Lucian is a desktop assistant that lives on your Mac or PC. Say what you want the way you would say it to a person. It makes the folder, finds the file, cleans up the mess, writes the captions, and shows you exactly what it did.
macOS (Apple Silicon and Intel) and Windows. Use your own AI keys or let Lucian handle it.
Real screen recording of Lucian 1.0.22. No scripted UI.
Safe by default
When you say "delete the old screenshots", Lucian lists what it found, asks once for the whole step, and moves them to the Trash. Overwrites, moves, and risky terminal commands show a card before anything happens, and file edits come with an Undo. Nothing silently disappears.

Shows its work
Make a folder and you get a chip that opens it in Finder. Write a file and the path is a link. Caption a video and the new file is right there. Lucian answers like a person and hands you the thing.
Done. Your tax folder is on the Desktop.
Asks when it should
"Put my photos somewhere" gets you a short list of sensible options, each one a button. Clear requests just run. You stay in control without being interrogated.
Where should they go?
Built for big jobs
Ask it to compare three apps and Lucian spins up helpers that each dig into one, right inside the chat, with their own timers and a stop button. Then it merges what they found into one straight answer.

These are real requests, typed the way people actually type them. Lucian figures out the rest.
Bring your own AI keys for $20 a month, or choose a hosted plan and Lucian handles the models. Sign in, subscribe, done.
Download for macOS or Windows from your dashboard. The setup wizard asks for the permissions it needs and pairs the app to your account with a short code.
Type or speak. Lucian does the task on your machine, shows you what it did, and asks before anything risky.
Plans start at $20 a month with your own keys. Hosted plans include the models so there is nothing to set up.
