and striking taglines that prove worthy of attention right from start to finish.
Regardless of whether you’re a content creator, a business owner, or simply establishing an online brand, you don’t have to worry about the first sentence anymore. AI can assist, you can still keep your ideas at the center of your content.

Why the first line matters more than anything else
You have around three seconds, possibly less, to persuade someone to continue watching. That first thing you say (or present) is what hooks them. It doesn’t need to be dramatic. It just needs to be curious-sparking or emotionally connecting. Something like:
- ‘Nobody mentions this, but…’
- ‘Before you scroll, let me show you something…’
- ‘This error took me months—do. Don’t do it.’
These are the kinds of hooks that AI software can help you create, at the click of a button. You input your subject, and the AI presents you with a range of options, some punchy, some witty, some blunt.
Turn basic ideas into captions that work
Once you’ve got your hook down, the second task is making your message shine even when the sound is off. That’s where subtitles and captions save the day.
Many people move through content without sound or audio. So if your video depends on people hearing what you deliver, you might be losing the majority of your audience.
Captions solve that. And you don’t have to write them all one by one anymore. Thanks to tools like CapCut, you can generate your full subtitle track in a few seconds. Let’s break that down…
How to generate auto captions in CapCut

CapCut App’s AI caption generator hears your audio, identifies the language, and automatically generates matching captions for all words spoken.
Play in different styles and tones using the AI lab
Each video has a personality of its own. Some are playful, some are serious. Some are emotional, some are informative. The actual challenge isn’t necessarily crafting a sentence, it’s crafting the right one for your people.
That’s where an AI lab truly excels. It’s like having a virtual writing assistant who never becomes fatigued. You input your subject or message, and it produces multiple iterations of that message in various tones.
Need something cheeky? Use a joke-type hook. Need something darker? Use a fear-based opening. Require a caption for a product launch? Have the AI propose a dramatic pause or a surprise twist. You still decide what to use. The lab just offers you alternatives that you may not have considered yourself.
Here’s how:
Step 1: Access AI story maker

Open the CapCut App and tap the ‘AI Lab’ tab at the bottom menu. This area contains smart tools like ‘AI story maker’, ‘AutoCut’, and ‘AI tools’ designed to simplify content creation. Select ‘AI story maker’ and hit the ‘Try now’ button to begin.
Step 2: Input and customize

Type or paste your blog summary into the ‘Create AI story video now’ input field. Pick matching visual effects from styles like Realistic Film, Cartoon 3D, or Anime. Add a ‘Voiceover’ to narrate your summary and adjust the ‘Video ratio’ as needed. Tap the ‘Generate’ button to produce your visual blog clip.
After it’s generated, you can enhance it further. Add background music from the ‘Music’ section. Personalize your captions through ‘Caption style’ where you can apply animations, effects, and tweak fonts. For deeper editing, tap ‘Go to Edit’ to open CapCut’s full editor suite.

Once your video is ready, hit ‘Export’ in the top-right corner to save it to your device. You can then post it directly to TikTok, YouTube, Facebook, Instagram, or other platforms.
Examples of how AI can write for you
Suppose you are creating a video on selling homemade candles online. Without assistance, you may start with:
‘Hey, I sell candles, here’s how.’
But with the assistance of CapCut’s video generator, you may receive suggestions such as:
- ‘What if your room smelled like confidence?’
- ‘I hated my 9-to-5, now I sell candles that pay my rent.’
- ‘This $5 candle took me 300 hours to get right.’
Each sentence does something unique. Some generate interest, some connect with feelings, and some tease the rest of the story. You didn’t need to come up with all that on your own, but it still reads like you.
What makes this useful (especially for solo creators)
When you’re doing it all yourself, writing every post, every caption, every video, it’s draining. Even if you are creative, the amount of content that it takes to remain online can exhaust you.
This is where AI doesn’t steal your thunder, it defends it. By not wasting time on little things (such as rephrasing captions or revising a hook 10 times), you can dedicate more time to the idea itself. You’re not cheating. You’re working smarter.
Final thoughts: when you’re lost for words, let AI help you find them
No one’s a creative 24/7. There are days when things flow and days when you’re looking at the cursor for 20 minutes in a row. But now, you don’t have to do it alone. AI tools assist you when you get stuck.
They provide intelligent opening lines, plain language captions, and subtitles that make your videos more enjoyable to watch and share. The great news? You still sound like you. Just a little more rapidly, and much less stressed.
