Proton has released Lumo 2.0, its privacy-first AI chatbot. It now offers image generation, open-source models, and strict privacy controls, aiming to rival ChatGPT.
Proton has released Lumo 2.0, its latest version of the privacy-centric AI chatbot, featuring new capabilities like image generation and open-source models. The company emphasizes that Lumo 2.0 is designed to prioritize user privacy, setting it apart from competitors like ChatGPT.
Lumo 2.0 is accessible via web, Android, and iOS, and can be used for free without a Proton account. The paid Pro tier, costing $12.99 per month, offers additional features such as full chat history and advanced AI models. Proton highlights that Lumo 2.0 does not use user chats to train its models, with an option to keep chats private or delete them.
Key privacy features include zero-access encryption, meaning Proton staff and law enforcement cannot access chat content, and the chatbot runs on open-source AI models, enhancing transparency. Unlike ChatGPT, which uses user data for training, Proton states it does not review chats for training purposes. The company operates out of Europe, benefiting from stricter data protection laws.
Implications of Proton’s Privacy-First AI Approach
This development matters because it introduces an alternative AI service that prioritizes user privacy and transparency, addressing common concerns about data security and surveillance associated with mainstream AI platforms like ChatGPT and Google Gemini. Proton’s approach could influence industry standards for privacy in AI, especially among privacy-conscious users and organizations.

Proton’s Privacy Focus and Market Position
Proton, known for its privacy-oriented email, VPN, and cloud storage services, launched Lumo in August 2025. The company’s emphasis on privacy has been a core part of its brand, and the release of Lumo 2.0 reflects its ongoing commitment to providing AI tools that do not compromise user data. Previous versions of Lumo offered basic AI capabilities, but the new update significantly expands its features, including image generation and open-source models.
This move comes amid increasing scrutiny of data privacy practices by major AI providers like OpenAI and Google, who retain user data for model training. Proton’s transparent policies and European operations position it as a privacy advocate in the AI space.
“Lumo 2.0 is built with privacy at its core, ensuring no user data is used for training and that chats are protected with zero-access encryption.”
— Proton spokesperson
Remaining Questions About Lumo 2.0’s Capabilities
It is not yet clear how Lumo 2.0’s performance compares long-term to more established AI chatbots like ChatGPT in real-world scenarios. The quality of image generation and reasoning capabilities are promising, but user experience and scalability are still being evaluated. Additionally, Proton’s privacy claims, while transparent, have not yet been independently verified through extensive testing.
Next Steps for Proton’s AI Strategy and User Adoption
Proton plans to expand Lumo’s features and gather user feedback to refine its AI. The company may also explore partnerships or integrations to increase its reach. Monitoring user adoption and independent security audits will be key to assessing whether Lumo 2.0 can challenge mainstream AI services on privacy and performance.
