Palm Ark

Modernization, you can trust.

The world's first AI modernization engine. Every rule your business depends on, extracted deterministically and carried across — with full source lineage.

Generic AI guesses. Palm Ark is grounded in your actual code — every rule it carries is traceable to the line it came from.

The crossing

The storm takes the platform.
Everything that matters survives.

Grounded in
your reality.

Every output is rooted in your real code, not in assumptions. No hallucinated logic, no invented rules — only what your system actually does.

Always the right
intelligence.

Ark adapts to the best model for each job, without ever locking you into one. The intelligence changes; your control doesn't.

Accuracy,
without guesswork.

Around 95% extraction accuracy with full source lineage — against roughly 30% from a generic LLM asked the same question.

More inside

Built for the systems others can't touch.

Predictability, built inEvery result is consistent and repeatable — the same input gives the same answer, every time.
Your code stays yoursArk runs where your code lives. Nothing leaves your perimeter.
Built for what others can't handleDesigned for the complexity of large, regulated legacy estates.
50,000+ lines, one passA single deterministic pass holds tens of thousands of lines of context at once.

One waveform. Four frequencies.

Ark reads what Key has mapped, and hands clean, traceable logic to Ray.
