Synheart's infrastructure is live. On-device inference is free, forever.
Our Story
Synheart builds the Human State Interface (HSI), infrastructure that reads physiological and behavioral signals on-device and turns them into a real-time read on focus, stress, and recovery. We started here because we kept running into the same gap, over and over, in every product we used.
WHERE THIS STARTED
You’re deep in something that matters, and your phone buzzes anyway. Not because anything urgent happened. Because the app has no idea you were focused in the first place. Ten minutes later, three more notifications land back to back, right when you’re already stretched thin, and it feels like everything wants something from you at once.
A wellness app asks how you’re feeling today. You don’t know how to answer that in a dropdown. Some days you’re sharp. Some days you’re running on nothing. That’s not a mood you can log once a day, it’s a spectrum that moves by the hour, and every piece of software you use treats it like a switch instead.
None of this is a UX problem. It’s an information problem. These systems are optimizing for what you clicked, typed, or scrolled, because that’s the only signal they’ve ever had access to. They have no read on the person behind the input, so they guess, and the guess is usually wrong at the exact moment it matters most.
That gap is where Synheart started. Not “let’s build another wellness app,” but a narrower, harder question: what if focus, stress, and recovery were signals software could actually read, the same way it reads a click or a location? Not a survey. Not a mood log. A live, on-device read on human state that any product could build on.
We’re not building an app that tells you how you feel. We’re building the layer underneath, so the apps you already use can finally tell the difference between a good moment to interrupt you and a terrible one.
WHAT WE BELIEVE
Human state is some of the most sensitive data there is. It should never leave the device it was read on.
People are bad at rating themselves in real time. Physiological and behavioral signals tell a truer, more immediate story than a survey ever will.
We’re not chasing one killer app. We’re building the layer other builders stand on, the same way Stripe became the layer under payments.
We publish research, specifications, and datasets. Infrastructure this foundational has to be inspectable, not taken on faith.
Our Vision
A future where technology understands human state, not just commands, and adapts with intelligence and respect. AI systems that respond to how people focus, function, and recover, creating experiences that are more humane, personal, and trustworthy. Human state should be a native computing primitive, on par with time, location, and interaction.
Our Mission
To build the foundational infrastructure for human-aware AI. We transform physiological and behavioral signals into meaningful, privacy-first intelligence, so developers and researchers can build adaptive systems that align with real human needs. By uniting neuroscience, biosignal research, and machine learning, we help technology adapt to people, instead of the other way around.

We create infrastructure for human-aware AI, transforming signals into privacy-first intelligence. This helps developers build adaptive systems that meet real human needs.
THE PERSON BEHIND THIS
Israel founded Synheart in late 2025 on a single conviction: that software understanding human state is an infrastructure problem, not a product problem.
Modern systems understand what users do, but not how users function. We kept building features on top of that blind spot instead of fixing it. Synheart is what happens when you fix it first.

The same human-state stack powers all of it, from the developer SDK to the apps people open every day.
