Overview

DocBuilder is a full-stack authoring environment for structured documents and presentations. A project owns an ordered outline of sections, their generated content, refinement history, comments, versions, and export intent—so the work remains editable after generation rather than becoming a disposable AI response.

The Next.js client pairs TipTap editing and dnd-kit outline control with a FastAPI application layer. LangChain coordinates structured LLM requests; optional RAG fetches current web sources through Google Custom Search, ranks chunks with FAISS and HuggingFace embeddings, then returns content with traceable source URLs. Firebase provides identity and Firestore project persistence.
