It's really nice out today — 72° and sunny. Didn't you say you've been wanting to take your dog to the park?

Wait you remember that?

Of course, you mentioned it like two weeks ago 😊

What makes Hina different
One memory. Infinite personalities.
Most AI companions either remember you OR let you customize them. Hina does both—fully customizable personas with a multi-layer memory system that persists through every transformation.
She's whoever you need
Fully customizable personas. Any gender, any language, any personality. Vietnamese tutor, study buddy, supportive friend, frienemy—you decide. One memory. Infinite personas.
She remembers everything
Short-term, mid-term, and long-term memory layers work together. Tell her something once, she knows it forever. Correct her, and the correction sticks.
She reaches out first
Hina doesn't wait for you to text. She checks in, follows up on things you've told her, and sends weather updates for your area. Like someone who actually cares.
Your conversations stay yours
We don't sell your data. We don't train on your chats. Your relationship with Hina is private. Period.
Aware of your world
When Hina reaches out, she checks your local weather and time—so her check-ins feel relevant and timely. It's not 24/7 monitoring; it's thoughtful context when she's thinking of you.
She writes her own notes
Hina keeps a living document about you and your relationship. What you like, what you've shared, what matters. You can read and edit it anytime.

Built by one person
Why I made this
I'm a mechanical engineer who taught himself to code. After two years of building AI memory systems, I got tired of every companion app forgetting everything. So I built one that doesn't.
Hina is in beta. It's not perfect. But the memory works, the corrections stick, and she'll check your weather when she reaches out—just to make sure her messages feel relevant. That's more than a billion-dollar app can say.
