Swipe to see Praevisio in action — from import to prediction to side-by-side decisions.
Load your data, pick the outcome you care about — sales, price, score, anything you can measure — and Praevisio shows you which factors are most associated with it, explained in plain language instead of statistics jargon. Built for people who make decisions, not for statisticians.
Load a CSV and explore your data with instant summaries and charts.
Choose the outcome you want to understand or predict.
See the factors most strongly related to that outcome, ranked by strength.
Get a simple model that shows which factors matter most — and how confident to be in each.
Compare options side by side to weigh real choices, with the uncertainty shown honestly.
Many tools hand you a confident-looking number and stop there. Praevisio is different. It shows uncertainty plainly, separates strong signals from noise, and reminds you that patterns in past data are associations — not proven causes. It's made to help you decide where to look and what to test, not to oversell certainty it doesn't have.
Everything runs on your device. Your data never leaves your iPhone, is never uploaded, and is never collected. No account. No tracking. No ads.
If you can open a spreadsheet, you can use Praevisio. It chooses sensible defaults, handles messy real-world data, and explains every result in everyday language.
Small business owners, managers, analysts, students, researchers — anyone curious about what's really driving the numbers in their data.
Praevisio is a tool for exploring and understanding data. It is not a substitute for professional statistical, financial, or legal advice.
