What Lumo can help you with
Lumo is a simple chat interface backed by AI. You can type anything in the chat and Lumo will answer you with a helpful response.
Here are some of the ways Lumo can help you:
- Get answers to questions about almost anything. Lumo has a massive store of knowledge about the world, and you can turn on the web search feature to get the most up-to-date information.
- Brainstorm ideas, create plans toward any goal, or prepare a schedule
- Check if you’ve filed your taxes correctly
- Upload sensitive legal files and have Lumo summarize them.
- Translate text into multiple languages. Lumo supports English, French, German, Spanish, and more.
- Improve your writing or edit text for grammar, spelling, and style.
- Offer coding assistance, debug code snippets, and answer mathematical problems.
- Get recommendations for books, movies, or music.
Keep in mind that since Lumo is based on sophisticated algorithms, it can’t “think” in the way people can. It produces responses to your chats based on statistical properties of language. For that reason, the model can sometimes produce inaccurate responses, especially when it comes to recent events or highly specific queries. You should verify anything before you use it outside Lumo.
Proton has implemented safeguards in Lumo to prevent harmful or offensive responses, but if you see anything problematic please report it to our team.
How to start a chat
- Open Lumo by going to lumo.proton.me (new window)on any web browser, or by downloading our mobile app on iOS or Android.
