Why these tools exist
The business calculators each came out of a question a client asked during an engagement, usually early and usually before there was a budget to answer it properly. What would this actually save? What will it cost to run at our volume? Are we even ready to attempt it? Which model should we use? Where would we start?
The career tools came from the other direction. Reading what internship applicants wrote about themselves, the same problems appeared over and over: a CV that would not survive an automated filter, no idea what an interview for the target role would actually ask, and a plan that was a list of courses rather than a sequence of things built.
Rather than answer each one from scratch, we built the work into something anyone can use. They are free and require no sign-up.
Each tool shows its working
Every tool page states how it reaches its answer, what it assumes, and how to read the result without over-trusting it. That is unusual for this kind of tool and it is deliberate: one that will not show its arithmetic is worth less than one that does, because you cannot tell whether its assumptions match your situation.
The assumptions are the part worth reading. The AI ROI calculator, for example, depends almost entirely on what share of the work you believe AI can absorb — and that single number, set optimistically, is how most AI business cases end up wrong.
The career tools state their limits on the page rather than in a footer. None of them invent experience, numbers or employers you did not give them, and none can tell you whether you will get the job.
Where to start
If you are applying for work: run your CV through the resume analyser first, then the ATS checker against a specific job description. Those two together fix the problem that stops most applications before a person reads them. The interview generators are worth running once you have an interview booked rather than before.
If you are planning an AI programme: if you do not yet know what to build, the use-case finder suggests candidates from the shape of your work. If you know what to build but not whether it is worth it, use the ROI calculator. If you have decided and need to budget, the LLM cost calculator will get you a monthly run rate. If you are wondering whether your organisation can support any of it, the readiness score is the honest place to begin — and its most common answer is that data access, not modelling capability, is the constraint.
