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.
Grammarly
Text is sent to Grammarly's cloud for analysis; enterprise plans add stronger admin and data controls, but standard use is not local-first (Privacy Low). Free tier plus accessible Premium pricing support Medium parity. Purpose is High—clear productivity value without dark-pattern lock-in for basic writing help. Provenance Low due to closed models. Fine for everyday writing; disable or avoid on highly confidential documents unless enterprise terms and settings meet your bar.
