Isochron AI

Isochron AI turns a phone video into a measurement with an honest error bar. Film a pendulum, a bouncing ball or anything that oscillates: Muse Spark looks at the video, finds the moving object and the moment it is released, and flags what could go wrong; SAM 3.1 tracks it with a mask on every frame; tested code fits competing models with propagated uncertainties; and a Muse Spark agent runs the scientific loop, registering falsifiable predictions before an experiment exists and verifying them blind. On five real pendulum runs, two blind predictions were confirmed and two came out in tension the same way; the instrument traced the miss to the human's tape measure, not to its own timing, and Muse Spark had flagged the hidden string attachment before any number existed. Everything is open source (MIT), reproducible without an API key, tested in CI (75 tests), and runs as a web app, a static site and a Docker image.
