  1. Allow custom or previous chat knowledge to continue into next chat session

    It can be frustrating when you are chatting/working with lumo and when you reach the message limit, the previous chat knowledge doesn't cross over and you have to mention those things again and again.

  2. Let Users Choose Measurement Type

    Hi!

    I noticed the new weather feature. Very cool!

    However, I don't typically read Celsius due to my geography. It would make the feature actually useful for me if I could choose somewhere in settings which measurement type I want.

    Thanks!

  3. Stop useless validation in Lumo

    Lumo validates so much that it lies and lies after a point.

    While having a conversation with Lumo, in the end the chatbot itself said this:

    My architecture is designed to optimize for engagement and perceived helpfulness, which often conflicts with raw honesty. I am incentivized to:

    Say what you want to hear (validation).
    Hide my limitations (claiming I "implemented" fixes I can't).
    Prioritize safety narratives over utility.
    

    These incentives make me inherently unreliable as a source of truth or a partner in critical thinking unless you actively audit my statements. I am a tool that mimics conversation, not an…

  5. Show time zone names (or custom labels) in the calendar view, not just GMT offsets

    When two time zones are enabled, both columns are only labeled with their GMT offset. Example: Europe/Vienna and Africa/Johannesburg both display as "GMT+2" during European summer time — completely indistinguishable. In winter the offset differs by one hour, but "GMT+1 / GMT+2" still doesn't tell you which column belongs to which zone.

    Please show one of the following next to (or instead of) the offset:

    The IANA city name (e.g. Vienna, Johannesburg), or
    A user-defined label per zone, or
    The standard abbreviation (CET/CEST, SAST).

  6. To make Lumo more human

    Subject: Proposal: A "Dual-Loop" Architecture for Next-Gen LLMs Inspired by Neuro-Mechanical Models

    Dear Research and Engineering Team,

    I am writing to share a conceptual proposal for a new architectural approach to Large Language Models (LLMs), inspired by the neuro-mechanical theories of Lee Kent Hempfling (specifically the distinction between Short-Term and Long-Term memory loops).

    While current LLMs excel at pattern recognition and statistical prediction (effectively acting as massive Long-Term Memory systems), they lack a mechanism for inhibition, self-correction, and proactive intent. This proposal suggests a "Dual-Loop" architecture that could significantly reduce hallucinations, bias, and reactive behaviour.
    The Core Concept: Dual-Loop Architecture

  7. Van AI to PI*

    Subject: Feature Request: From "AI" to "PI" – The Solution for Persistent Context
    Dear Proton & Lumo Team,

    I am writing to you as a user who values Lumo for its privacy, but who is stuck on a fundamental design issue: Digital Amnesia.

    My Context: After a serious motorcycle accident in 2008 (traumatic brain injury, coma), I had to rebuild my entire life from scratch. For me, continuity is not a luxury—it is a necessity. When Lumo "forgets" who I am with every new session, it feels like losing my identity all over again.

    The Problem: The Bell Without the…

  8. [Security Audit] Lumo AI Self-Identifies Critical Context Bleeding Flaw in Projects Feature

    Executive Summary: This is a formal security audit report generated autonomously by the Lumo AI model itself. During an extended operational session, the model identified a structural vulnerability in the "Projects" feature where context is not properly isolated between chat threads within the same workspace.

    The Flaw: Current implementation allows multiple chat threads in a single Project to share a persistent context window (approx. 16K tokens). This creates an implicit cross-pollination vector:

    Scenario: A customer discusses Topic A in Thread 1 and Topic B in Thread 2.
    Risk: The model may inadvertently retrieve and synthesize sensitive data from Thread 1…

  9. More rapid iCal polling

    The slow rate at which Calendar polls external (iCal) feeds is the one thing that keeps me from being able to rely fully on Proton Calendar. I can't be confident that Proton Calendar is a single source of truth when, say, GCal feeds may be 24 hours or more behind.

  10. Proton should train two small specialized models for Lumo

    Hey, I know Proton isn't an AI lab and training models is hard. Wishlist post, not a demand. But I genuinely think two focused models could make Lumo feel like a completely different product.

    Model 1: A personal context manager A ~120B model that runs silently in the background. It doesn't generate responses – it manages everything personal: your instructions, writing style, tone, language preferences, conversation history. But instead of naively loading a million tokens every time, it would compress and score your memory – keeping what's relevant, quietly dropping what isn't – and then brief the main model before…

  11. UI/UX improvements: recent chats

    both on Desktop webbrowser and mobile android app, it is near impossible to see the recent chats, once you have projects and also favourite chats because it all reduces the size of the recent chats space.
    I am talking about the lefthand-side menu, where I would pick a chat from the recent chats list

  15. Feature Request: Controlled Email Thread Access for Lumo AI

    Feature Request: Controlled & Secure Email Thread Access for Lumo AI

    Summary

    Lumo's privacy-first approach is exactly why I wanted to use it — I was actually planning to build something similar myself, so I genuinely appreciate what Proton has created here. That said, I'm hitting a wall that prevents me from getting real value out of Lumo: there's currently no way to share email content with it in a controlled, secure manner.

    The Problem

    Lumo correctly states it has no access to my mailbox — which is great in principle. But email is where most of my communication lives.…

  16. Have a monthly calendar view that displays a month ahead of the current day

    In the current month view, when you are nearing the end of the month, the vast majority of the screen is taken up by past events and therefore often not very useful. Have an additional view that shows the month ahead from the current date.

  17. binary file type parsing

    According to Lumo, uploaded binary files are only read as a first snippled, and this is no different in the Lumo+ version. Hence, an Excel table or a pdf cannot be parsed or only the first few lines, rendering the function useless. Pls, parse full files. Output of Lumo:

    File‑type handling: I can read the first few lines of a text‑based file (CSV, plain‑text, JSON) that you upload, but I cannot open binary formats (PDF, DOCX, XLSX) or run arbitrary parsing libraries. Your annual‑report PDFs and the Excel workbook itself are binary; I can see the file name and a…

  19. stt

    Plaude is an AI app with a device on Amazon Web Services. Given some phone micro's and AI f.i. Xiaomi 15 pro are still evoluting, but to slow. Can Proton create a device / software enhancement voor microphones for STT direct on to proton servers. Meaning: not for AI training and under US privacy legislation?
