Over the last 20 years, the world traded ownership for convenience. We gave up privacy for more power. Piece by piece, we handed over our memories, our messages, even our thoughts to the cloud. Every search, every question, every idea became someone else’s data. Somewhere along the way, “smart” stopped meaning yours. Silo was built to take it back.
At Silo we believe the future of intelligence isn’t hosted; it’s owned. Your thoughts shouldn’t be someone else’s training data or business model. Your data shouldn’t be mined, profiled, or sold. Your device shouldn’t spy on you—it should serve you.
That's our starting point.
Silo is built on a simple idea: the AI you use should belong to you. It should live with you — on your device, in your control — not in a data center halfway across the world. Every memory, every conversation, every insight stays encrypted, private, and personal.
"Not your device. Not your data."
That's the contract most technology companies have made with you. We're rewriting it.
That's our promise.
When you use Silo, you’re not feeding a cloud; you’re training your own intelligence. A private system that learns what matters to you, not what sells. A memory that connects your world, not the world’s agenda.
You should be able to ask without being watched. Learn without being logged. Grow without being tracked. Silo exists because the most powerful AI in the world means nothing if it isn’t truly yours.
It’s time to reclaim your digital self: your thoughts, your history, your mind. Silo isn’t another cloud AI. It’s your intelligence. Owned, controlled, and protected by the only person who should ever have access to it—you.
Own yourself.
Your device. Your data.
Ask anything. Control everything.
