Everything you need to ship RAG, nothing you have to build yourself

Focus on your product. We handle the retrieval infrastructure underneath it.

Grounded, cited chat

Every answer streams in real time and links back to the exact source passages it was built from — not a paraphrase, the actual quote and page.

Isolated knowledge bases

Organize documents into knowledge bases per product, team, or customer, each with its own independent retrieval scope — nothing bleeds across boundaries.

Nexus is infrastructure, not just a dashboard

Everything you can do by hand, your product can do programmatically — poll ingestion status, list what's indexed, and build your own UI on top of the same data the dashboard reads.

Every dashboard action has a matching, scoped API key.
Invite teammates with org-level roles — owner, admin, member.
Tokens, requests, and cost tracked per organization, daily.

GET/v1/knowledge-bases/:id/documents

Trust is an architecture decision, not a marketing page

These are guarantees the system enforces, not claims we make.

Isolated by design

Every organization's data lives in its own row-level-secured slice of the database — enforced at the database layer, not just application code.

Scoped API keys, per-organization rate limits, and usage tracked to the token.

Citations you can verify

Every source cited in an answer is checked against the documents actually retrieved for that request. If a claim isn't backed by your documents, it isn't cited.

Failed or stuck processing shows up in your dashboard immediately — not in a support ticket.
