Corner Cue
A sim-racing coach that watches your onboard video, extracts real corner geometry, and tells you in seconds where you are losing time.
iRacing and ACC league drivers in C-class and up who can lap consistently but cannot tell why their teammate is faster
- onboard-video upload that returns corner-by-corner pace loss in tenths of a second
- annotated overlay showing your braking point and minimum speed versus a coach baseline
- per-track baseline trained on the open-source ForzaHorizon6 geometry-head physics model
- side-by-side replay comparison when you upload two laps of the same corner
ForzaHorizon6-VisionAI just open-sourced an 80-star, geometry-grounded racing vision net, giving sim-racing apps a public baseline that maps sightlines to physics for the first time.
Market already validated by at least five paid competitors (Track Titan, Coach Dave Delta, Trophi.ai, RaceCraft.ai, Full Grip Vision) all targeting the same C-class-and-up iRacing/ACC pain point.Best AI Sim Racing Coaches in 2026 — Complete Comparison ↗AI Simracing Coach for iRacing, ACC, AC, F1 and Forza | Track Titan ↗
The exact niche is saturated — Full Grip Vision, Trophi.ai, Track Titan, RaceCraft.ai and Coach Dave Delta already offer AI video/telemetry coaching for iRacing/ACC; the camera-based corner-geometry angle is incremental, not a new category.Full Grip Vision - AI-Powered Real-Time Voice Coaching for Sim Racing ↗Delta 6.0 - Setups, Telemetry & Video Analysis for Sim Racing ↗
Willingness to pay is proven: Coach Dave Delta charges $11.99/mo or $109/yr, Track Titan sells paid AI-insight tiers, and Trophi.ai/RaceCraft.ai run freemium models — users happily subscribe for AI coaching.Coach Dave Delta Subscription Pricing ↗Track Titan Pricing ↗
Sim racing is a durable, growing category (iRacing, ACC, LMU, F1 esports) and the pain point of league-level pace gaps is structural; however the open-source 'ForzaHorizon6-VisionAI' baseline sits at only 80 stars / 13 forks and targets an arcade open-world game, so the 'why now' tech trigger is weaker than pitched.ForzaHorizon6-VisionAI GitHub repo (80 stars, 13 forks) ↗
Hard build: a geometry-grounded vision net must be retrained or fine-tuned for iRacing/ACC tracks (the public baseline is Forza Horizon 6, not closed-loop sims), needs per-track/per-car datasets, and must beat incumbents that already use telemetry + HUD overlays — non-trivial CV/ML engineering.ForzaHorizon6-VisionAI README — game-internal study, not generalizable baseline ↗
