Pick the one that matches your week

Six things, each built from work we have actually done for New Zealand businesses.

The two quizzes take about a minute each and nothing is pre-selected for you. The calculator gives you a number to take to a meeting. The three hubs show the jobs AI is already doing, in plain words, with the catches named.

5-question quiz

Which Claude plan do you need?

Anthropic prices everything in US dollars, so it is hard to tell what you are really paying. Five questions, about a minute, and you get the plan that fits in New Zealand dollars with GST included, plus the thing to watch out for.

The four levels of AI use

Most businesses can say they are using AI but not whether they are using it well. Five questions place where you actually sit, from asking it questions to running work on a schedule, and give you the one next step.

Calculator

AI cost calculator

Put in how many people do a task, how much of their time it takes and what they earn. It works out what that task costs you a year, what it would cost with AI doing most of it, and the difference. No email, no sign-up.
