Yantrahः
A yantra is any crafted instrument that harnesses force. Yantrah is the companion for the people who craft them — the ones who draw the mighty ship, the flying machine, and the motor vehicle before the world ever sees them.
It sits between a designer's first sketch and the class drawings that certify it — fast enough to iterate with, honest about its limits. The name is Sanskrit for instrument, tool or machine; the final visarga (ः) is the released breath that turns the word into an engine.
Concept explanations grounded in the Yantrah design course — naval, aeronautical, automotive. No sign-in, no AI calls, no charge.
AI-grounded calculations — resistance, power, weight, stability and compliance screening at concept stage.
Layer 1–2 coverage (concept estimation and parametric pre-design) is live in testing. Layers 3–5 on the roadmap: structural screener, production planning, outfitting.
Concept-stage guidance only. Not for final design, construction, material ordering, or class submission. Confirm all results with a competent engineer before relying on them.
