If you have heard about AI chatbots and wondered whether you can trust one with personal questions, this guide is for you. By the end, you will know how to open Lumo, send your first message, get a useful answer, and understand what Proton says about keeping your chats private.

💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.

✅ Before you start

An internet connection and a web browser on a phone, tablet or computer. Lumo is used through the browser in this guide.
A Proton account, which you may need to create or sign in with. Proton's official site is the place to do this. Search for "Proton Lumo" and make sure the page you open belongs to Proton.
A free or paid plan. Proton offers Lumo with a free tier and paid plans that unlock more. Check the official pricing page for current details, because some features may need a paid plan.
About 15 minutes for the whole guide.

Step 1 of 5

Open Lumo from Proton's official site

Go to Proton's official website and find the Lumo section. You can search for "Proton Lumo" in your browser, then check that the result leads to a Proton address before you click. Once the page loads, look for a button like Try Lumo or Get started. If you are asked to sign in, use your Proton account. If you are asked to create one, follow the on-screen steps and write your password down somewhere safe.

If the layout looks different, don't worry. Proton changes its pages from time to time. Look for any link with the word "Lumo" and open that page instead.

✅ You'll know it worked when

you see a chat screen with a message box at the bottom, where you can type your questions.

Step 2 of 5

Send your first message

Click inside the message box at the bottom of the screen. Type a simple, everyday question so you can see how Lumo responds. Then press Enter on your keyboard, or tap the send arrow beside the box if you're on a phone or tablet. Your message appears in the chat, and Lumo's answer starts to appear below it, usually word by word.

Keep your first question light and practical. Think about a question you would normally search for.

💬 Try typing this"Give me five easy dinner ideas I can make in under 30 minutes with chicken and rice."➤

✅ You'll know it worked when

your message shows up in the chat and a written answer appears underneath it.

Step 3 of 5

Ask a follow-up to refine the answer

A good AI chat works like talking with a helpful friend: you can keep going. If an answer is too general, ask for changes in the next message. Lumo keeps the earlier part of the conversation in view, so you can say things like "make it shorter" or "for a family of four." If the answer misses the point, don't start over. Add one or two details and send it again.

Remember that a chat assistant can make mistakes. It can sound confident and still be wrong, so check any important facts with a trusted source.

💬 Try typing this"Make those dinner ideas vegetarian, and list the ingredients for the first one only."➤

✅ You'll know it worked when

Lumo's new answer reflects your change instead of repeating the first answer.

Step 4 of 5

Use Lumo for a real task

Now try something that matters to you. Lumo can help you draft a message, plan a trip, summarize a long paragraph you paste in, or explain a topic in plain language. Describe your situation clearly: who it is for, what you want, and how long or formal it should be. You can also paste text you already have and ask Lumo to tighten it up.

Be honest with yourself about what Lumo cannot do. It can draft an email, but it cannot send that email for you, and it cannot see your inbox unless you paste the text in yourself. It also cannot replace a doctor, lawyer or financial advisor, so use it to prepare questions for those professionals, not to make final decisions.

💬 Try typing thisType your own details into the dashed boxes, then copy."Help me write a polite message asking my landlord when will be fixed, in about four sentences."➤

✅ You'll know it worked when

you have a draft you can read, edit and use yourself.

Step 5 of 5

Understand Lumo's privacy promise and protect yourself

This is the step where Lumo is different from many assistants. Proton says Lumo is built so your conversations are encrypted, which means scrambled in a way that makes them hard for others to read. Encryption is like putting your letter in a locked box before mailing it. Proton also says it does not use your chats to train its AI models. These are Proton's own statements, so read its official privacy pages for the full details.

Privacy still depends on your habits. Do not type passwords, bank account numbers, Social Security numbers or other secrets into any chat, even a private one. Before you share personal details, ask yourself whether you would be comfortable seeing them written on a sticky note in a shared office.

💬 Try typing thisType your own details into the dashed boxes, then copy."Summarize this paragraph in two sentences, and I'll remove my name first: ."➤

✅ You'll know it worked when

you can explain, in your own words, what Proton says Lumo protects and what you should still keep out of the chat.

⚠️ Common mistakes

Mistake: Trusting every answer without checking. Lumo can be wrong. Fix it by verifying names, dates, numbers and health or money facts with an official source.
Mistake: Pasting in sensitive information. Privacy features don't make every detail safe to share. Fix it by leaving out passwords, account numbers and other secrets, and removing names where you can.
Mistake: Asking one vague question and giving up. Short prompts get generic answers. Fix it by adding who the answer is for, what you need, and how long it should be, then following up.
