One‑Line Flow: Open → Ask → Evaporate (with encryption).
lazy? – What Even Is This?
- It’s an AI chatbot from Proton (yep, the email guys).
- 100 chats/week free, zero-access encryption.
- Guest mode = no login, no saves, just ask and vanish.
- Runs only on Proton‑owned EU servers, no third-party clouds.
- Not trained on your data. Not even their team can read your stuff. [paranoia-approved]
1% Tricks They Won’t Mention on Ads
-
Stack the free chats:
- Hit 100/wk limit? Switch to Guest → boom, 25 more.
- Hit Guest cap? New browser, new IP, maybe more. [hypothetically speaking
]
-
Ghost Mode toggle:
Chat like a ninja. Your convo is gone once you leave.
Even when logged in. -
Use Proton Drive for uploads:
Send your sensitive file → ask Lumo to analyze it = encrypted in + out. -

Surprise bonus: Lumo Plus = included. Free ride.
Quick‑Start (First 60 Seconds)
- Go to: https://lumo.proton.me
- Try a few prompts in Guest (no login).
- Want chat history? Sign in with your Proton Mail.
- Need mobile? App Store / Google Play → “Lumo by Proton”
Warnings
- Guest chats = poof. Nothing saved. Not even your weird typo.
- No file upload in Guest mode. Sign-in needed for attachments.
- Models are open-source, so answers may differ vs OpenAI/Claude.
- No jailbreaks, no hallucinations playground. It plays clean. Like… too clean.
Reality Check
- Not ChatGPT-fast. It sips tea between answers.
- Doesn’t make up wild stuff just to look smart.
- Translation, summaries, privacy research = great. Coding? Meh.
Models Inside (For Nerds)
- Mistral Small 3, OLMo 2 32B, Nemo, OpenHands 32B
- Everything routed via Proton’s EU-only servers
- No Google, no Azure, no AWS peeking through the blinds

Output Example
“Summarize this legal PDF in 5 bullet points.”
Lumo:
– This clause allows company X to spy on users.
– This clause tries to hide that.
– This clause says “trust us.”
– This one removes liability.
– This one basically goes “surprise, you’re the product.”
Final Thought
If ChatGPT is the class clown, Lumo is the privacy kid eating lunch behind a VPN.
He’s quiet. He’s smart. He deletes everything. Probably encrypts his diary.
Use it when you want your questions to disappear like your social energy at a party.
