How it works

This is a RAG system: Retrieval-Augmented Generation. The AI looks things up before it answers.

1

Read

Your browser reads the PDF and splits it into short passages, remembering each passage's page.

2

Understand

Each passage becomes an embedding: a list of numbers that captures its meaning.

3

Search

For your question, a hybrid search finds the best passages by meaning and by keywords.

4

Answer

The AI answers using only those passages, and cites the page each fact came from.

Features

Built to give answers you can trust.

๐Ÿ“Œ

Page citations

Every fact has a page chip. Click it to see the exact passage the answer used.

๐Ÿ™…

No guessing

If the document doesn't say it, the chatbot says "I couldn't find that" instead of making something up.

๐Ÿ”Ž

Hybrid search

Combines meaning-based search with BM25 keyword search, merged with Reciprocal Rank Fusion.

๐Ÿ’ฌ

Follow-up questions

Remembers the conversation, so you can ask "and what about part-time staff?"

๐Ÿ”’

Private

The PDF is read in your browser and never saved. Close the tab and it's gone.
