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.
Fireflies.ai
Meeting audio and transcripts are processed and stored in Fireflies' cloud (Privacy Low). A usable free tier supports High parity, and the core mission—reducing note-taking burden—earns High purpose. Provenance Low for closed AI pipelines. Obtain participant consent where required and avoid privileged or regulated conversations without reviewing Fireflies' DPA and retention settings.
