One prompt.
Anything.

Type or talk. SlyOS works out what you mean and just does it — texts people, sets reminders, opens apps, writes, posts — often several things at once.

Your whole life,
remembered.

It imports your chats and learns your people, weaving everything into a living memory you can simply ask — "what did Papa say about the trip?" "Do I know any VCs?"

Get it

Install in 3 steps

No computer needed on your end — just the file and your own key.

↓ Download SlyOS.apk

Android 10+ · ~50 MB

On your Android phone

  1. Tap Download, then open the file. Allow "install from unknown apps" once, then Install.
  2. Open SlyOS → the setup wizard takes your Anthropic key, then optional profile & imports.
  3. Press Home → SlyOS → Always. It's now your home screen.
🔑 You bring your own Anthropic API key.

Get one free at console.anthropic.com → API Keys → Create Key (starts with sk-ant-). Usage runs on your own account, and SlyOS stores the key only on your phone — never shared.

Feed it your history

Optional, but it's what makes the brain actually you. Export your chats from each app, then load them in the setup wizard — or anytime under Brain → About (chats) and Now → Reconnect (LinkedIn).

WhatsApp

Open a chat → ⋮ menu → More → Export chat → Without media. Share the .txt to your phone. Repeat per chat.

LinkedIn

linkedin.com → Settings → Data privacy → Get a copy of your data → tick Connections & Messages. They email a .zip.

Instagram

App or web → Accounts Center → Your information and permissions → Download your information → choose Messages, format JSON.

Telegram

Telegram DesktopSettings → Advanced → Export Telegram data → format Machine-readable JSON.

Messenger / Facebook

facebook.com → Settings → Your information → Download your informationMessages, format JSON.

SMS & the rest

Incoming texts and any app with a reply box are learned live as you use SlyOS — no export needed.

Drop the exported files on your phone (the requested .zip/.txt/.json), then pick them in setup → "Bring in your data". SlyOS detects each format, imports the messages, and learns your writing voice from them.
