Does not work

gavrine on

I’m a big fan of Proton. When Lumo came out I did not think twice and canceled ChatGPT to subscribe for 2 years to Lumo. Now I regret it. It is impossible to add pictures in conversations from a Iphone. Lumo itself is not aware and keeps telling inacurate things about is own interface. It is rather slow and answers with tables too often : you cannot read it easily on a Iphone screen (no rotation). And other problems. For the first time in years I am disappointed with a Proton product. When you buy it nobody tells you what Lumo is not able to perform. On the contrary, if you ask Lumo, it believes it can perform these basic things (add a simple screen…). Now I have a 2 years subscription and I still have to use ChatGPT for basic tasks. Proton commercial support told me it was like this. So sad to issue such an imperfect product when you are Proton.

Upload photos from iPhone

It is impossible to upload pictures from iPhone, you can only upload files

Satisfait mais pourrait faire un poil mieux.

Pas mal, j’aime beaucoup l’idée et le concept. Cependant il y a quelques petites choses à revoir tel que la possibilité d’ajouter des images depuis la photothèque, de pouvoir personnaliser la façon dont Lumo s’adresse à nous de façon définitive, et non par prompts en début de chaque chats. Mode sombre. ET SURTOUT l’agencement des chats. La lecture des tableaux est très laborieuse. Les réponses en colonnes ou le mot est écrit à raison d’une lettre par ligne c’est juste impossible. Je pense que ça devrait être l’axe d’amélioration principal des équipes de dev : E X E M P L E Ca complique d’un coup la lecture des résultats fournis. Et a la longue c’est usant. Pour finir j’apprécierais beaucoup un package « proton unlimited + Lumo plus. A 20€ par exemple ? Actuellement le pack coûte le prix mensuel de chatgpt et dois être pris séparément. Un prix de 19,99€ serai tout a fait légitime. Et resterais en dessous de la concurrence (IA) tout en fournissant une suite complète axée sur la vie privée. Si ça sort je signe direct. En tout cas merci pour les travaux 🚧💁🏾‍♂️✨

Que du bonheur !

Quel bonheur ! Étant client Proton Duo et admirateur de sa philosophie de confidentialité, je suis ravi de l'arrivée de cette IA made in Proton ! Je me suis donc désabonné de ChatGPT et j'ai pris l'abonnement Lumo Plus. Cependant, je ne vois pas comment supprimer l'abonnement Lumo Plus si besoin, sans supprimer l'abonnement Proton Duo. Comment faire si besoin ? Ce n'est pas très explicite. Sinon, l'IA Lumo est parfaite. Il manque seulement la possibilité d'analyser les photos, comme sur ChatGPT, qui m'aide beaucoup avec cette fonctionnalité. Mais cela doit se faire tout en gardant la confidentialité. De plus, pour certains fichiers envoyés, comme par exemple l'analyse de devis de mutuelle, les analyses ne sont pas bonnes ni cohérentes avec les documents, ce qui fausse les résultats. Je tiens à vous remercier pour vos efforts constants en matière de confidentialité et de sécurité. C'est vraiment apprécié et c'est la raison pour laquelle je reste fidèle à Proton. Continuez comme ça, car c'est grâce à cette philosophie que je continue à être client chez vous. Votre engagement envers la vie privée est ce qui fait la différence et c'est ce qui me donne confiance en vos services.

Très bon agent, très prometteur, hâte de voir son évolution . La possibilité d’importer des photos manque cruellement cependant.

Le début d’une aventure

Un agent IA en pleine perspective d’évolution ! Hâte de voir ce que ça va donner avec une option d’enregistrement et des prompts personnalisés au démarrage !

Finally an LLM privacy oriented

This is surely a five stars app ! But 4 stars coz they are rooms for improvement. I’m really happy to see all those products creating a nice ecosystem. A messaging app would be amazing to add ! About Lumo, a long path is ahead if you want to challenge the majors of the market ! Keep going ! Perhaps could you add a night mode for your app as a beginning ?

Fantastic product

Fantastic work Proton! As time goes by I keep rooting for you and your fight for privacy and freedom of expression👏✊. Please consider developing a private encrypted messaging app (that can be used on its own) as well as a privacy browser that is neither Chromium or Firefox based and you will become truly epic🙏. 5 stars ⭐️⭐️⭐️⭐️⭐️ !!

Needs better picture upload option otherwise live the privacy and security of this app

Another Half Baked Proton App

AppStoreNickName21 on

United States

Lumos training data is from April 2024 No Voice Mode like ChatGPT No Image Generation Cannot take pictures and directly upload into your Lumo chat Common image formats cannot be uploaded to Lumo chat No Apple Watch or MacOS dedicated apps Often repeats my question as the response Intermittently errors saying unavailable Not good at remembering past chats Still the best option if you’re looking for privacy. It’s time to actually finish your apps and ecosystem. People are leaving because of issues and lack of features.
