You talk. Seity listens, responds, and remembers.

Seity is a voice app: you speak, and it responds out loud. Here is what happens in a conversation, what Seity keeps from it, and what runs on your iPhone or Mac.

Hear Seity 0:00 / 2:47

A short introduction from Seity

How it works

  1. You talk

    Open Seity and start speaking. No forms or prompts to fill in: just say what is on your mind.

  2. Seity responds

    Seity responds out loud to what you say. The aim is reflection: room to hear your own thoughts, without turning every experience into a problem to solve.

  3. Seity remembers

    Next time, it can pick up where you left off. Across conversations, the Inner World Model is designed to connect recurring thoughts, behavioral patterns, and emotional rhythms that are hard to see from the inside.

Keep your own rhythm

Start wherever you are. Pause, change direction, or come back another day. There is no daily target to meet.

The problem

Much of our inner world remains invisible from the inside. Thoughts repeat, emotional rhythms shift, and patterns quietly shape our days. Notes capture isolated moments. What is missing is a listener that remembers.

The Inner World Model

We’re building an Inner World Model. You talk out loud; Seity listens, remembers, and reflects. The aim is a living model of the patterns underneath your days, taking shape across conversations on your device.

In practice, it is what Seity’s memory is designed for: bringing back what you said before and connecting the themes that keep appearing.

No diary. No entries. No streaks.

What runs on your device

Speech recognition

Your voice becomes text on your iPhone or Mac.

Responses

The model that responds to you runs on the device itself.

Memory

The Inner World Model is built and kept on your device.

Designed for independence

Seity is not designed to keep you talking. We want to build something that helps you return to your own life with more understanding, without streaks, engagement loops, or pressure to stay.

The shift we’re working toward: from “I’m alone with this” to “I am being seen.” From unheard to heard, from stuck to moving.

Try Seity.

Talk something through on your own iPhone or Mac, and see what Seity remembers the next time.
