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.
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.
