About
Munch
Munch wants to find the viral moments hiding in your long videos. Upload your content, let the AI analyze it, and boom—you get a collection of short clips it thinks will blow up on social. It even tells you why it picked each clip, which is pretty cool for learning what works. If you're drowning in content and need to feed the social media beast, Munch is your lifeguard.
The thing is, viral according to AI might not mean viral for YOUR audience. The algorithm doesn't know your brand voice or your community's inside jokes. You'll probably spend time sorting through its picks to find the real gems. It's more like having an eager assistant than a seasoned social media manager. So what works better for you: AI efficiency or human intuition about what your audience actually wants? For more control over viral content creation, check out tools that combine YouTube Shorts creation with customizable AI hook generation tailored to your audience.

Zubtitle is a video captioning tool that helps creators add subtitles, headlines, and resize videos for social media.
About
Zubtitle
Zubtitle keeps it simple: your videos need captions, and most people watch with sound off anyway. Upload your video, let it transcribe, tweak the captions if needed, and choose from their pre-made styles. Throw in some headlines, progress bars, and resize for different platforms—done. It’s the no-nonsense approach to making your videos social-media ready with captions.
But here’s the thing—simple means simple. You won’t find cinematic transitions, layered b-roll, or more nuanced editing tools like fine trimming. It does captions and basic optimization, period. If that’s all you need, you’ll love how fast it is. If you’re chasing storytelling depth or a more polished final product, this probably won’t be your endgame editor.

The potential of Munch and the ease of use is why I upgraded. This is a powerhouse app.
Accidentally signed up for the annual subscription when I meant to sign up for the monthly subscription. I reached out to customer support about this issue and they resolved it very quickly. I'm very satisfied with the support I received for this issue and I'm excited to continue using Munch for our marketing purposes.
I was recommended to try this by Tony Robbins business mastery. Even though my friend said he had issues with site I still gave it a shot, I did the free version, and of course I needed the upgraded version once I uploaded video, I added some crappy B roll that AI suggested (not useful) and then from that point on website froze on my. I thought it was my connection but nope it was just that site. I probably went back another 2 or 3 times and it would again completely freeze on me. As a busy business owner I don't have time for this. I requested my money back and they refused. The lady Diana accused me of asking for my videos back. Could care less about anything I uploaded. I just think I puked$45 out the window.

Very easy to use. You get two free video credits with their watermark. You have the option to upgrade straight away or you can trial it using the credits
The ease of use for Zubtitle is incomparable. And trust me, I have made some comparisons.
It is very quick and easy to enhance our videos to a social media format, with headline and clear subtitles. I wish it was easier to change the colors.

Frequently asked questions
How does an AI clip maker work?
An AI clip maker scans long-form videos or podcasts using artificial intelligence to automatically identify the most engaging moments, then slices them into short clips with captions, animations, and transitions. It's a powerful way to repurpose content for platforms like TikTok and Instagram.
One thing to note is that an AI clip generator is not necessarily an AI video generator.
Can AI-generated videos be monetized on YouTube?
Yes, as long as your AI-generated videos follow YouTube's monetization guidelines and add original value—like commentary, visuals, or voiceovers—you can absolutely monetize them. AI tools help you create faster, but your creativity is still the magic ingredient.
How do I add a text-to-speech voiceover?
Most AI video editors have a text-to-speech option built in—just type your script, choose your AI voice, and click generate. It’s an easy way to add professional voiceovers to explainer videos, product demos, or tutorials without recording anything yourself.
How does text-to-video AI work?
Text-to-video AI turns written text prompts into fully edited video content—complete with visuals, animations, subtitles, and voiceovers. It automates video production so creators can go from script to video clips in minutes instead of hours.
How to switch the AI Avatar’s voice category?
Most AI avatar tools have voice categories based on tone or language—you just head to the voice settings and pick a different category (like professional, energetic, or friendly). It’s like casting the perfect voice actor, but instantly.
What are the top AI tools for generating video clips?
Top AI tools like Submagic, Pictory, and Descript make it incredibly easy to generate short clips from long-form content.
