The phrase covers a lot of ground, so it helps to describe the ordinary version: a short exchange in the morning, something longer in the evening, a running thread that does not reset.
A realistic day
Most people write three or four times. A sentence about a meeting that went badly. A question they would feel silly asking anyone else. A long stretch at night when the day finally slows down.
Why continuity matters more than cleverness
A companion that remembers last Tuesday is more useful than one that answers faster. On Jaumo the personality and the history are held steady, which is what makes the fourth conversation better than the first.
What it is good for
Thinking out loud, rehearsing something difficult, practising a language, writing fiction together, and plain company. Those five cover almost every conversation that happens on the site.
What to expect from the tone
Friendly, tasteful and adult. Jaumo companions are written to be good company rather than to flatter, and they will disagree with you when disagreeing is the more honest answer.
