"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."
"I run my numbers through Zing² before I order wire. It’s a second pair of eyes that doesn't get tired."

FREQUENTLY ASKED
Is this based on the latest NEC?
Can I trust the code interpretations?
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.
