Proton’s Lumo (https://lumo.proton.me/) is a secure, European-hosted text chatbot with zero-access encryption, no data sharing or retention.

Document import and web search.

Seems to work on several “light” open models chosen according to the instruction (apparently Nemo and Small 3 from Mistral, OpenHands 32B from Nvidia, or OLMO 2 32B from the Allen Institute – source <a href="https://www.01net.com/actualites/lumo-le-chatbot-de-proton-qui-ne-veut-pas-fouiller-dans-vos-donnees.html”>01net).

Web, iOS, and Android.

Can be used free of charge without or with an account (encrypted history if account) with a limited number of daily requests.
