Lumen Trust Notes
Gamma
Gamma runs entirely on cloud infrastructure with no local processing option. The free tier is genuinely generous with AI credits and no hard feature wall, reflecting strong access parity across users. Recommended for teams and individuals creating presentations, proposals, or reports — avoid embedding confidential financial or client data in shared Gamma decks.
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.
