Pass the PE Power exam.
15 minutes at a time.
GridGuardian is an agentic AI tutor that diagnoses exactly why you're getting questions wrong — Conceptual gap or Calculation error — and builds a personalized study plan grounded in verifiable NCEES references. No hallucinations. No guesswork.
The PE Power exam has a 40–50% first-attempt fail rate.
Existing prep tools don't know why.
Traditional study books give you questions and answers. They can't tell you whether you failed because you had the wrong mental model (Conceptual) or made an arithmetic error (Calculation). Those require completely different remediation — and no flashcard app can diagnose the difference.
GridGuardian reads your free-form reasoning, classifies your exact error type, and routes you to the right drill. It's the difference between a study book and a private tutor who actually understands engineering.
The grid is getting more complex.
PE Power engineers are in higher demand than ever.
US grid modernization is adding 500GW+ of renewable capacity by 2035 — requiring thousands of new PE-licensed engineers.
PE Power exam difficulty increased in 2024 with new topics on power electronics and distributed generation.
70,000–100,000 engineers are in the PE Power candidate pipeline. Only 55% pass on the first attempt.
Utility companies are now sponsoring PE prep as a retention benefit — creating an institutional market.
Built for engineers who want to pass, not just practice
Every feature maps to a specific failure mode in traditional PE exam prep.
15-Minute Sprint Engine
Time-boxed micro-study sessions that fit into any schedule. Soft warning at 15 min, hard submit at 30. Proven to improve retention vs. marathon sessions.
Misconception Diagnosis
The AI reads your free-form reasoning and classifies your error as Conceptual (wrong mental model) or Calculation (right idea, wrong math). Most study tools can't do this.
Citation-First Evidence Gate
Every AI explanation is grounded in verifiable NCEES references. If a source can't be verified, it's labeled 'Unverified'. Zero fabricated citations — ever.
Adaptive Mastery Engine
Your Exam Readiness Score updates after every answer. The engine identifies your highest-value knowledge gaps and routes the next sprint to close them first.
Safety & Integrity Guardrails
The system refuses real-world engineering design questions with 95%+ precision. You're here to pass an exam, not get liability-laden advice.
HHH Metrics Dashboard
Track your Helpful (sprint completion), Honest (citation fidelity), and Harmless (safety pass rate) scores — the same framework used to evaluate the AI itself.
8 steps. Every sprint. Fully automated.
This is the full agentic pipeline that runs behind every 15-minute study session.

From the engineers who passed
Real results from engineers who used GridGuardian to close their specific knowledge gaps.
"I failed the PE Power exam twice with traditional study methods. GridGuardian diagnosed that my problem was Per-Unit System calculations — not conceptual gaps. Passed on my third attempt with 3 weeks of targeted sprints."
"The citation-grounded answers are a game changer. Every explanation references the exact NCEES section. I stopped second-guessing whether the AI was making things up — it always shows its work."
"15-minute sprints fit perfectly into my lunch break. The misconception diagnosis told me I was confusing RMS and peak values in three-phase calculations — something no textbook would have caught."
"The safety guardrails actually impressed me. I tried asking a real-world arc flash design question and it politely redirected me to the NFPA 70E exam topic instead. Exactly the right behavior for an exam prep tool."
