The Brain.

One answer. Three voices.

Your messages stay yours.

• SlyOS never trains a model on your messages, and never sells them.
• The AI is Anthropic’s, with OpenAI for search and as a backup. They get what a reply needs, under their own API terms.
• iMessage, SMS and WhatsApp are read on your own device, signed in as you. Their logins never reach us.
• Export everything, on any plan, at any time.

Real use, recounted every night.

Your inbox, inside the AI you already use.

Ask it what needs a reply, what someone said yesterday, or to tell someone you’re running late. It answers from every channel you connected. Part of every paid plan.

Invite a friend. In SlyOS, open Settings → Plan → Invite a friend and send them your link. When they sign up through it and pay for their first month, you both get a free boost on top of your plan, 14 days later.
