Built because the analysis was never to hand.
A free AI analyst for bottlenecks and throughput, for anyone who needs a trustworthy number and a clear next move without rebuilding a spreadsheet.
BottleneckCalc started as a maintained side project by an industrial engineer who got tired of re-deriving the same formulas in a fresh spreadsheet every time a line slowed down — and then still having to interpret the result by hand. The theory of constraints is simple; having an analyst on call at the right moment never was.
So this is that analyst: the handful of calculations operations and process people actually use, wired to an AI that reads the result and tells you what to do about it. No login wall, no upload, no eighty-row template — just the number, the gauge, and a plain recommendation. Everything runs in your browser, because the quickest analyst is the one with nothing in the way.
Put a trustworthy AI analyst for throughput one click away — free, fast, and clear enough that the answer always comes with its meaning and its fix.
