ChatGPT gates “confidentiality” behind expensive enterprise plans, and yet still has access to your business data, which can be given to authorities if requested.

Introducing our Business plan for Lumo, where everything is encrypted by default, and not even Proton can see chats.

Just came back from a trip abroad. Used @asklumo.proton.me before and numerous times during the trip to get ideas of things to see or do, historical background, etc. Very impressed. Was truly a travel assistant along our journey.

I've been using @asklumo.proton.me as my coding buddy for a few weeks, probably the best AI agent out there right now. Opensource, private and the coolest pet.

Act quickly; you have until November 3, 2025, to let Microsoft know that you don't want your LinkedIn data used for AI training.

You're opted in by default... Head to Account - Settings & Privacy > Data privacy > Data for Generative AI Improvement & toggle the switch off.

We are witnessing pivotal moment in AI.

You purr-obably know the answer.
