First Impressions
Blackbox feels like a specialized search engine for code. I searched for 'React useEffect fetch example', and it gave me the code snippet immediately without the fluff of StackOverflow.
Best Feature: Video Search
Uniquely, it indexes coding videos. If a concept is hard to explain in text, it finds the exact timestamp in a YouTube tutorial. That's a niche but useful feature.
The Verdict
It's a solid utility. I find myself using it less now that ChatGPT has improved, but its VS Code extension is still convenient for quick lookups.
