Waitlist open
A living model of who you are — captured from your work, applied to every AI you use, owned by you.
EnterProducts for human agency.
Sentinel is a focused software studio building products that restore trust, clarity, and human agency in daily life.
The thesis is simple: build great software for the people who genuinely need it, keep incentives clean, and ship products that make them more capable — not more captured.
