Last Sunday I decided to scratch my own itch.
Managing YouTube channels (and building in public on multiple platforms), I was drowning in comments. Questions getting buried. Feedback scattered. Patterns invisible.
So I built a comment analyzer. One evening. YouTube API + Gemini 2.0 Flash + my workflow engine.
What surprised me most?
Not the tech stack (that part was straightforward). It was discovering "Truth Gap" — the disconnect between what creators say and what audiences experience.
Example: Tutorial claims "simple 3-step setup." Comments full of "stuck at step 3" and "doesn't work on Windows."
That's a Truth Gap. And it's invisible until you analyze comments at scale.
Tested it on the first YouTube video ever — "Me at the zoo" (2005, 10M+ comments). Found fascinating patterns in 18 years of internet history.
Built the tool for myself. Turns out it solves a universal problem for anyone creating content.
Lesson: Best products come from solving your own pain points. Not market research. Not competitor analysis. Just building what you need and discovering others need it too.

Frequently Asked Questions
Why build this yourself instead of buying?
Most existing tools like TubeBuddy are great for SEO but weak on semantic analysis. I didn't want keyword density; I wanted to know what people are actually feeling.
How long did it actually take?
The core logic took about 4 hours on a Sunday evening. The "Truth Gap" prompt engineering took another 2 hours. That's the power of having a ready-to-go workflow engine (WRIO) underneath.
What was the hardest part?
Handling the sheer volume of spam in the comments. We had to implement a dual-layer filter (YouTube ranking + AI discernment) to get clean data.
Is the source code available?
We haven't open-sourced the full repo, but I shared the key architecture and prompt snippets in the technical deep dive.
Can I try it?
Yes, the tool is live and free during the beta. You can run your own analysis at wr.io/wrio/products/youtube-analyzer.
