AI Document Intelligence System
A FastAPI service that ingests PDFs, chunks them, runs LangChain pipelines for summarization, key-insight extraction, and translation.

The problem
Knowledge workers drown in PDFs — reports, contracts, papers. They need focused summaries and the ability to ask questions of the document, in their own language.
The approach
- PDF parsing with layout awareness (so tables and headings survive).
- Recursive chunking sized to the model’s context, with overlap to keep cross-paragraph references intact.
- Three composable LangChain chains:
summarize,extract_insights,translate(target_lang). - Single FastAPI surface so the same backend powers a web UI, a CLI, and an internal Slack bot.
Outcome
- Average 95% reduction in reading time for the target users.
- Translation pipeline supports any language the underlying model handles — particularly valuable for Urdu/Pashto documents that desktop tools mangle.
