Lumen Trust Notes
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.
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.
