About Lumis AI
What is Lumis AI?
Lumis AI is a free AI assistant designed for everyday use. Whether you need help writing an essay, debugging code, researching a topic, solving math problems, or brainstorming creative ideas — Lumis AI is built to help you get it done fast.
Unlike other AI tools that hide their best features behind expensive paywalls, Lumis AI gives you powerful capabilities on the free plan: three AI modes, image analysis, web search, and code generation with live preview.
How does Lumis AI work?
Lumis AI is powered by advanced language models from Groq, giving you fast and accurate responses. You can choose between three modes depending on your needs:
Fast Mode gives you quick, concise answers in under 2 seconds. Thinking Mode provides deeper analysis and reasoning for complex questions. Tasks Mode breaks down any project into step-by-step action items.
Lumis AI also supports image uploads — drop in a screenshot, photo, or diagram and ask questions about it. When you ask about current events or trending topics, Lumis AI automatically searches the web to give you up-to-date information.
Who is Lumis AI for?
Lumis AI is built for everyone — students, developers, writers, researchers, professionals, and anyone who wants a smart AI assistant at their fingertips. It works on desktop, mobile, and even has a Mac menu bar app for instant access.
