Warn, never certify
No "Safe." No green all-clear. We surface risk and context so you can decide — we never give false confidence.
The team
A guardian that's
A guardian that's
honest with you.
Sentinel comes out of Gigai Kripa Services — a software studio that ships web, mobile, AI and game products. We built Sentinel because online safety is full of false promises, and we wanted the opposite: a calm guard that tells you the truth.
Why we made it
Scams got smarter. Safety tools got louder.
Modern scams are AI-generated, pixel-perfect, and span email, SMS, calls and the web. Most "security" tools answer with noise, fear, and "100% safe" badges that simply aren't true. We wanted a guardian that does the technical checks a person can't — quietly — and is honest about exactly where it can and can't help.
When Chrome shipped on-device Gemini Nano, it became possible to read a page's intent and warn you without sending a single byte about your browsing anywhere. That constraint — everything local, data flows in only — shaped every line of Sentinel.
What we build by
Three principles
On-device only
All AI runs locally. No AI network calls, no "is this safe?" lookups. Data flows in only — never out.
You stay in control
Silent by default; it speaks only when it matters. Every warning offers a clear choice — never a hard block.
The maker
One studio, one accountable team
