★★★★★ "your request was interrupted" - if the screen sleeps the request fails - if the screen locks sometimes incognito chats stay, other times they poof - lumo is dumber than qwen 3.8 the - app barely works on galaxy fold
★★★★★ On GrapheneOS, login always fails silently.
★★★★★ Same bugs, same issues in prompts.
26 of the 1 and 2 star reviews.
★★★★★ Pretty much useless currently.
★★★★★ esp since AI does frequently give wrong answers that require clarification.
★★★★★ Lumo is wrong far more times than it is right and I say that in regard to everything I have used it for.
22 of the 1 and 2 star reviews.
★★★★★ The app itself is really slow and takes forever to loadup even with good internet speed !
★★★★★ The UI is just horrible, the initial loading state flickers in and out, even flickering the theme from dark to like before it loads, and if you start typing it will just lose the keyboard focus once it loads.
★★★★★ lumo is slow, delivers ok information when done loading, and then they want money for more than 20 searches a month, there is no reason to have lumo when so many others are better and cheaper

★★★★★ You have about 1 week before my subscription expires.
★★★★★ expensive and ok at best.
★★★★★ Unfortunately I have to cancel and switch back to chatgpt or something similar because of how incorrect it is.
18 of the 1 and 2 star reviews.
★★★★★ I guess once you run out of your limited prompts, that's it.
★★★★★ Love Proton Apps BUT 2x Q a day limit cannot even answer ONE question!
★★★★★ Even within limited chats in one day, it made a range of mistakes & hallucinations: 9 errors in total which is too many.

★★★★★ I still cannot sign in anymore.
★★★★★ On GrapheneOS, login always fails silently.
★★★★★ I can't login to my proton account!

★★★★★ Update: I don't see the point of this app.
★★★★★ liked it , but after update it doesn't work stuck on how can I help chat/ prompt but after typing can't send it and can't access anything else or past chats nor settings.
★★★★★ It works well but it appears that some recent update removed my locally saved chats that I NEEDED for later...?
10 of the 1 and 2 star reviews.
★★★★★ If I lose all the work I paid for, I will be absolutely furious.
★★★★★ The UI is just horrible, the initial loading state flickers in and out, even flickering the theme from dark to like before it loads, and if you start typing it will just lose the keyboard focus once it loads.
★★★★★ Why need to signed in if still deleted.
18 of the 4 and 5 star reviews.
★★★★★ lumo takes a calculation burden off my shoulders when I'm in the design phase of an engineering project.
★★★★★ some aesthetic benefit to the app.
★★★★★ The only remaining complaint is a few visual/UX nitpicks - when I first bring it up, I see some overlapping boxes at the bottom, and most importantly, the icon at the top that opens the sidebar only mysteriously…
14 of the 4 and 5 star reviews.
★★★★★ Forking chats would be very useful as sometimes I want to take the chat in different directions.
★★★★★ It can still be helpful for searching.
★★★★★ It helps me enough when researching and Id rather have privacy but have to fact check a bit over slightly less inaccurate but everything is sold to data brokers.
13 of the 4 and 5 star reviews.
★★★★★ fast, accurate, and secure.
★★★★★ For me this AI works great, I've seen a lot of benefits but the biggest one is my improved efficiency.
★★★★★ works perfectly, its clean in the way it speak, reliable, customisable and simple as every ia should be.
12 of the 4 and 5 star reviews.
★★★★★ Once loaded it's pretty fast and doesn't block a lot.
★★★★★ Answers are fast amd reliable with minimal glitchiness.
★★★★★ Although not as fast as Gemini, but it can help me with DCF analysis fine!
8 of the 4 and 5 star reviews.
★★★★★ Easy to make a new chat to get on topic.
★★★★★ Lumo is hands down my favorite AI assistant—it's super easy to use and gives me total peace of mind with its rock-solid privacy standards.
★★★★★ The assistant is very helpful, and the app is intuitive.

Proton has made a good try with Lumo, however, it is far from the capabilities of Google's Gemini which can do far more and with far greater accuracy, although not perfectly all of the time. Hopefully, Proton can keep improving Lumo and in the future it can become more of a daily driver rather than an occasional tool. I tried Lumo plus by the way.
In recent months I had discussions with Lumo about subjects that sit on the borderline of philosophy and twentieth century psychology. I was impressed by its apparent intelligence and apparent astuteness. On one occasion I asked it about similarities between the poetry of Robert Frost and the paintings of Andrew Wyeth. Again its apparent intelligence was impressive, but when I tried to turn back to an earlier point in the discussion, Lumo lost the thread.
As a proton visionary user, I usually touch pretty much everything in the Proton ecosystem, but Lumo was something I didn't. I use AI agents all the time, but during Lumos infancy it honestly was a bit rocky and not worth - the trade off of security vs losing out on tons of features wasn't valid beyond select cases. I left it alone for awhile, decided to check back - I'm so glad I did. Way better now - memory, drive integration, coherent image generation, unlimited for Visionary - thank you!

I still cannot sign in anymore. When I do sign in nothing happens and it still says I am not signed in.
