Why Supabase for this

A RAG system that cannot cite its source is a liability. Every answer we ship points back to the page it came from, so a reader can verify in one click.

Supabase is strongest at production-grade auth and RLS without building them, on standard Postgres you can leave. For rag & knowledge retrieval that matters because the failure modes of this kind of system tend to cluster exactly there.

The honest trade-off: opinionated in ways that occasionally fight a complex custom auth model. We say that up front because a stack chosen for fashion rather than fit becomes someone's migration project two years later. Integration comes before intelligence. A model that cannot reach your systems of record is a demo with good manners.

You own the code, the models where they are open-weight, and the documentation to run it without us.

We are not a reseller for Supabase and hold no commission on this choice. Where a different option fits your workload better, the recommendation will say so. That is the entire value of asking us.

What is included

  • Ingestion pipeline for your real document formats
  • Chunking and embedding strategy tuned to your corpus
  • Hybrid keyword plus vector retrieval with reranking
  • Citations on every answer, traceable to the source page
  • Permission-aware retrieval that respects existing access rules
  • Retrieval quality benchmarked against a labelled question set

Questions

RAG or fine-tuning?

RAG for knowledge that changes and must be cited; fine-tuning for style, format and task behaviour. Most production systems use RAG for the facts and light fine-tuning or few-shot prompting for the form.

How accurate will it be?

We build a labelled question set from your domain and report retrieval precision and answer accuracy against it. That number is the deliverable. We do not ship a system whose quality nobody has measured.

Can it respect our existing permissions?

Yes. Retrieval is filtered by the user's actual entitlements, so the assistant can never surface a document the user could not already open.

Alternatives for rag & knowledge retrieval

Same capability, different stack. Each page states its own trade-off.
