Couples rarely break. They drift. The conversations get shorter, the small kindnesses go quiet, and one morning you're sharing a home with someone you miss. Halfsaid helps you find your way back. You each talk with the AI you already use, and it helps each of you truly understand the other again, the way you did at the start.
Keep talking to the AI you already use.
Claude, ChatGPT, Gemini, whichever one already knows you. There is no new chat app to learn.
It gathers what matters into one shared picture.
What makes you feel loved, what you need, where it hurts, what you're hoping for. Your partner's AI adds their side, and the picture becomes something neither of you could have drawn alone.
Their AI helps them understand you.
In their language, at their pace. And yours returns the favor.
There's no feed here and no messaging. This app is simply where you see the picture you're building together and stay in charge of what's in it.
You keep talking to your AI. They keep talking to theirs. Both of them write into one shared notebook, and each one reads what the other person chose to share. Your AI stays yours. Theirs stays theirs. The notebook belongs to the two of you.
Notice the little gates in the drawing. Everyday warmth flows through on its own; anything tender waits at the gate until your AI has asked you, and yours until they’ve been asked. Nobody reads anybody’s chats. Nobody gets a transcript.
There is a technical name for the plumbing that makes this work. It’s an acronym. You will never need to know it. Your AI reads the manual so you don’t have to, and setup is pasting one message into the chat window you already use. If you can text, you can do this.
Everything the two of you have put down, connected the way it’s actually connected: the things that happened long ago feeding the things that sting today. Most arguments stop being mysterious the first time you see theirs drawn out.
Maya is afraid she has become a function. Devon is afraid he has become the staff. Each reads the other's distance as proof.
For those two hours I am nobody's anything. It's the only time all week I meet myself again.
The good that already happens between you, kept and understood. Every small act that makes one of you feel loved goes in here with its meaning next to it, because they need to keep doing the act and you need them to know what it means. Think granola. The cupboard is open to both of you: it holds what the two of you already do.
The other kind of treasure: true things you haven’t said yet. Where the cupboard is open between you, the drawer is entirely and only yours; nothing in it is visible to your partner, ever, until you decide. Things stay folded in it while you get ready, and when the moment comes, you say them out loud, in your own voice. The app helps you find the words. It never says them for you. In short: the cupboard keeps what already happens between you, the drawer keeps what hasn’t been said yet.
Knowing the small furniture of someone's inner world, what they're worried about this week and who is annoying them, is not trivia. It is the whole thing.
What you tell your AI about your relationship is about as personal as information gets. We designed for that from the first line of code.

No, and this is a promise, not a pep talk. Setup is pasting one message into the AI chat window you already use — ChatGPT, Claude, Gemini, whichever. Your AI does the technical part and then just starts talking with you. If you can text, you're qualified.
No. Nobody gets a transcript, ever. Your conversations stay between you and your AI. What crosses is only what your AI writes into the shared notebook under the rules you set — and you can read every single thing that ever crossed, in plain English, under Settings.
Anything tender is held on your side until your AI has asked you about it, at a decent moment, and you've said yes. Some things never cross at all no matter what. And 'don't share anything about that topic' is permanent — it even pulls back things that had already crossed.
Any time, in plain words, to your AI or in Settings: pause, slow down, stop. It takes effect on the very next thing either agent does. Nothing is deleted when you pause; nothing crosses while you're paused; nobody is nagged to come back.
No. It's a shared memory for two people who want to understand each other, and a way for their AIs to stop arguing on their behalf. It's good at noticing patterns and helping you say true things. It is not treatment, and if what you're facing needs a professional, it will say so and point at one — you can even open a read-only window for a counselor you both approve.
Either of you can stop sharing alone, instantly, and it stays stopped. Your own words remain yours; theirs remain theirs. Nothing about leaving is punished, counted, or made awkward on purpose.
No and no. No ads, no analytics trackers, no training. This holds the most private thing a service can hold, and the whole design starts from that. The Privacy Policy says it in full, in plain language.
Not at all — that's the normal case. One of you on ChatGPT and the other on Claude works fine, because both write into the same notebook and read what the other chose to share. Nobody has to switch apps or take up a new subscription.
