Personal OS · Android · On-device

Your time. Your space. Yours alone.

A private personal OS that captures every meeting, message, and thought — and helps you keep your promises. The intelligence runs on your device. Sharing is end-to-end encrypted. Default deny, always.

What it does

One surface for the people, places, and promises that matter.

Time & Space replaces the constellation of notes apps, todo lists, and reminder tools with one coherent surface that respects the difference between work, family, and self.

1

Capture, in your voice

Hold to dictate, share from any app, or forward an email. Voice notes are transcribed on your phone, never in the cloud.

2

Understands who's who

Builds a typed graph of the people in your life — work, family, friends — with relationships you confirm. Never silently assumed.

3

Right time, right place

Notifications respect your meetings, your focus, your hours, and where you actually are. Never too early, never too late.

4

Catches what others say

When your spouse says “don't forget X” on WhatsApp, it lands in your inbox in seconds — for you to accept with one tap.

5

Promises kept

Extracts commitments from meetings and chats. Surfaces what you owe, what you're waiting for, and what won't fit in your week.

6

Calendars, unified

Work, personal, and shared calendars become one coherent view of your day — without leaking detail across contexts.

Private by architecture

The intelligence runs on your device. The cloud holds encrypted blobs only.

Privacy isn't a checkbox here — it's the design. Time & Space treats your data as yours. Default deny is the law.

  • On-device LLM. Notes are extracted on your phone using Gemini Nano. Nothing leaves the device unless you share it explicitly.
  • Default deny. Every node is private until you explicitly share. Even new fields you add later default to private.
  • End-to-end encryption. Sharing uses MLS — the same cryptographic protocol designed for private group messaging. Our relay holds ciphertext only.
  • Field-level visibility. Share that you have an appointment without sharing what it is. We mean it.
  • View as them. Before anything goes out, see exactly what each audience can see. No black boxes.
  • Provenance always. Every fact tracks where it came from. Nothing is invented; everything can be retracted.
Sharing

Even within family, some things stay yours alone.

Most apps treat “family” as one bucket. We don't. Audiences nest, and each share is field-level: you control exactly which parts of a thought, an event, or a promise are visible to whom.
