Engineering & AI Tools
Free calculators we built for problems we work on: simulation pipeline cost, LLM API pricing, and voice AI cost per call.
Built for engineering teams
Simulation Cost & Surrogate ROI Calculator
See what your CAE/CFD pipeline costs each year (compute, licenses, engineer time) and how quickly a surrogate model pays for itself.

Cost calculators for teams shipping LLM and voice products.
LLM Pricing Calculator
Compare API pricing across OpenAI, Anthropic, Google, Mistral, and more. Estimate self-hosting costs and find your break-even point.
Voice AI Cost Calculator
Estimate voice AI infrastructure costs per call. Compare STT, LLM, and TTS providers across orchestration and speech-to-speech workflows.
