Why it's not just another chatbot answer
Deterministic & cited
The same inputs always produce the same answer, each one traceable to NEC 310.16, Ch.9 Table 8, 240.6, or ABYC E-11. Auditable, not a guess.
A document people accept
Inspectors and insurers get a formatted report with a one-line diagram and sign-off blocks — not a chat transcript.
Honest by design
Not a P.Eng stamp, and it says so. Built to aid your installer, surveyor, and underwriter — with the disclaimer on every page.
Free to start. $29/mo to remove the watermark.
NEC + ABYC today. Van builds, off-grid cabins, sailboat refits.
Common questions
Is this a P.Eng / PE stamp?
No — it's design documentation generated from your input and published codes. It doesn't replace a stamp where one is required. Verify with a licensed professional before installation.
What codes are supported?
NEC 690/706/710 and ABYC E-11 today. ISO 13297 and AS/NZS 3001 are on the roadmap.
Can I use it for insurance or an AHJ?
It produces the kind of documentation that aids their review. Final approval rests with the AHJ or carrier.
