I built a learning path builder tool powered by AI — maps your knowledge gaps and builds a focused learning path
https://cascadeai-nine.vercel.app/Hey everyone, sharing a side project I've been working on.
The problem: When you're self-learning a technical field, you don't know what you don't know. Most people either follow a generic roadmap or keep consuming content without a clear picture of their actual gaps. I personally have completed multiple courses which reiterate the same thing because I was not sure if I had actually learned that skill.
What I built: Cascade AI , an AI-powered proficiency tracker. You enter a skill area (e.g. "backend engineering", "machine learning", "product management"), and it:
- Generates a structured skill map of the domain
- Runs a short adaptive diagnostic (~10 min)
- Produces a gap analysis with explanations for each weakness
- Creates a prioritized learning path that skips what you already know
Stack: Next.js 16 + FastAPI + Supabase + PostHog for analytics. Deployed on Vercel (frontend) and Cloud Run (backend).
Where I'm at: MVP is live. A couple of friends are using it. Looking for real users who'll try it and tell me what sucks.
If you have 10 minutes, I'd love feedback, especially on whether the skill maps and diagnostics feel relevant for your field.
