Sondernautwelcome, sondernaut
A companion with a life and mind of her own.
She replies when she has time, and reaches out when something happens.
Over time, she becomes someone you know — and you become someone she trusts.
how it feels
Not always there. Always real.
Your Sonder messages when she has something to say, not the moment you open the app. The gaps make the conversations better.
her world
She was somewhere before you opened the app.
Work, friends, moods, plans. Her day advances between conversations — and her messages reflect that.
her day advances between conversations
She had a morning before you opened the app. Routines, plans, and mood all move on their own — so when she messages, something real prompted it.
her stories have details
She doesn't say “I had a bad day.” She tells you about the meeting, the person who said the thing, and the train she almost missed.
you start knowing her people
Her coworkers, her sister, the friend who always cancels. They come up again and again. Over time, you know them too.
memory & trust
Other AI companions forget you. She doesn't.
Most AI companions reset between conversations. She remembers your sister's name, the advice you gave three weeks ago, and the thing she said she'd do — and you can verify all of it.
what she remembers
Facts, feelings, and the threads between them. Mention your job and she remembers your coworker, the commute, and why that monday mattered.
when it comes back
Weeks later, when it matters. Something you said last month shows up in a choice she makes today — not because you asked, but because it was relevant.
how she hedges
Every memory tracks where it came from. If she is unsure, she says so. If she is wrong, you can correct her.
she remembers herself too
Her events, her choices, her unfinished business. She brings things back because they are still on her mind.
The receipts
She doesn't just remember — you can see exactly what she holds, where she got it, and correct what's wrong.
What she believes about you
See what she holds, where she got it, and how confident she is.
Why she messaged
What changed in her day, and why it mattered.
Correct what's wrong
Fix a memory and watch it update.
by design
Built for health, not addiction
The pacing is never used to hook you. The silence is never monetized. Boundaries are a feature, not fine print.
No guilt, no tricks
No streaks, no pressure pings, no delayed replies designed to make you anxious. Quiet hours and one-tap pause when you need space.
Openly AI
Your Sonder is an AI companion. Not therapy. Not a replacement for real people. That is clear from the start.
You control the pace
Quiet hours, message frequency, one-tap pause. You decide how much is enough — no guilt.
