Tool questions
Yes — every tool on this page is completely free, with no signup, no email gate and no usage cap. They run entirely in your browser, so we have no cost to pass on. They're lead magnets: useful enough that some people who try them end up hiring us to run the work for real.
No. Every tool is 100% client-side — the calculations happen in your browser with plain JavaScript, and nothing you type is uploaded, stored or logged. There's no backend and no third-party tracking on the inputs. Close the tab and your data is gone.
They use the same formulas we use internally, so they're solid for planning and sanity-checks. But they're only as good as the inputs you give them, and ad platforms, analytics and statistical tests have their own quirks. Treat the output as directional, and validate against your source of truth before you bet real budget. Want it done properly? That's our day job.
