Ask Blu · Pro
A buddy who remembers what matters to you.
Blu remembers the big presentation, the friend you’re worried about, the walk that helped last week. So every chat picks up where you left off, at 2pm or 2am.
Blu is an AI companion, not a person.
Blu
Remembers your week
How did the presentation go? You were dreading it on Monday.
Honestly better than I thought. Still drained though.
That makes sense after a week of bracing for it. Want to log a colour, or talk through the drained part?
Log it. Teal I think.
Emotional Forecast · Pro
