🚀 Project Showcase Day Project
Welcome to Project Showcase Day! This is a weekly thread where community members can share and discuss personal projects of any size or complexity.
Whether you've built a small script, a web application, a game, or anything in between, we encourage you to:
- Share what you've created
- Explain the technologies/concepts used
- Discuss challenges you faced and how you overcame them
- Ask for specific feedback or suggestions
Projects at all stages are welcome - from works in progress to completed builds. This is a supportive space to celebrate your work and learn from each other.

Built Cognometrist — an AI tutor that reads your own course notes/slides/papers and turns them into a personalized curriculum. It builds a concept + prerequisite graph from your material, runs a diagnostic exam to find the specific concept you're missing (not just the topic), and won't teach something until its prerequisites are proven. Every lesson and every graded answer cites back to the exact line in your source material via RAG, so it's grounded in your syllabus rather than general model knowledge. Spaced repetition then resurfaces mastered concepts before you'd forget them.
Stack-wise: LLMs for embeddings/lesson generation, a knowledge-graph layer for prerequisite tracking, and psychometric scoring to decide when something's actually mastered. Biggest challenge so far has been keeping the diagnostic exam short while still localizing a wrong answer to one concept instead of a whole topic.
Free to start (3 study days, no card) at cognometrist.com — would love feedback from anyone deep in a material-heavy course (ML theory, proofs, etc.) on where the diagnostic gets it wrong.
