Lumen Trust Notes
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.
Notion AI
Notion AI processes data on Notion's cloud infrastructure via third-party model providers (OpenAI, Anthropic); there is no self-hosted or local option. Its add-on pricing model is reasonable and its deep integration with existing workflows provides genuine productivity value without dark patterns. Ideal for teams already on Notion, but review Notion's sub-processor data agreements before storing sensitive client information.
