Desert Sky AI is a software company with a singular focus: building the tools that give seniors independence, security, and control — for as long as possible.
Seniors are the most experienced, most capable — and most underserved — technology users on the planet. We're here to change that, one product at a time.
Every product we ship is designed around how seniors actually use technology — not how engineers assume they do. Clarity, dignity, and control are non-negotiable.
Scams, fraud, and digital manipulation cost seniors billions every year. Our software puts active, intelligent protection in the hands of the people who need it most.
Independence isn't about avoiding help — it's about having the tools to make your own informed decisions. We build the tech that makes that possible.
Keel is our flagship mobile application: forward a suspicious email, snap a photo of a text or letter, or upload a voicemail, and Keel checks it and explains the verdict in plain English, not tech jargon.
Built specifically for seniors, Keel is a trusted second opinion against the fraud epidemic that costs American seniors $3 billion every year.
🍎 TestFlight: install the free TestFlight app from the App Store first, then tap the button above — it'll open TestFlight and prompt you to install Keel. No separate email invite needed.
▶ Android: tapping the button downloads an APK file directly. Your phone will warn you about installing from an unknown source — that's expected for a preview build, not a sign anything's wrong. You'll likely need to tap "install anyway" or similar 2–3 times before it lets you proceed.
Keel is just the beginning. Our roadmap addresses the full spectrum of senior independence — from financial protection to health navigation to staying connected.
AI-powered scam detection for calls, texts, emails, and links. Available now on iOS and Android.
A watchdog layer for bank and investment accounts that flags suspicious patterns before losses occur.
AI-assisted guidance through Medicare, prescriptions, and care decisions — in plain language, at your own pace.
A respectful, consent-first platform that helps seniors and their families stay coordinated without sacrificing autonomy.
Most technology is built by 25-year-olds for 25-year-olds. We build differently — with seniors at the center of every decision.
Every feature starts with one question: does this make life better for a senior? If the answer isn't obviously yes, we don't build it.
Our interfaces use large text, plain language, and familiar patterns. Brilliant UX is invisible — users just feel capable and in control.
We never sell user data. Every product is built on a foundation of trust — because that's what our users have earned, and what they deserve.
We apply machine learning where it genuinely protects and empowers. Real-time scam detection is hard — that's exactly why we do it.
Desert Sky AI was founded by Bill Prentice, an Arizona-based technology entrepreneur who watched the senior community get left behind — and exploited — by the very technology that should be serving them.
The company's first product, Keel, was built in direct response to the scam epidemic targeting seniors. But the mission is broader: to build a full suite of software tools that give seniors the same power, access, and control that technology gives everyone else.
We're open to partnerships, advisory conversations, investor introductions, and development collaborations. Reach out — we'd love to talk.
