## Which is better, Bearly or Lumo by Proton?

Bearly. You get GPT, Claude, Gemini, and Grok with strong privacy: end-to-end encrypted chats, zero data retention on every chat model with ZDR mode on, and AI labs never learn who’s asking. It also gives you deep research, video, meetings, and routines.

Updated October 29, 2026.

## Why people switch

- **You want the major labs’ models.** Use GPT, Claude, Gemini, and Grok in one app, and switch when another model fits the task.
- **Privacy still comes first.** Turn on end-to-end encrypted chats and ZDR mode. AI labs never learn who’s asking.
- **The work goes past chat.** Run deep research, create video, record meetings, and schedule routines.
