Last year, privacy-focused productivity app company Proton released its public AI chatbot Lumo. On Tuesday, the chatbot was upgraded.
Lumo 2.0 brings a variety of new features to chatbots, including image recognition and image generation capabilities. Users can now upload photos to Lumo and use the chatbot to analyze or edit them. Like other LLMs, Lumo can also generate images based on user prompts.
2.0 also expands Lumo’s project capabilities. This widget allows users to upload documents and work through Proton’s other products such as email and cloud storage. Projects come with user-controlled persistent memory. This is a feature that allows Lumo to recall a user’s preferences across different conversation sessions.
Additionally, the company says that Lumo’s updates make it significantly more powerful than previous versions. Version 2.0 responds up to 76% faster to most queries than previous versions, the company says. Chatbots also feature new “thinking modes” to handle more complex problems and questions.
“Lumo 2.0 has been redesigned from the ground up, giving it powerful new capabilities with the introduction of Think Mode,” said Andyyen, founder and CEO of Proton. “Lumo 2.0 shows that users no longer have to choose between powerful AI capabilities and meaningful privacy protections.”
The public version of Lumo seems to be about on par with other major chatbots in terms of usefulness. It’s formatted similarly to Gemini and ChatGPT, and answers questions with roughly the same level of detail and context.
Still, Proton distinguishes Lumo from other chatbot providers when it comes to privacy protection. It uses what is called a zero-access encryption architecture, which encrypts user data in transit and at rest, and only allows access to the user. The company also claims that no server-side logs of sessions are kept, so no one at Proton can see the content of the conversations. Proton also promises not to use customer data for AI training or share it with third parties.
Lumo 2.0 is available immediately. In addition to the free public version, Proton offers paid tiers (Plus and Professional) that provide significantly more access and resources to these users.
