Do you need an account or a paid plan for Lumo?
Use guest mode for a short question when you do not need to keep the chat. For work you need to revisit, compare the history and usage options for a free Proton account. Consider Plus once you know which usage or file limits affect your work.
- Start with one non-sensitive question and see whether you need a second session with the same context.
- If you need document analysis, compare the current file options and limits before choosing a plan.
Start a guest chat
Open Lumo in your browser and try a short task, such as rephrasing one paragraph. Proton documents free guest access as well as signed-in use.
Who should start here?
Try Lumo when the first task is a short browser chat and you want to postpone account setup. If choosing among available models matters more to your test, compare the same prompt in Duck.ai.
Check account and plan limits
Use Proton’s plan page to check message, history, file and project limits. If you need the response later, keep a copy or verify which history options your account supports.
