Putting Manus AI to the Test: Building a REAL AI Chrome Extension (Does It Actually Work?)

Is it possible to build a truly useful, AI-powered application with just prompts? In this video, we put Manus AI, a platform that claims to build full apps in minutes, to the ultimate test.

We're not just building a simple demo. We start with Manus AI's own "Academic Word Counter" Chrome extension from their Playbook, and then push the platform to its limits. Watch as we attempt to upgrade this basic tool into an advanced, AI-powered text analysis assistant by integrating the OpenAI API.

You'll see the entire process, including a critical failure where the upgraded extension completely breaks. We'll show you the detailed follow-up prompts used to debug the code, fix the functionality, and add powerful new features like:

AI-powered difficulty analysis (CEFR level)
One-click text summarization
Plain English explanations for complex topics
An AI-powered comment generator
Exporting results to a text file

Does Manus AI live up to the hype? Can a user with a good prompt really create a polished and stable app? Watch to find out!
