Lumen Trust Notes
Google Gemini
Gemini runs fully in Google's cloud with no local or self-hosted option for the consumer and Workspace products, so data sovereignty is Low. Google offers a genuinely usable free tier and broad accessibility, supporting High parity, while the product's clear productivity mission inside Workspace earns High purpose. Closed models and limited training-data transparency keep Provenance Low. Strong for Google-centric workflows; treat sensitive data under your organisation's Google Workspace and AI data-processing settings.
Microsoft 365 Copilot
Copilot processes prompts and organisational content in Microsoft's cloud; enterprise controls and compliance certifications exist, but there is no local-first option for standard M365 Copilot, keeping Privacy Low. Per-seat business pricing and licence prerequisites limit access parity for individuals and small teams. Purpose is High—it meaningfully accelerates real office workflows inside apps people already use. Closed models and opaque training details keep Provenance Low. Best for Microsoft-centric orgs with clear data-governance policies.
