Lumen Trust Notes
Otter.ai
Meeting audio and transcripts are processed and stored on Otter.ai cloud servers; no on-premise option exists for standard plans, which is a key consideration for legally sensitive discussions. The generous free tier and accessible pricing reflect genuine parity, and the core use case — reducing note-taking burden — is straightforward and valuable. Recommended for team meetings and interviews, but avoid using it for legally privileged or regulated conversations without reviewing Otter's data processing agreement.
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.
