TraceScholar AI

An intelligent research assistant using Retrieval-Augmented Generation (RAG)

A full-stack AI research platform supporting web search, document uploads, automated summarization and contextual question-answering.

  • Implemented document chunking, SQLite FTS5 retrieval, optional semantic embeddings and Reciprocal Rank Fusion (RRF) to generate source-grounded responses with citations.
  • Built an interactive React frontend and FastAPI backend with SQLite-based session management, research history and configurable OpenAI/Groq integration.
  • Developed a reproducible TF-IDF retrieval benchmark to assess document relevance, retrieval quality and ranking effectiveness using standard evaluation metrics.

Pramaan AI: Multimodal evidence pipeline. PDF upload, then Text and Tables & charts, then OpenAI embeddings · NumPy store, then Cosine-similarity retrieval, then Answer with page citations.

Pramaan AI

Evidence-grounded multimodal RAG for intelligent PDF understanding

A multimodal PDF question-answering system that processes text, tables, charts and visual information to generate evidence-grounded responses.

  • Implemented PDF text extraction, visual descriptions, OpenAI embeddings and NumPy-based vector storage with cosine similarity to retrieve relevant document evidence.
  • Built three answering modes (Text-only, Caption-Enhanced and Multimodal) with page-level citations, evidence identifiers and transparent RAG traces.
  • Developed a FastAPI backend with a browser-based interface, automated tests and a comparative evaluation of visual-aware PDF understanding.
