What It Is

CHIEF — AI Crew Chief by Walker Sports is an AI race assistant for real-world motorsport and sim racing. Its core pitch is that it “remembers every setup change, lap time, and driver impression, then tells you what to do next to go faster.” The product is split into Race Chief and Sim Chief: the former is for real-world racing, while the latter supports sim platforms such as iRacing, Assetto Corsa, rFactor 2, AMS2, GT7, and F1 games.

Core Features

Its AI capabilities center on voice Q&A and long-term memory. Users can press the microphone button to ask about historical setups, tire pressure and camber adjustments under changing track temperatures, or how to gain a tenth of a second in a particular corner. Sim Chief can automatically capture iRacing sessions, including car, track, lap times, fuel usage, weather, steering wheel/pedal settings, and more. Race Chief provides complete setup sheets, maintenance logs, and reminders for different types of cars. The page also mentions screenshot analysis, an iRating growth mode, Coach Dave setup file integration, and API access for the Elite plan.

Pricing and Trial

The pricing information is noticeably inconsistent. The top of the page mentions a 30-day free trial and lists monthly pricing for Sim Chief at $3/$7/$12 and Race Chief at $5/$10/$20. Later on, it says all plans include a 7-day free trial, with Starter at $19/month, Pro at $39/month, and Elite at $79/month. The FAQ clearly states that a card is required for the trial, billing starts after 7 days, and users can cancel at any time. In practice, the checkout page should be treated as the source of truth for pricing.

Pros and Cons

The main advantage is that the product is highly focused on a specific use case, making it suitable for structuring and preserving racing setup knowledge over time. It also provides privacy-related details such as TLS 1.3, row-level data isolation, and JSON export. The downsides are that it does not disclose the underlying AI model, accuracy, or validation methodology; video analysis is still marked as coming soon; API access is limited to the Elite plan and lacks detail; and there is no information about a Chinese interface, Chinese voice support, or supported payment methods.

Who It’s For and Access from China

CHIEF is better suited to serious sim racers, real-world drivers, small racing teams, and users who need to review setup history over the long term. It is less suitable for players who only drive casually for entertainment. Access from China is unclear, as the page does not mention mainland network availability, RMB pricing, or local payment options. If access or payment is restricted, alternatives or complementary tools to consider include MoTeC, Garage 61, VRS, Coach Dave Academy, and CrewChief.
