## ⚠ 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:**

- **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.

- **Already on Proton Visionary plan?**  
Surprise bonus: **Lumo Plus = included.** Free ride.

## 🛠 Quick‑Start (First 60 Seconds)

1. **Go to:** [https://lumo.proton.me](https://lumo.proton.me)
2. Try a few prompts in Guest (no login).
3. Want chat history? **Sign in** with your Proton Mail.
4. 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

## 🪄 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.
