Purple Sector

What it does

Purple Sector connects your AI assistant to Assetto Corsa / Assetto Corsa Competizione telemetry data, turning raw lap times and sensor readings into actionable coaching insights. Drivers can ask natural-language questions about their performance and receive intelligent suggestions backed by live telemetry streams.

Tools

• telemetry_capture — Ingest real-time UDP telemetry from Assetto Corsa and store lap data in the local database
• lap_analysis — Run AI-powered analysis on a specific lap or compare multiple laps to identify braking, throttle, and cornering inefficiencies
• coaching_suggestions — Generate prioritised improvement recommendations based on sector time deltas and telemetry signatures
• lap_list — Retrieve stored laps for a session, track, or car combination
• telemetry_stream — Subscribe to live telemetry feed during an active session
