I built this because I needed it.

I am a software engineering student, just like many of you. And honestly? I was frustrated.

I wanted to build the absolute best tool for studying—something that I would actually use every single day. I looked at the current tools, and they felt incomplete. They were either just for writing, just for flashcards, or just for chatting.

I wanted more.

1. Visual Learning is Non-Negotiable

I learn by seeing, not just reading. Text isn't enough. That is why I integrated Manim and Mermaid directly into the app. When I'm studying algorithms or calculus, I need to see the math move. I need to see the diagram evolve. Foldex doesn't just give you text; it finds the YouTube videos and generates the visualizations you need to actually understand the concept.

2. An AI That Actually Helps (and Grades)

I didn't want a generic chatbot. I wanted a study buddy that works side-by-side with me on a Canvas. I wanted to be able to tag a PDF and chat with it, seeing exactly where the information came from—inline citations, just like NotebookLM.

But more importantly, I wanted confidence. When I use flashcards, I don't want to just flip them. I want the AI to grade my answer. I want it to tell me, "You missed this key keyword," or "Here is how you can improve." I want to walk into my exams knowing I can answer confidently because my AI tutor already grilled me on it.

3. Order from Chaos

The "Folder" concept wasn't an accident. I could have let people create loose notes and flashcards, but that leads to chaos. That isn't me.

I believe you must be organized to learn. A messy workspace leads to a messy mind. Foldex forces that structure so you never lose track of your progress.

4. A Community of Knowledge

Finally, studying shouldn't be lonely. I wanted to create a space where students don't just consume, but share. A place where you can clone a folder from a top student and help each other succeed.

This is the tool I wish I had in my freshman year. I hope it helps you as much as it helps me.
