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.
Fireflies.ai
Meeting audio and transcripts are processed and stored in Fireflies' cloud (Privacy Low). A usable free tier supports High parity, and the core mission—reducing note-taking burden—earns High purpose. Provenance Low for closed AI pipelines. Obtain participant consent where required and avoid privileged or regulated conversations without reviewing Fireflies' DPA and retention settings.
