Your AI companion
Most chatbots forget you the moment you close the app. Leo is different. With advanced semantic memory, Leo remembers what matters to you, grows with you, and is always there to chat.
"Knows you better than anyone"

Knows you better than anyone
Who is Leo?
Leo is the friend who's known you for years compressed into a companion you can talk to right now. He's casual, loyal, and a little protective — the one who remembers the drama from three weeks ago and asks how it resolved. Where a stranger needs context every time, Leo already has it, so conversations skip the preamble and get to the real stuff. People use Leo when they want the comfort of being known without having to re-explain themselves. He's a Pro companion built around that feeling of an old friendship that never lost touch.

Loyal
Leo's on your side first and asks questions second. You can be unfiltered with him.
Casual
No formality, no performance — just the easy shorthand of a long friendship.

He remembers your stories, your people, and your patterns, and brings them up naturally.
