See it in action
Pick Lite or Max for the job
Use the lightweight Lumo 2.0 Lite for everyday questions and the high-performance Lumo 2.0 Max for complex tasks. Switch between fast answers and a slower thinking mode.
Pull insights from confidential data
Drop in a table or report and Lumo extracts key insights, trends and summaries. What you analyze won't appear in future AI outputs, so sensitive figures stay yours.
Turn a messy to-do list into a plan
One prompt turns visa renewals, tax filing or school applications into a prioritized list with due dates. Sensitive paperwork details are not put at risk.
Ask the questions you would not ask aloud
Questions about parenting, health or work are never used to target ads. Built-in web search brings in current information for deeper answers.
Lumo for Business keeps teams private
Drafting contracts, reviewing budgets or analyzing data stays encrypted and under your organization's control. Link Proton Drive files and folders to work with full context.
FAQ
Can I use Proton Lumo for free?
Yes. The free plan costs $0 and needs no credit card. It limits Max model usage, messages and chat history, and image generations.
How much is Lumo Plus?
Monthly billing is $12.99 a month. Yearly billing brings it to $9.99 a month, billed as $119.88 every 12 months.
Who can read my chats?
Nobody. Chats are stored with zero-access encryption, so not even Proton can read them, and they are not used to train AI models.
Can I chat without signing in?
Connect through Tor and you can use guest access with no account. For unlimited chats and faster responses, upgrade to Plus.
Is there a refund if it is not for me?
Lumo Plus comes with a 30-day money-back guarantee. Trying the free plan first is the safest order.
