Key Features and Privacy Measures

Lumo boasts several privacy-enhancing features that set it apart from competitors:

  1. End-to-end encryption: All chats are encrypted and can only be decrypted on the user's device 2.
  2. Zero-log policy: Proton claims that no logs of conversations are kept on their servers 5.
  3. Ghost mode: Allows for disappearing chats that vanish upon closing the window 1.
  4. Web search disabled by default: Users must manually enable web access, which then utilizes privacy-friendly search engines 3.

Technical Infrastructure and Transparency

Lumo is built on open-source language models and operates from Proton's European data centers, subject to GDPR regulations 1. The AI assistant uses multiple models, including Mistral's Nemo, Mistral Small 3, Nvidia's OpenHands 32B, and the Allen Institute for AI's OLMO 2 32B model 3.

  2. Text generation and analysis
  3. File upload and analysis
  4. Integration with Proton Drive for secure document access 4

Availability and Pricing

Lumo is accessible via web browsers and mobile apps for Android and iOS. The service is offered in three tiers:

  1. Free: Limited queries and features
  2. Proton account holders: Additional features like encrypted chat history
  3. Lumo Plus: $12.99/month or $9.99/month (annual plan) for unlimited chats and extended features 4

Proton's entry into the AI assistant market with a privacy-first approach challenges the data collection practices of major tech companies. Andy Yen, Proton's CEO, stated, "Big Tech is using AI to supercharge the collection of sensitive user data to accelerate the world's transition to surveillance capitalism" 2.

While Proton's claims of enhanced privacy are compelling, users will need to trust the company's commitment to these principles. Proton's track record of transparency, including annual audits and published transparency reports, may help build this trust 2.
