How much does AirInduct Sim cost?
AirInduct Sim is free to start, and AirInduct Pro costs $239.99 a year (about $20 a month), $29.99 a month or $8.99 a week; the yearly and monthly plans start with a 3-day free trial. The free plan includes the Helmholtz coil topology, 3 simulations a month and 1 AI Copilot task a month, and returns the same outputs as Pro for that topology: mutual inductance, self-inductances, coupling coefficient k, induced voltage and peak magnetic field. AirInduct Pro unlocks all eight coil topologies — circular and square Helmholtz, circular and square DTC, and the four Helmholtz–DTC cross pairs — with unlimited simulations, the AI Copilot (300 tasks a month, up to 50 a day), 3D surface, heatmap and contour views, parameter sweeps, the optimizer, and PDF, KiCad, DXF and SPICE export. The weekly plan suits a short project, the monthly plan ongoing design work, and the yearly plan saves 33% against paying monthly. Prices are in US dollars and include any applicable tax; web payments are processed by Stripe.
