Pick a tool
Three tools help you understand how AI really works; three help you use it well at work. Everything runs locally in your browser.
Confusion Matrix Calculator
“Read a model’s confusion matrix the way a manager reads a P&L.” Enter the four numbers from any model evaluation — or a vendor’s claim — and see what the model is actually good at, in plain language.

Tip: precision answers “when it raises a flag, how often is it right?” — recall answers “of all the real cases, how many did it catch?”. A vendor quoting only accuracy is telling you the least interesting number.
The Six Questions
Answer six questions about your problem and get a recommendation: rules, machine learning, generative AI — or no AI at all. Matching the problem to the tool is where most projects are won or lost.
AI Project ROI Calculator
A back-of-the-envelope sanity check before anyone says “yes” in a meeting. Enter what the project costs and what it realistically saves — the calculator does the payback math and flags the classic failure patterns.
“Loaded cost” = salary + benefits + overhead, typically 1.25–1.4× gross salary. Adoption rate = share of eligible work that actually goes through the tool.
AI Myths Quiz
Ten statements you’ll hear in meetings, headlines, and sales pitches. Which are myths and which are facts? Each answer comes with the short version of why.
Spot the Bias
Six real-world scenarios — some famous, some painfully common. Name the bias before it names you. These are the traps that quietly break AI systems long before the algorithm gets a chance to.
GenAI Delegation Checklist
Treat a generative AI assistant like a bright, tireless, occasionally overconfident new intern: delegate freely, verify always. Run this checklist before you hit send on any AI-assisted work.
