NeuralNest began as a personal project , I wanted to see if an AI tutor could verify a student's understanding instead of just dumping explanations at them. Surfboard Ventures picked it up, looking for a ready-to-use AI study tool rather than starting from zero.
The hardest problem was making the tutor genuinely teach, not just answer. I built a LangGraph workflow where a grading node checks comprehension after every explanation, classifies the response as understood, confused, partial, or a doubt, and routes the student accordingly, a simpler analogy, a deeper breakdown, or a doubt-handling node, without losing state. Getting these classifications reliable took real prompt tuning.
Retrieval was another challenge. Students upload PDFs, DOCX files, and images (OCR'd via GPT-4o Vision), and the tutor pulls context from the right scope, one session, selected materials, or the entire knowledge base. I used a multi-namespace Pinecone setup with Cohere embeddings to keep data isolated while enabling flexible retrieval.
For exam prep, a pipeline parses past-year papers, ranks topics by frequency, and prioritizes high-yield topics in the study plan, recalibrating if quiz scores slip.
The result: a full agentic study platform, topic extraction, a visual roadmap, adaptive quizzes, mastery scoring, and full tracing, that Surfboard Ventures was happy to take over.
