Purple Sector is an in-browser motorsport telemetry analysis service for racing drivers, track-day drivers and engineers. It helps users understand where lap time is gained or lost by comparing laps corner by corner, viewing speed and GPS data, and reviewing consistency and video synchronisation. Drivers can upload recordings from a wide range of sources, including Racelogic VBOX, AiM, MyChron, MoTeC, RaceBox, Garmin, SpeedAngle, Alfano, RaceChrono, TrackAddict and Harry’s LapTimer, as well as GPX, NMEA, CSV, TSV and TXT files.

The browser-based workspace identifies laps and corners and highlights measured differences between laps. Purple Sector’s AI Coach can rank time-costing corners and suggest a specific focus for the next session when the recorded data supports it; it avoids recommendations that the telemetry cannot substantiate. Analysis tools are free, with a free account that includes one AI debrief and cloud storage.

Paid monthly or annual Coach subscriptions add recurring debrief credits and more storage, while one-time credit packs are also available
