Lumo AI by Proton

keep at what you guys do, love this tool

It’s come along. At first it was pretty inconsistent and puked out easily. As of June 2026, it’s good. I mix between several AI apps depending on what I’m doing and the free limits. Lumo is in steady rotation now since I pay for Proton. Nine or so months ago wasn’t a consideration.

I beg you please allow text resizing! Also landscape mode would be nice.

I’m paying for the service, but I’m not receiving any of the features.

I love Proton’s products and this one is built with to same anti-spyware standard as the rest of their quality products. A really great app.

The app crashes or doesn't do much. Appreciate the privacy not the engineering.

App seems to work well but not sure if "Assistance from Europe" is a good ad slogan. Thinking about Europe only "censorship" and "woke-ism" comes to mind. Who would want that? If assistance is needed then probably more likely IN Europe rather than FROM Europe. Just a thought.

I encountered a bug where promotional pop-ups (invite-a-friend ads) would appear repeatedly and erratically every time I opened the side menu. However, I found a solution: clicking the "Invite a Friend" button at the bottom of the menu once seems to fix the UI and stops the glitch. The app is working perfectly now. I wanted to share this fix to help the developers and other users. Great app!

The AI often gave defensive, biased answers, and I often had to fact check and correct it. It’s like arguing with a redditor, denying true objective facts and reframing reality in an effort to not be offensive. I told it not to sugar coat, and it gave me diabetes. The training data is from 2024. Very decent for non-political conversations. I think it gives you bad answers on purpose to make you respond more so that you reach your weekly limit faster pushing you to pay. Proton is great with everything else but this product is skippable. I appreciate the focus on privacy, but the free version needs to be more robust before I would spend money on it.

Upon first opening, on iPhones with Display Zoom enabled there are layout issues… please test with Display Zoom. Also, text size for the response area does not work with iOS’s Text Size control (like for people with vision needs), so the text is really really small. Please make it either respect iOS Text Size changes, or give an option in the app to change text size. Please (and this goes for all your apps)… use a little imagination with your icons. So many developers using white backgrounds… it’s lame and looks unfinished. I do love the cat though! It gives a lot more personality than other chat bots and I enjoy his animation. It makes this app a lot more fun. Thank you for listening to my feedback.
