Can RAG work with PDFs?

Yes. PDFs can be processed into searchable content, although scanned documents may require OCR and document structure can affect extraction quality.

Does RAG eliminate AI hallucinations?

No. RAG can ground responses in retrieved information, but retrieval errors, incomplete data and model behavior can still produce incorrect responses. Evaluation and guardrails remain important.

RAG applications retrieve relevant information from a controlled knowledge source and provide that context to a language model. They are useful for company knowledge assistants, document search and information workflows.

Enterprise RAG ApplicationRAG Development

RAG can connect an AI interface to controlled company information without requiring every document to be encoded into model parameters.

Key Takeaways at a Glance:

RAG combines retrieval with language generation.
Document quality and chunking affect retrieval quality.
Access control is important when multiple users have different document permissions.

Use Cases

Businesses often want AI assistants that can answer questions using internal documents, policies, product information or operational knowledge.

Retrieval-Augmented Generation provides an architecture for retrieving relevant information and passing it to a language model as context.

The quality of a RAG application depends on ingestion, retrieval, access control, evaluation and the quality of the underlying knowledge.

RAG Architecture

1. Ingestion

Business information is collected, parsed, cleaned and prepared for retrieval.

Documents

OCR

Parsing

2. Retrieval

Relevant information is identified for each user question.

Embeddings

Vector search

Metadata filtering

3. Generation

Retrieved context is passed to a language model to generate the final response.

LLM

Context

Response validation

RAG Development Checklist

1. Data Sources:Identify the documents, databases and knowledge sources that must be searchable.
2. Permissions:Define which users can retrieve which information.
3. Retrieval Quality:Test whether relevant information is retrieved consistently.
4. Evaluation:Create representative questions and expected answers for testing.
