YOU BUILD IT.

WE DOUBLE-CHECK IT.

Inspectors don't care about intentions; they care about the code. A simple calculation slip can cost you thousands in labor and delays.

Zing² is your pre-inspection filter. We don't replace your expertise—we back it up. We scan your inputs for code conflicts, sizing errors, and fill violations so you can fix them before the truck rolls.

  • Offline access to core calculators & NEC reference tables.
  • Results verified against official NEC book logic.
  • Instant Article & Table citations for every answer.
  • Visual Inspection photo analysis for on-site issues.STANDARD
  • Printable calculation reports for inspection prep.
“Caught a mistake I missed”

"I’ve been doing this for 20 years, but I still use Zing² to double-check my fill calcs. It’s like having a code expert in the passenger seat."

FREQUENTLY ASKED

Is this based on the latest NEC?

Currently, our AI is grounded in the National Electrical Code (NEC) 2020 edition.

Can I trust the code interpretations?

Zing² provides Inspector-Ready data based on NEC tables and engineering formulas. However, the final authority is always your local Inspector (AHJ). Zing² is a tool to help you defend your work with citations, not a legal guarantee of passage.

Why don't I just use ChatGPT or Gemini?

ChatGPT is a writer; Zing² is an auditor. ChatGPT will happily give you a wrong code section if it sounds "right." Zing² is different in three key ways:

  • Math-Locked Accuracy:LLMs often "guess" numbers based on patterns. Zing² routes all technical queries to our built-in engineering tools for mathematical certainty.
  • Hard-Coded Citations:We use RAG to anchor answers in the actual NEC. If we can't cite the specific Code Article, we won't give you an answer.
  • Inspector-Ready:We don't just give you a number; we give you the math and the citation to back it up under inspector scrutiny.
