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.
Wispr Flow
Wispr Flow processes speech in the cloud rather than fully on-device, so data sovereignty is limited unless Privacy Mode is on and cloud sync is disabled. Enterprise customers get stronger guarantees (SOC 2 Type II, ISO 27001, enforced Privacy Mode, SSO). The free tier and broad device support improve access, but unlimited dictation requires a paid plan. Suitable for everyday writing and coding workflows; treat sensitive dictation like any cloud voice service and enable Privacy Mode for confidential content.
