Speak naturally
No diary. No entries. No streaks. Just you, speaking what is real, and Seity listening.
Voice app for iPhone and Mac
Untangle what's living in your head.
We carry so many thoughts inside us, letting them tighten into knots. Talk them through: Seity listens, responds out loud, and remembers what you said before, so you can return to the thoughts that keep looping.
Free public beta. Seity runs on your iPhone or Mac.
It remembers what you said.
Too much to do
You
I have too much on my plate and I don’t know where to start.
Seity
You named five things. The one you came back to three times was the talk on Thursday.
A week later
You
The talk went fine. Why was I so worried?
Seity
Last week it wasn’t the talk itself that worried you. It was the questions afterwards.
A decision
You
I can’t decide about the new job. The pay is better, but something holds me back.
Seity
You mentioned the pay twice, and the team not once. Maybe that’s where the doubt is.
A week later
You
I met the team today. I liked them.
Seity
Last week the team was the part you couldn’t picture. Now it’s the first thing you mention.
An argument
You
I had another argument with my sister, and I don’t even know what it was about.
Seity
It started when she cancelled the weekend. You said you’re always the one who makes the plans.
A week later
You
She called. I didn’t pick up.
Seity
Last week you said what hurt was always being the one who reaches out. This time she did.
What happens when you talk to Seity.
-
You talk
Say what’s on your mind, as messy as it is. No blank pages. No pressure to sound articulate.
-
Seity responds
It listens and responds out loud, so you can think something through without typing a word.
-
Seity remembers
Next time, it can pick up where you left off.
Things to talk through
- A decision you keep postponing.
- A conversation that went badly.
- A plan that only half makes sense yet.
- Whatever kept you awake last night.
Behind the conversation: an Inner World Model.
We’re building an Inner World Model: a living understanding of your recurring thoughts, emotional rhythms, and the landscape underneath your days. In practice, it is what Seity’s memory is designed for: bringing back what you said before and connecting the themes that keep appearing.
Return to a thought
Mention something you said last week. Seity’s memory is designed to bring it back.
On your iPhone or Mac
Speech recognition, responses, and the Inner World Model run on your device.
Before you start.
How is this different from talking to a chatbot?
Seity is built for one thing: thinking out loud and returning to what you said before. And its speech recognition, responses, and memory run on your iPhone or Mac.
Do I have to use it every day?
No. There are no streaks. Use it when something is on your mind.
Which devices can run Seity?
The public beta requires an iPhone 16 or newer, or a Mac with M2 or newer, and is available in English.
Is Seity a therapist or mental health app?
No. Seity is for personal reflection. It does not diagnose, treat, provide crisis support, or replace qualified professional care.
Seity is made by a10n, a small group of AI engineers in Amsterdam. It is not designed to keep you talking. Read our promise
Try Seity.
Talk something through on your own iPhone or Mac, and see what Seity remembers the next time.
Free during the beta. English only, on iPhone 16 or newer or a Mac with M2 or newer. Expect bugs and slow or imperfect replies.
