NotebookLM first, custom RAG when needed

Content Analysis

Use NotebookLM by default. Build custom RAG only when you actually have a reason.

Context

For most teams NotebookLM is enough — fast, source-grounded, no setup. When data has to stay private, scale beyond NotebookLM's limits or integrate into other tools, we build a custom RAG pipeline on OpenAI/Anthropic plus Pinecone or Supabase Vector.

When NotebookLM is enough

Up to a few hundred sources, non-confidential data, one team, casual querying. NotebookLM gives you 80% of the value at 5% of the engineering effort. Don't over-build.

When to build custom RAG

Confidential or regulated data, integration into your own product, scale beyond NotebookLM's quotas, fine-grained access control, custom retrieval logic. We build on OpenAI/Anthropic + Pinecone or Supabase Vector + clear eval harness.

Checklist

  • Default to NotebookLM — graduate only with reason
  • Always plan eval harness before going custom
  • Decide access control upfront
  • Stay model-agnostic where possible
