Grafiti Unveils SigmaStat V1: AI-Guided Statistics, Fully On Your Device

SigmaStat V1 pairs guided statistical analysis with ARAI, an on-device AI assistant — no cloud, no data leaving your machine, no guesswork about which test to run

PALO ALTO, Calif. — Grafiti LLC today launched SigmaStat V1, a statistical analysis platform that does something most tools don't: it tells you not just how to run a test, but whether you should be running it at all.
SigmaStat combines guided statistical workflows, regression and predictive modeling, and publication-ready 2D/3D graphing in one platform. The headline addition in V1 is ARAI — an AI assistant built into SigmaStat that runs entirely on-device. No cloud round-trip, no external servers, no data leaving the researcher's machine.
The platform is built for the entire spectrum of statistics users — from engineers running discrete dependent variable regression to undergraduates figuring out which test applies to their dataset for the first time.
“Grafiti has always existed to serve the scientific community — to take the guesswork out of statistics for people who aren't statisticians,” said Shirish Tangirala, Chief Operating Officer of Grafiti. “SigmaStat V1 is the first time we've brought AI into our products, and we built it on-device on purpose: your research data is yours, full stop.”
“We were just as deliberate about what ARAI actually does,” Tangirala said. “AI is built for understanding language, context, and intent — so we use it to guide people to the right statistical test and explain why it applies. We don't use AI to do the statistics. That still runs on real, validated statistical methods, the way it should. ARAI is the guide, not the engine — and that's exactly what AI is supposed to be good at.”
