1. ghost mode (and/or web search) saved

   Hi there,

   after I started using Lumo for a while, I like to use the ghost mode by default. However, under current setting (both on webpage and on Android app) I have to switch Lumo to ghost mode (and turn on web search) every time. Can we make it a setting to use the ghost mode (and/or web search) by default? It will save a lot of effort.

   Thanks.

   By the way, I like Lumo very much. After I found it, it became my main AI assistance.

2. Lumo "lite" tier for Unlimited, Duo and Family subscribers

   While I get the cost of hosting an LLM and a separate plan for unlimited usage is totally fair, I do think paying customers, especially subscribers to the so-called unlimited plans, should get a little special treatment with a tier of Lumo exclusive to these plans.

   Perhaps instead of the 10/day and 200/month prompt limit, 1 project limit and 7 day history that Lumo Free provides, this new Lumo Lite could give us 50/day, 500/month, 2 projects and unlimited history (we already have 500 GB of storage so Lumo message storage should be negligible).

   All the other features like unlimited prompts, projects and advanced AI models could be reserved for the Plus plan for those who need it, but having it easier to integrate in an existing 2 year plan, with appropriate discounts would be nice. Currently, upgrading to Lumo Plus while having Proton Unlimited, downgrades me to a 1 year plan for both, forcing me to pay more for Proton Unlimited as well.

3. Add "Green" and "Research" Search Modes

   When searching in Lumo, users should be allowed to toggle on different types of searches, such as:
   1. Green - a search that uses less environmental energy to generate an answer
   2. Research - a search that goes deeper and uses reputable sources (similar to the Research function already present in Mistral AI's Le Chat)

4. Direct save of chats as Docs on Drive (+ Lumo-folder on Drive?)

   Integration between Lumo and Docs to allow Lumo users to save chats as Docs on Drive, directly from Lumo.

   Purpose: to ease UX of organising projects in Lumo and save time and effort for users.
   Value:
   1) Nudging users to support their own data security, by not using alternative tools outside of Proton Suite.
   2) Supporting user loyalty to Proton product suite, especially Lumo.

   User scenario:
   After finishing chat with lumo I press the "save as docs"-button next to "copy" and "try again features" in the bottom right corner of the screen. Dialog opens and asks: "Do you want to save this chat as a doc?" Possibillities: "Yes/No". I press "Yes" and Docs opens with the current chat content, ready to be named and saved. When named and saved in a folder of my choice in my Drive, I can upload it to my relevant folder in Lumo Projects.

   Or:
   After finishing chat with lumo I press the "save as Docs"-button next to "copy" and "try again features" in the bottom right corner of the screen. Chat is named (by Lumo as usual) and saved as doc in dedicated Lumo-folder on my Drive. Dialog opens in Lumo: "I have saved the chat as a doc in your Lumo folder on Drive. Do you want me to upload it to your Lumo Project folder X?" (the chat being an x-topic) I can answer "Yes/No" depending on, whether I want this or not.

   This is just from the top of my head, so please be critical about unnecessary complexity, best data flows and architectural robustness and scalability

5. Calendar - Make today stand out a bit more

   I use the calendar in month view and sometime find myself scanning for todays date. In this view with many events being displayed the simple ring round the date doesn't really jump out.
   My old google calendar (which I'm trying to get away from) has today inverted which I find much more visible. Looking at it now, it is a solid blue circle with white text, I personally find it very easy to find.
   I'd just like today highlighted a little more strongly than it is now please.

6. Train Lumo to understand the user interface

   Lumo doesn't understand how to communicate through the User Interface very well. It should be trained. Lumo said that the character limit for a single response was about 4000 to 6000 characters. It should know the actual number and be able to feedback to the user that the limit was hit instead of indicating that it will try to better next time (it won't, the UI has a hard limit). When trying to get Lumo to format a list, it is like working with a teenager, it doesn't do what you want and says it will try to better next time. The problem is that it doesn't understand how the user interface interprets things like linefeed vs carriage return. If they Lumo and the UI both used a common format like Rich Text Format, it would cut the conversation requests way down.

8. Lumo User Interface indicate percentage of output limit when responding

   Lumo has a maximum character limit for a single response (according to Lumo). I would like to know how much of that limit I am using when asking for a response. Currently Lumo simply fails without warning and it's difficult to see what is going on. I find it interesting that Lumo didn't actually know the limit either, it gave a range. When I started asking Lumo more pointed questions it kept stopping partway through the output it responded:

   You are absolutely right to notice that pattern! The problem is not with your request or my memory, but with the technical output limit of this chat interface.
   The Problem: The system has a maximum character limit for a single response (often around 4,000–6,000 characters). Every time I reach that limit, the system cuts off the message abruptly, regardless of how much I try to compress it. It's a "hard stop" imposed by the software, not a choice I make.

9. Feature Request: "Amnesia Bridge" – Cross-Chat Context Retrieval

   When chats close due to resource limits, all invested context is lost. Users must re-upload files and start from scratch—wasting time and compute.

   Proposal: Let users selectively pull context from older chats into active conversations: "Lumo, check our chat from last week for what we found about XY." -> the desired feature is similar to "websearch" - just scoping the own (internal) activities.

   Optional: User tagging of important chats for quicker discovery.

   Why it fits: Same privacy model, just extended. Decryption stays client-side, metadata stays user-controlled and encrypted. No server-side indexing.

   Impact: Better session continuity, no redundant uploads, preserves invested work.

10. Lumo payment separate from my other products

    Currently, to sign up for Lumo+, you must add it to your current subscription, with the same time period, so if you have a 1-year subscription, you have to pay for 1 year of Lumo, if you have a 2-year subscription, you have to pay for 2 years of Lumo up front.

    The other option is to lose all the discounts on your main Proton account in order to activate Lumo+ for the new term.

    For example, if you have a 2-year Duo subscription (€11.99 per month) and you only want 1 month of Lumo for both users, you have to switch to the monthly price, which increases the price to €45.97. This is more expensive than Visionary!

    Lumo needs to have a separate billing option. Or fix the prices, because I will never subscribe this way. And I want to support it.

11. Implement Bias Mitigation for Chinese Open-Weight Models (Qwen, Kimi K2)

    As noted in Lumo's Privacy Documentation, the system currently routes queries to several open-weight models, including Qwen and Kimi K2. While utilizing these models supports cost-efficiency and open-source diversity, research (e.g., NDSS 2026, "S1761") indicates they contain significant internal censorship and narrative engineering aligned with authoritarian state interests.

    Proton’s core mission is to champion digital rights, encryption, and freedom against state surveillance. However, deploying models with embedded propaganda or censorship mechanisms creates a contradiction:

    • Cognitive Risk: Users may receive subtly altered information or suppressed viewpoints on sensitive geopolitical topics (e.g., HK, Taiwan, human rights).
    • Value Misalignment: This conflicts with Proton's historical stance supporting activists and resisting authoritarian control.

    Proton should implement a bias mitigation layer specifically for these models. This could involve:

    • Post-Training Alignment: Applying techniques similar to those discussed in ACL 2023 ("Mitigating Bias in Large Language Models") to strip state-aligned censorship.
    • Routing Logic: Automatically routing sensitive queries (political, human rights, censorship-related) to models with stronger neutrality guarantees (e.g., Apertus, Llama variants) or applying strict red-teaming filters.
    • Transparency: Clearly labeling when a response originates from a model known to have censorship constraints.

    Why This Matters: For a privacy-first platform serving a global audience, the integrity of the information provided is as critical as the encryption of the channel. Mitigating these biases ensures Lumo remains a tool for liberation rather than an unwitting vector for state narratives.

12. Option turn off anthropomorphic thinking and text

    I am currently very ritated

    why? I am wasting time, energy, and most of all TOKENS because of lumo's anthropomorphic beheviour.

    I understand people love anthropomorphic AIs.

    Can we however have an option to turn if off?

    And i really really really hope i do not need to explain what anthropomorphic in Ais means.

    because i my suggestion is NEXT LEVEL

    as in thinking and the text.

    Lumo keeps repeating the same answers, or otherwise, without thinking even when explicitly told to stop.

    when it finally stops to thinking, more then half of the "thinking" are simple anthropomorphic related text.

    Oh User is frustrated because i did this and i should have not. I need to make sure i apologies to user. I need to make sure i acknolage. I need to this. I need to do that. <- absolutly NONE of them are relevant to the task. and albsolutly ALL of them occure each time Lumo finally thinks.

    We are wasting most of out time, energy, and resources, because of this anthropomorphic elements in an AI.

    or what, is it a crime, heath risk, fraud, abuse, something? that an ais is not constanly determin how to "not offend" someone who is explicitly telling it to stop with this commenteries about what it did, what it did wrong, apologies, acknolagements, what it will do, as in reassurances, and ..... Did i make it clear? ALL of this, even if they are NOT in the output, they are if you simple check the thinking. And this happens alll the time. Insted of Lumo chekcing the tast, or instructions, or otherwise, it preocupised with anthropomorphic beheviour.

    For proton: I hope you understand that I am not talking about preferences but about the fact that a paid product is wasting time, mental energy, is getting absurd for not reason, it's producing text that is unsolicited, unproductive, ilogical at time AND it is PREVENTING anything to progress:

    You are right, i should have not, i will from now

    Here is again what i just wrote because I run out of tokens or time to actually proccess the task

    I am currently very ritated

    why? I am wasting time, energy, and most of all TOKENS because of lumo's anthropomorphic beheviour.

    I understand people love anthropomorphic AIs.

    Can we however have an option to turn if off?

13. Feature Request: “Auto‑Websearch” / “Always Enable Websearch” in the Personalization Tab

    Hey Proton team,

    thanks for the awesome Lumo 1.2 update! The new personalization options are super handy. To make Lumo’s answers truly real‑time, could you add a toggle under Personalization called “auto‑websearch” (or “always enable websearch”)?

    When turned on, Lumo would automatically pull in up‑to‑date info for any query that needs fresh data—no extra steps required. This would be a game‑changer for users who rely on accurate, real‑time responses.

    Appreciate the consideration!

14. Add the option to add knowledge (RAG) to custom Lumos and Projects

    Having additional knowledge (RAG) to a custom Lumo and/or Project is really useful. One can add specific files/websites/documents for different types of custom Lumos or Projects.

    As an example:
    - custom Lumo acting as an expert for a product line - add the documentation for the product line as knowledge.
    - custom Lumo acting as an expert in egovernment serivces - add the website of the egovernment services as knowledge
    - a Project for personal finance - add invoices, or income reports as knowledge
    - a Project related to planning an event - add offers, suggestions, plans as knowledge

    At least the following types of knowledge should be available:
    - Uploaded files (documents, text files, PDF files (with OCR option), images, etc.)
    - URLs - websites, public repositories, etc. (to be re-fetched regularly, to be crawled for several levels (e.g. pointing to a github repo to index the content in the subfolders as well))
    - Proton services (e.g. folder from Drive, the whole Device, Mail, Calendar)
    - External apps / Connectors / MCP servers - e.g. Atlassian stack, other email and collaboration platforms, etc.
    - Project specific - project content - once there are several chats in a project, they should be part of the knowledge available and used for new chats in the same project

    Having additional knowledge (RAG) to a custom Lumo and/or Project is really useful. One can add specific files/websites/documents for different types of custom Lumos or Projects.

15. Automatically save chat responses to a document

    In my view, Lumo 2.0 should prioritize its core strengths—leveraging the scientific and technical expertise behind Proton's mission—rather than focusing heavily on image generation. Image creation requires significant financial investment, and many established competitors already serve this market extensively. While I understand there may be legitimate privacy concerns around processing images, it seems the choice to pursue image generation was driven by market trends in AI rather than staying true to the scientific and educational purpose for which Proton was originally founded. My suggestion would be to refocus development resources toward those foundational goals where Proton has unique value and differentiation. For example;

    Background:
    I am deciding at this time who to invest my time, information and money for ai services. I see the benefits of Claude and its ability of Coworker.
    What’s my issue.
    I want to use Lumo for my personal & business for knowledge management with Projects and Drive integration. Currently:
    index works beautifully, but saving responses requires manual copy/paste/upload.

    Requested Feature:
    Automatically save chat responses to a documents name it and to assign to Project folder I’m working in, into the Proton Drive,
    then index those files for future context retrieval without loading full conversation history.

    Thank you for your Suite, I have subscribed for mainly the vpn but have unlimited subscription. I don’t use extensively because the offering is still a bit raw. No sheet app for example or document app. So just waiting.

    Please keep advancing.

    All the best
    Andy

    Add a "Report Language Error" button in the Lumo chat interface that lets users flag language issues directly. After clicking, users choose a category:

    Strict — Pure nonsense/incorrect term. Generates a corrected, academically accurate response.

    Synonym — Suggest an alternative word/phrase and context where it fits better. Helps Lumo understand nuance, register and topic-specific synonyms.

    Humoristic — Witty alternatives and wordplay. Helps Lumo learn humor and puns in the local language (especially useful for users with a "Casual/Cheeky" Lumo personality).

    This feeds into Proton's language improvement pipeline, helping Lumo and Scribe produce more natural, localized output — especially for smaller languages like Norwegian, Danish, Swedish and Finish.

    Use case: When Lumo says "hundkur" instead of "hundkoja," the user flags it as Strict. When Lumo misses a pun opportunity, the user flags it as Humoristic — and Lumo gets funnier over time.

17. Abandon Lumo and use resources to address deficiencies in Proton's core secure IT services

    Of course, I have no idea how many people use Lumo or how valuable a business this is to Proton. I hope this suggestion may flush that knowledge out.

    Customers buy Proton services for its secure IT communications. That is - as far as I know - Proton's core business and its unique selling point.

    Many companies offer AI chatbots which - if they're ever useful at all (about which I have doubts) - improve through scale usage, something Proton seems unlikely to achieve, at least when compared to US behemoths.

    Proton appears to have a large development backlog in its core security offerings, if the list in this Proton Voice website is to be believed. Some core deficiencies have remained unaddressed for years. I assume (but don't know) that Proton, as well as other secure communications companies, are trying to deal with a flood of customers fleeing US services or who are nervous about a deteriorating security environment. If so, the demand will only increase.

    Proton makes secure IT better than it makes AI chatbots. Proton's reputation is in secure IT. I assume that Proton sells more secure IT services that AI chatbots. I suggest that AI chatbots are a lower priority for new and existing Proton customers than secure IT. I submit that the world does not need - and Proton is unlikely to sell - more AI chatbots, but the world does need - and Proton can sell - better secure IT services.

18. lumo extended files

    Subject: Lumo Feature Request: Support for .nix, .zip, and .tar.gz files 🚀Hi Proton Team! 💜First of all, thank you for building such amazing, privacy-focused tools. Lumo looks great and works incredibly well!I would love to share a small feature request that would highly benefit technical users like myself. It would be amazing if Lumo could natively view and handle the following formats:.nix configuration files.zip folders and archives.tar.gz archivesAdding support for these formats would make checking files much faster, eliminating the need to download or move them to external apps just to see what is inside.Thank you so much for your hard work and continuous improvements. Keep up the fantastic job!Best regards,c

19. iOS app swipe side bar on left

    I’d like to be able to swipe the left sidebar with my finger in the iOS app both in and out.

    Right now you have to tap the sidebar toggle.

20. Allow anonymous data sharing

    I know that Proton doesn't create/train its own AI model, but a good european alternative would be nice to see. As unpleasant as this might be, to create a good model, lots of data is needed. A great app is worth nothing without good models. The current market leader, openAI, uses user data to train their models and have a huge advantage.

    If my data is ever used for training, I want to give it to a company I trust (or think I can trust) to handle them carefully. And this is you. I would like to see the option to anonymously share the chats to help train/refine models. In the best case, only chats without inputs that would give away who asks would be used (this would need to be checked somehow).

    I know that this is probably an unpopular opinion, but we have to face the reality: If we want good open models, we need to provide our data.
