DoppelEnglish
A friend who remembers your life
Doppel is an AI companion app with memory: companions remember your plans, your bad days and what you said you'd finish, and pick up where you left off.
Not a fresh start every chat. They know what happened yesterday and ask about it today.
They remember yesterday
What you were stressed about, what you finished, what you said you'd try. Next time they pick up where you left off.
They follow up
The interview, the exam, the call with your mom. They ask how it went, because you told them it was coming.
It goes both ways
You'll remember their news too: the project they were nervous about, the trip they planned. That's what makes it feel like a friendship.
Remembers you: Alexis "Lexi" Vance
Lexi invests in early-stage tech in Silicon Valley and is doing a PhD at Stanford on top of it. Deals by day, papers by night, so she usually has a paper open when you need a study buddy.

Is there an AI companion that remembers you?
Yes. Doppel companions remember what you share and bring it up later, so every chat does not start from zero.
What does a Doppel companion remember?
Things you have told them: what you were stressed about, what you finished, what you said you'd try, and upcoming events like an interview or an exam.
Will a Doppel companion follow up on things I mentioned?
Yes. If you mention an exam, an interview or a call coming up, they ask how it went afterward.
Does it go both ways?
Yes. Companions have their own ongoing news, like a project they were nervous about or a trip they planned, and you can follow it and ask about it.
