Proton has launched a new tool called Lumo, offering a privacy-first AI assistant that does not log user conversations and doesn't use their prompts for training.
Proton is a Swiss company behind proven privacy and security tools and services, including Proton Mail, Proton VPN, and Proton Drive. In June 2024, it transitioned to a non-profit structure, putting user privacy over profits.
The introduction of Lumo aligns with this mission, as Proton claims this AI tool is designed to provide help without tracking users, retaining or sharing their data, and hiding risky functions in closed-source code.
Instead, Lumo is based on open-source large language models (LLMs) and utilizes Proton's open-source encryption scheme. Proton also released the tool's complete source code, so it's fully transparent to the community.
Lumo's default setting is not to search online, delete all chats upon closing, and not store conversations on the server-side.
"Other AI companies keep a record of all your conversations on their servers, leaving this information vulnerable to data leaks or exploitation for profit," reads the announcement.
"Lumo doesn't keep any logs of your conversations server side, and any chats you save can only be decrypted on your device."
Lumo's interface resembles those of mainstream LLM services, while the tool supports file uploads with full encryption support.
