Video to YouTube Timeline App

This is a submission for the AssemblyAI Challenge: Sophisticated Speech-to-Text.

What I Built 🎥✨

Ever struggled with making YouTube video timelines? Like, who has the time to sit down, rewatch their entire video, and write timestamps? Not me! That’s why I built Video to YouTube Timeline, an app that does it for you.

How It Works:

1. Upload Your Video: Toss your video file into my app like it’s a hot potato.
2. Audio Extraction: My app pulls out the audio faster than you can say “AssemblyAI.”
3. AI Magic: That audio gets sent to AssemblyAI, where their super-smart Universal-2 model listens carefully and says, “Here’s what’s going on!”
4. Timeline Generation: The app turns the AI’s notes into a perfect YouTube timeline format you can copy-paste into your video description. Boom, done. 🎉

Coming Soon: You’ll even be able to link a YouTube video directly (no upload required). Just link it, get your timeline, and flex on how fast you got it done.

Journey 🚀

So here’s the tea ☕: I wanted to make something cool with AssemblyAI, and I thought, “What do YouTubers need?” A timeline generator, of course!

The app uses AssemblyAI’s Universal-2 Speech-to-Text Model, which basically listens to your video’s audio and generates chapters based on what’s happening. I made sure the output is YouTube-friendly, so you don’t have to format anything. Copy. Paste. Done.

Key Features:

• Super-fast audio processing (because nobody likes waiting).
• Accurate chapters that make you look like a pro.
• Coming soon: Direct YouTube video linking (it’s gonna be 🔥).

What’s Next? 🛠️

1. YouTube Linking: Just link your video, skip the upload, and let the app handle the rest.
2. Edit Chapters: Want to tweak those chapter names? Soon, you’ll be able to.
3. More AI Coolness: Who knows what else we can automate for creators?

Why AssemblyAI? 🤖

Because their Universal-2 model is smart, fast, and gets the job done without breaking a sweat. (I’m convinced it’s cooler than me.)

Team 💻

It’s just me. A one-person army. If something breaks, blame me, too. 😅

Fun Fact 🎉

Building this app made me realize that AI doesn’t just listen better than me—it’s also more productive. Go figure.
