Everything you need to build with Arcus.
Guides for the people who'll actually use them — from "I just want to ask my first question" to "I'm wiring Arcus into a CI pipeline." Written by the engineers who build the product, kept honest about what works today.

From SQL fragment to versioned, governed metric — usable across every thread.
Automate a brief
Three-step builder turns an ad-hoc question into a recurring brief or alert.

Connect BigQuery
Create a service account, scope it to a dataset, and connect BigQuery to Arcus.
Connect Postgres
Connect a Postgres database (or Supabase) to Arcus with a read-only role.
Ask your first question

Understanding the answer card
The three-layer answer format — narrative, chart, source/trace — and why every Arcus answer renders this way.
Define a metric
Add a custom metric to the semantic layer so the agent uses it consistently across questions.
