First place, Noesis Hackathon, Vedam School of Technology (8 hours, about 50 teams)

What it does

Upload lecture notes as PDF or text, then ask questions and get answers grounded only in that material, with citations to the file and chunk and a confidence badge. Or switch to study mode and generate five MCQs or three short-answer questions from the same chunks. Voice in and out through the Web Speech API.

Retrieval

Notespdf-parse, 500/50 chunksGemini embeddingsper chunkChromaDBuser + subject metadataQuestionembedded, top-kThreshold 0.30else "Not found in yournotes"Answercitations, confidence
Chunks of 500 characters with 50 overlap; a 0.30 similarity floor; refusal when nothing clears it.

Confidence is computed from the similarity scores of the chunks that survived the threshold, and forced to Low whenever the model answers “Not found in your notes”. That refusal path is the anti-hallucination layer: the system would rather say nothing than invent.

The hackathon, and who did what

Noesis, Vedam School of Technology, eight hours, about fifty teams. A rule change halfway through and a connectivity failure near submission. We were shortlisted to the top ten and then announced first. Team: Nimit Jain (landing page, frontend, Supabase auth), Ved Kumar Singh (the three API routes), and me (the dashboard, and the RAG design with Ved: ChromaDB, the chunking and overlap, the retrieval). The commits for the routes are Ved’s; the design of what they do was shared work.
