Lumen Trust Notes
Claude
Claude is cloud-only with processing on Anthropic infrastructure; there is no self-hosted option, keeping privacy at Low. Anthropic's Constitutional AI framework and published safety research demonstrate a genuine ethical mission beyond commercial interest, earning a High Purpose score. A strong choice for teams needing thoughtful long-form analysis, but treat it like any managed cloud service with regard to sensitive data.
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.
