Claude in Excel.
Your policies. Your audit trail.
Route Claude for Excel & PowerPoint through BrainstormRouter. Every cell formula and slide generation flows through your governance layer — budget limits, PII scanning, model routing, full observability.
Direct Excel → Claude skips governance.
No budget limits. No audit trail. No PII scanning. No central credential management. Via BrainstormRouter you get per-user budget enforcement, full request/response audit logs, PII scanning before relay, intelligent model routing, server-side key storage, and real-time dashboards.

Finance team: Sonnet for forecasts, Opus for quarterlies.

Guardian Intelligence predicts cost before execution and blocks requests exceeding monthly per-user budgets. Every request lands in the audit trail for compliance.
