Memory

What Otto remembers

Everything here is used in every conversation, so replies feel personal instead of generic. Add the things that matter — your preferences, your people, how you like things done. Edit or remove anything, any time. It's yours.

Teach Otto something about you

One fact at a time works best — for example, “I take my coffee black” or “My daughter's name is Maya.”

Nothing remembered yet

Teach Otto your first fact above, and every chat from here on will know it.
