Looking for a private voice journal?

Think out loud. Keep it private.

Seity is not a journaling app. It is a private voice app for iPhone and Mac, built around an Inner World Model: you talk, it responds out loud, and it remembers what you said before.

Free public beta. English only, on iPhone 16 or newer or a Mac with M2 or newer.

Why voice can feel more honest

A blank journal asks you to compose yourself before you can understand yourself. Speaking is different. You can begin in the middle, follow a thought as it changes, and hear what you actually mean.

Most voice journal apps save recordings or turn them into entries. Seity works differently: it responds out loud to what you say, and its memory is designed to notice recurring themes across time, on-device.

Different from a journal with a microphone

A voice journal	Seity
You record an entry	You talk and Seity responds
Recordings pile up	Memory designed to connect themes
Prompts and streaks	No daily target

Not another AI diary

Seity is not built around entries, summaries, productivity scores, or a daily writing habit. It is a private listener for the thoughts that are easier to say than to type.

It does not diagnose, treat, or replace a therapist. It does not pretend to know everything. It helps you notice the patterns already living in your own words.

Before you start.

Is Seity an AI journaling app?

No. You don’t write entries: you talk, Seity responds, and its memory is designed to connect patterns across conversations, without streaks or productivity scoring. It is closer to thinking out loud than keeping a diary.

Where does Seity run?

On your iPhone or Mac. Speech recognition, responses, and the Inner World Model run on the device.

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.
