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.
Google Gemini
Gemini runs fully in Google's cloud with no local or self-hosted option for the consumer and Workspace products, so data sovereignty is Low. Google offers a genuinely usable free tier and broad accessibility, supporting High parity, while the product's clear productivity mission inside Workspace earns High purpose. Closed models and limited training-data transparency keep Provenance Low. Strong for Google-centric workflows; treat sensitive data under your organisation's Google Workspace and AI data-processing settings.
