Overview

End-to-end automation for document ingestion, indexing, and retrieval.

The AI agent monitors Google Drive for new documents, extracts text from PDFs, CSVs, and Google Docs, and creates context-preserving chunks. It stores vector embeddings in a secure Supabase vector store to enable fast semantic search. It provides an interactive OpenAI-powered chat interface that returns precise, document-based answers.

Why you should use AI Agent for RAG Document Processing & Chatbot

Before you implement this AI agent, you face manual, error-prone document handling and slow knowledge retrieval. After deployment, you gain automated ingestion, consistent extraction, fast semantic search, and accurate document-based answers.

Before
Manual document intake and format handling causes delays.
Text extraction is inconsistent across PDFs, CSVs, and Docs.
Finding relevant content requires manual searching and flipping between tools.
Context is lost during chunking, hurting answer accuracy.
Embeddings storage and retrieval are fragmented and slow.
After
Documents are ingested and processed automatically on upload.
Text extraction is consistent across formats with structured outputs.
Semantic search returns relevant results with preserved context.
Embeddings are stored securely in a scalable vector store.
Chat-based QA delivers precise, document-based answers quickly.
Process

How it works

A simple, 3-step flow anyone can use.

Step 01

Step 1: Detect and Ingest

The agent monitors Google Drive and triggers ingestion when new or updated documents appear.

Step 02

Step 2: Process and Chunk

Extracts text, splits into overlap-preserving chunks, and enhances content quality.

Step 03

Step 3: Store and Retrieve

Stores embeddings in Supabase and enables semantic search and chat QA against the stored documents.


Example

Example workflow

A realistic scenario showing time and outcomes.

A product team uploads 20 PDFs and 15 Google Docs to Google Drive. The AI agent ingests, extracts, chunks with context, and stores embeddings in Supabase. The team then asks, “What are the known issues for feature X?” and receives a concise, ranked list of relevant documents with summaries within minutes.

FAQ

FAQ

Practical, real-world questions about the AI agent.

RAG combines retrieval-augmented generation with a document store to provide accurate, source-backed answers. The agent ingests documents, creates embeddings, and retrieves relevant content to answer user queries with citations. It supports multiple document formats and preserves context for reliable results. This approach reduces your time spent locating and verifying information.

Yes. The agent ingests and processes PDFs, CSVs, and Google Docs (including Docs converted from PDFs or CSVs). It extracts text, preserves formatting where possible, and creates context-preserving chunks for accurate retrieval. Embeddings are generated from these chunks to enable fast semantic search.

Data is stored in a dedicated Supabase vector store, which is designed for secure, scalable vector embeddings. Access control can be configured at the project and document level. Embeddings are used solely for semantic search and QA; raw documents remain in the source storage (e.g., Google Drive) with access governed by your existing permissions.

This agent runs as part of your existing cloud setup (e.g., a hosted n8n workflow). It requires access to Google Drive, a Supabase project for embeddings, and OpenAI (plus Gemini) credentials. Processing limits such as chunk size and overlap can be tuned to balance performance and cost.

The chatbot queries the vector store for relevant chunks, synthesizes a response with citations, and presents an answer in natural language. It can provide summaries, key findings, and direct references to source documents. If confidence is low, it can suggest multiple candidate sources for user verification.

Yes. You can configure chunk size and overlap to optimize context preservation and search accuracy. Larger chunks provide more context but may increase latency; smaller chunks speed up search but can reduce context. The right balance depends on your document mix and query types.

This AI agent is versatile for knowledge-intensive domains such as research, legal, finance, IT, and customer support. It excels where teams need quick, accurate access to large document stores and where decisions rely on cited sources and traceable context.
