  1. i would like to search a calendar for all non empty instances so that i can more easily edit events.

    in my specialised calendars like 'cashflow' 'garden'. I want a search option that returns 'all non empty non recurring events and the current instance of all recurring events, so that I can review the whole recurring structure more effectively.

  3. Proposal to Improve Lumo Naming and Presentation

    My name is Liese, and I am a researcher and engineer who currently uses Proton Business Suite + Lumo Business as an individual user. While using the service I noticed several points of confusion that I would like to bring to your attention and suggest improvements for.

    1. Inconsistent Naming Across Plans
      Lumo Plus – marketed as the premium plan for individual users.
      Lumo Professional – presented as a corporate‑oriented plan.
      Lumo for Business – essentially the same corporate plan but with a different name.
      Having three different names for what is fundamentally the same set of capabilities makes it hard for users to determine which plan best fits…

  6. Lumo vocabulary(s)

    For Lumo. You can add different categories for what it can do and or search for.

    • Comprehensive = Everything

    • Basic = Just basic Information+ sources. Perfect for those who need a quick lookup of information.

    • Custom = You define what lumo will do and or search for.

    • Take a chance = Gather random information based on what you are searching for. Some of it may not be relevant though.

  7. Shared calendars to be able to be set as default for both members of a duo subscription

    Shared calendars to be able to be set as default for both members of a duo subscription.

    I would like to be able to share a calendar with my duo member, and have this shared calendar a default for both. This would allow the color-coding system to be visible by both members of the duo subscription. This function is not available for the person who didn’t create the shared calendar

  8. Add a mid-price tier to Lumo

    Currently I can only get two flavours of Lumo: I can either use the free version and be (very) limited in using it, or pay the full price for all features. I'm not interested in using the most advanced llm and do not want to use it every day, so I'm not willing to pay €10 a month. At the same time, I'm willing to pay more then I pay now.

  9. Add support for multi-event calendar files

    My local utility provider publishes .ICS files with events like garbage containers being emptied:
    https://portal-api.kredslob.dk/api/calendar/icsfeed/07513454__29_______/18340

    I would like to import that into the Proton Calendar, but I am getting a message that multi-event ICS files are not supported. Would you be able to implement this feature?

  10. Setting for switching between 'enter to ask' and clicking to ask.

    Japanese (and perhaps other languages) requires the enter button to convert text into characters, which ends up asking Lumo before the sentence is fully written. This is frustrating as theres no other way to ask Lumo without typing the sentence somewhere else first, then copying. A feature to turn off 'enter to ask' would be appreciated.

  12. starting over from the beginning is annoying

    It's very annoying to have to scroll to pick up where I left off in a long chat. Please revert to the way things were before or add a setting for those who want to start the chat from the beginning.

  13. Hierarchical Multi-Task Constraint Optimization Engine

    I am writing to propose a mission-critical feature to address severe hallucination and performance degradation when processing complex, multi-project prompts with nested constraints.

    Problem Statement

    Our system currently exhibits fundamental breakdowns when handling prompts containing multiple distinct projects with interdependent constraints and domain-specific requirements:

    1. Critical Performance Drop: Benchmarks show accuracy falling below 10% compared to single-task prompts. When processing 32+ nested hierarchical tasks (e.g., "Project Z's Project B's Project D"), performance degrades to GPT-3 equivalence levels.

    2. Constraint Isolation Failure: The system cannot reconcile project-specific constraints with global constraints simultaneously. Complex nesting ("Project A's Project B's Project 9") causes complete context…

  14. Great Potential the ability to use both Scribe & Lumo together, dream come true!

    I started with this in Scribe then copy & paste to Lumo Web Search & got the results further from Lumo.

    I’m happy to dive into the world of AI‑powered license‑plate readers (LPRs) and give you a clear picture of what’s possible, where the technology shines, and what you should keep in mind before using—or even just exploring—such tools.

    How modern AI‑based LPRs work
    Image capture – A camera (often a dash cam, security cam, or a handheld device) records video or still frames of vehicles. Many systems use infrared illumination to see plates in low‑light or nighttime conditions.
    Pre‑processing…

  16. Theme

    I understand that this isn’t a priority right now, but in the long term it would be great to let Lumo have the same themes that are offered in the other Proton products (Mail, Drive..). (Lumo with Ebony would be beautiful 😍​)

  17. Custom shortcut/alias/abbreviation for a frequently used queries/prompts

    It happens that your Lumo question is long and used repeatedly while minor part of the question is variable. For example:
    Translate "string here" to spanish.

    Instead of needing to always write this sentence, i would like to setup custom shortcut, for example:
    t2sp paste here the phrase i would like to translate to spanish

    There would have to be some page, where i can manage all shortcuts (search/filter, sort). And it should not require learning/remembering any complicated syntax. Intuitive, layman friendly.

  18. Remember to Show or Hide a Calendar Per Calendar View

    Remember to separately hide or show a calendar per view type (e.g., days, weeks, months, etc.). For example, a daily tasks calendar is hidden by the user from the month and week views (because its events take too much space) but shows the daily tasks events on the day view automatically.

  19. Lumo system prompt

    When I ask Lumo for help, I have to always give instructions how it should respond, otherwise it may generate an undesired huge response for rather simple questions. Having an ability to predefine a system prompt to influence this behaviour is in my opinion a required feature. This feature could be also expanded to have several system prompts to choose from at the beginning of a conversation.

  20. Calendar, sélectionner / désélectionner tous ses calendriers d'un coup

    Bonjour,
    Dans le calendar, ça serait pas mal de pouvoir sélectionner / désélectionner tous ses calendriers d'un coup
    d'avoir une liste de ses évènements et que le "aujourd'hui" soit plus visible sur un affichage mois ou semaine.
    merci
