Tools
Working tools I built because I wanted the answer myself. Free and no sign-up. Each one does its calculations in your browser, not on a server. The site uses Google Analytics to see how the tools are used, including which options people pick.
Take a metric you measure, enter your number, and see where it sits against the published benchmarks that can actually speak to it — each source read separately, never averaged into one industry figure.
Answer a few questions about a product and see which kinds of EdTech it's closest to, and what that means for the PM job.
More will appear here as I build them. I would rather ship one useful tool than list six that do not exist yet.
