Do we need a vector database?

Sometimes Postgres plus good metadata is enough at the start. We add specialised stores when volume and latency require it.

Will RAG stop hallucinations?

It reduces them. It does not make a model incapable of ignoring the retrieved text. We still constrain and evaluate.

Can you index our entire Google Drive?

We can ingest what you designate. ‘Entire Drive’ is how secrets leak. We start with a named corpus.

RAG Development

Retrieval-augmented generation is how a chatbot or assistant stays honest: it looks up, then it writes. AppsAura builds RAG when you have documents, tickets or product data that change, and you need answers that can show a source. If the corpus is ten pages, a static FAQ may be enough — we will say so.

Service overview

Chunking, embeddings, metadata filters and re-ranking are the job. Access control is the job people skip: a vector store that ignores roles will leak. We keep document ACLs in the filter, not as a hope. We measure recall on real questions, not a demo query the author wrote.

Problems we solve

One giant chunk size that loses tables and headings.
No ACL on retrieval — intern sees finance PDFs.
Stale indexes after a CMS publish.
Citations that point at the wrong paragraph.

What we build

Ingestion pipeline with versions and deletes
Metadata filters (role, product, language, date)
Hybrid search when keyword still wins
Citation UI that a human can check
Eval harness on a question set you own
Rebuild and incremental update paths

Benefits

Answers that can be audited.
A corpus that product and legal can reason about.

Use cases

Internal runbooks for operations software.
Help centre grounded chat.
Policy documents next to a Vistarx-style compliance workflow.
