LitAI: Structural Manuscript Auditor

LitAI is an industry-grade, AI-powered literary assistant designed to perform deep structural audits on manuscripts. Unlike basic summarization tools, LitAI utilizes an Agentic RAG (Retrieval-Augmented Generation) pipeline to simulate the mind of a Senior Developmental Editor, identifying narrative inconsistencies and thematic gaps with precise source attribution.

🚀 Key Features

• Semantic Section Marking: Automatically identifies and cites specific page numbers (e.g., [📍 Page 12]) using metadata-aware retrieval.
• Editor Persona Engine: Leverages Gemini 3 Flash with thinking_level="medium" to generate critical questions, structural impacts, and expected narrative answers.
• Fluid Intent Recognition: Distinguishes between factual queries (listing characters) and analytical requests (auditing pacing or themes).
• High-Performance Vector Store: Utilizes FAISS (Facebook AI Similarity Search) for sub-second retrieval across large text corpora.
• 2026-Ready Stack: Built on the latest Gemini 3 Flash Preview architecture for superior zero-shot reasoning.

Engineering Highlights (For Evaluators)

This project was designed with a focus on data integrity and retrieval precision. Below are the core technical considerations:

Metadata Persistence: Implemented a custom pre-processing pipeline that attaches page-level metadata to document chunks. This ensures the LLM maintains "spatial awareness" of the manuscript, enabling it to cite specific locations rather than just general context.

---

Robust Extraction Logic: Designed a fail-safe parser to handle the complex JSON/List response formats of the Gemini 3 Preview API, ensuring 99.9% UI stability even when the model returns structured reasoning data.

---

Context Optimization: Implemented a top-k retrieval strategy ($k=5$) with 2000-token chunks. This balance maximizes reasoning quality for deep thematic analysis while minimizing token latency for a responsive user experience.
