Pricing FAQ
How is the yearly price set?
Yearly = monthly × 10 — two months free compared to paying monthly.
What exactly does Perpetual include?
Perpetual licenses cover the desktop app only and include 1 year of updates. After that the license keeps working forever; staying current is an optional update subscription at 20% of the perpetual price per year.
What counts against the AI cap?
Only AI-assisted operations (e.g. AI model suggestions and review assistance). Structural analysis and code checks run locally in WebAssembly and never count against any cap.
Can I try before paying?
Yes — the Free plan has no time limit and runs in the browser after you sign in with your email (up to 15 nodes, watermarked; no payment details). Evaluate whether the structure solves and the results are right on screen; a subscription unlocks unlimited nodes and full export.
