Proton has released Lumo 1.3, introducing a new feature called Projects that changes how users manage long-term work inside its privacy-focused AI assistant. The update is for users who rely on AI for ongoing tasks such as reports, planning, research, and recurring workflows, without sacrificing data privacy.
Unlike traditional AI chats that reset context with every session, Projects allow Lumo to retain structured information over time while keeping everything encrypted and private.
What Are Projects in Lumo AI?
Projects are dedicated, encrypted workspaces inside Lumo that let users group:
- Related AI conversations
- Uploaded files and documents
- Custom instructions and preferences
Each Project acts as a persistent context. Instead of repeatedly explaining goals or background details, Lumo remembers the full scope of the task and continues from where the user left off.
This approach is especially useful for work that spans days or weeks, where continuity and accuracy matter more than one-off answers.
Why Proton Introduced Projects
One of the biggest limitations of most AI assistants is context loss. Even advanced tools often forget earlier discussions, forcing users to repeat instructions or reupload files.
Proton designed Projects to solve this problem while staying aligned with its privacy-first philosophy. The goal is to make Lumo feel like a long-term assistant that understands your work without collecting or storing data in a way that compromises security.
How Projects Improve Daily Workflows
Projects support structured, ongoing work rather than casual chat. Once you create a Project, Lumo automatically applies its stored context to every conversation in that space.
Key workflow benefits include:
- No repeated explanations: Lumo remembers instructions, tone preferences, and focus areas
- Better continuity: Conversations stay aligned across sessions and devices
- Clear organization: Each task has its own encrypted workspace
This makes Projects practical for activities like business planning, academic work, financial tracking, content drafting, or technical documentation.
Integration With Proton Drive
Projects integrate directly with Proton Drive, allowing users to link folders and documents to a Project. This means Lumo can reference relevant files when summarizing content, analyzing documents, or answering follow-up questions.
All linked files remain end-to-end encrypted and accessible only to the user. Lumo does not create server-side logs and never exposes data for AI training or third-party access.
Privacy and Security: What Users Should Know
Proton emphasizes that Projects do not change Lumo’s underlying privacy model. All Project data is protected using zero-access encryption, which ensures:
- Proton cannot read user conversations or files
- Chats are not logged on Proton’s servers
- User data is never used to train AI models
This design keeps Projects compliant with strict privacy standards such as GDPR and HIPAA, making them suitable for sensitive personal or professional work .
Availability and Plan Limitations
Projects are available to all Lumo users starting with version 1.3, but there are limits depending on the plan:
- Free users: Can create one Project
- Lumo Plus: Unlocks unlimited Projects, faster responses, advanced models, and unlimited chats
- Lumo Professional: Adds team-oriented features for businesses while maintaining the same privacy guarantees

This tiered approach allows casual users to try Projects while giving power users room to scale.
Lumo Projects vs Other AI Assistants
Many AI platforms are adding workspace-style features, but Proton’s implementation stands out because of its strict data protections. Unlike services that store or analyze chat history, Lumo Projects prevent even Proton from accessing the content.
For users who want AI assistance without exposing work data, this creates a meaningful distinction in a market increasingly dominated by data-hungry tools.
