Lumen Trust Notes
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.
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.
