iRacing About PitDelta
PitDelta is deliberately narrow. There is no trace viewer and no way to look at the telemetry itself: you upload a session and get back prose, a ranked list of corners with the time each one costs and a specific change to make in each. That is what separates it from the telemetry tools elsewhere in this directory, where the whole point is to read the data yourself. If you already get value out of a trace, this is not aimed at you; if you never have, it is.
The more unusual part is what it declines to say. Practice assignments are computed from telemetry by fixed rules and withheld when the evidence is too weak to support them, so a short or scrappy session returns a note saying the signal was too small rather than confident-sounding advice. It also looks for a tendency that repeats across clean laps instead of treating every difference between two laps as a lesson, on the reasoning that one habit usually costs time in several corners at once. The only AI-written element is a single summarising remark, and raw telemetry is not sent to a language model.
One thing worth knowing before picking the free tier: it is free partly because the reports double as product examples, so a debrief card from it may appear anonymously in the vendor's own marketing with track and car names removed. Reports from paid plans are private. Note also that there is nothing here to start alongside a sim. PitDelta runs in a browser after the session is over, not as a companion process during it, so it sits outside what a SimLauncher profile launches.
