Sentient OS
On-device intelligence layer for your entire digital life
Last verified:
What is Sentient OS?
Sentient OS is an on-device intelligence layer for your entire digital life. It runs a custom-built vision LLM on your own phone or computer while the device charges overnight, so it can privately understand everything you have saved.
The product is centered on making your device “sentient” enough to search, connect, and reason across screenshots, notes, files, audio, bookmarks, and your screen. It is designed to let you talk to your data by holding down one button, and it can also connect through MCP so an LLM can interact with your data more directly.
A major feature is its knowledge graph, which organizes saved information into tappable bubbles so important items are easier to rediscover instead of being buried in lots of files and screenshots. It also includes ambient intelligence, which is meant to notice important things and remind you at the right time across devices.
The website positions Sentient OS as private by design because it runs on your own devices rather than in the cloud. It is aimed at people who want a personal AI layer that understands context across their digital life, and it is described as coming to both phone and PC.

Frequently asked questions about Sentient OS
What is Sentient OS?
Sentient OS is an on-device intelligence layer for your entire digital life. It is built to privately understand what you have saved across your phone or computer, including screenshots, notes, files, audio, bookmarks, and screen content.
How does it work?
The website says a custom-built vision LLM runs on your own phone or computer while the device charges overnight. The system is meant to process your personal data locally so it can learn context without sending everything to the cloud.
What can I ask it?
The page gives examples like asking what wine you liked or who you wanted to meet next week. It is meant to let you talk to your saved data and retrieve meaningful context from your own digital life.
What is the knowledge graph for?
The knowledge graph is used to organize your digital life so important information is easier to find later. The site describes it as a way to tap into bubbles and rediscover useful knowledge instead of losing it in thousands of screenshots, notes, and files.
What does ambient intelligence do?
Ambient intelligence is described as the AI looking out for you across devices. If it finds something truly worth reminding you about, it is supposed to surface that reminder at the right time.
Does Sentient OS work with MCP?
Yes. The website says that with MCP, you can let your LLM talk to your data too, which suggests a more direct connection between the assistant and your stored information.
Which devices does it support?
The site says Sentient OS is coming to your phone and PC. It also specifically mentions running on your own phone or computer while they charge overnight.
Why is it local instead of cloud-based?
The site says you cannot run AI over your entire digital life in the cloud because of privacy and cost. That is why Sentient OS is designed to run on your own devices in private.
What makes the system fast enough on-device?
The website highlights several optimization layers, including proprietary KV cache reuse and flash attention, a vision transplant from a larger model, modifications to Apple's MLX for batch multimodal inference, custom quantization, and device-aware RAM optimization.
Is pricing available?
No pricing information is shown on the website. The page does not list a free tier, a paid plan, or any subscription details.
