Buyer guide: cloud RAG alternative

PrivateDocs AI vs. Cloud RAG Platforms

Hosted RAG platforms (Glean, AWS Bedrock Knowledge Bases, Google Vertex AI Search) deliver great retrieval-as-a-service — but every query, indexed document, and embedding still lives in someone else's cloud. PrivateDocs AI moves the entire RAG pipeline — ingestion, embeddings, vector search, and inference — onto hardware you already own.

FAQ

Frequently asked questions

Why not just use AWS Bedrock Knowledge Bases or Vertex AI Search?

Both are excellent managed RAG services, but both index your documents in their cloud and route every query through hosted embedding and LLM endpoints. That requires a DPA, subprocessor review, and ongoing cloud egress of your content. If your use case tolerates that, they're great. If it doesn't, PrivateDocs AI gives you a comparable retrieval experience with zero egress.

What about Glean as an enterprise search alternative?

Glean indexes your SaaS apps (Google Drive, Slack, etc.) into a hosted index and uses cloud LLMs for answers. It's powerful for cross-SaaS search. For confidential local documents covered by NDAs or regulatory restrictions, PrivateDocs AI keeps the index and inference on the user's machine — no SaaS connector, no hosted index.

Does PrivateDocs AI replace cloud RAG entirely?

Not always. Many teams run both: cloud RAG for non-sensitive cross-SaaS discovery, PrivateDocs AI for confidential local documents. The architectures are complementary — but for the sensitive subset of your workflow, PrivateDocs AI is the only option that keeps content fully on-device.
