Every answer is generated only from the actual code text we've ingested, no hallucinations from general training data. Each requirement is followed by a cited [Source: …, Page X] tag that links directly to the page in the source PDF. You can verify the underlying clause in two clicks. We also use a cross-encoder reranker to surface the best-matching passage before the LLM ever sees the question.
No. CodesWise is a reference tool, it accelerates code research and citation lookup, the way Westlaw accelerates case-law research for lawyers. It doesn't replace a licensed professional's judgment, project-specific design decisions, or the act of stamping. Always verify against the published source before relying on a clause for compliance.
The 2025 National Building Code, National Fire Code, National Plumbing Code, and National Energy Code for Buildings, plus the 2020 editions where provinces still enforce them. Provincial and municipal overlays loaded: Ontario Building Code 2024, BC Building Code 2024, BC Fire Code, Vancouver Building By-law 2025 (Vol 1 + Vol 2 + Plumbing), NBC Alberta Edition 2023, NFC Alberta, and Code de construction du Québec. We also ingest referenced standards (CSA, ASHRAE, NFPA, ULC) and engineering handbooks (CISC, CAC, Wood Design Manual) to support deeper queries.
When you set your province in your account, CodesWise scopes answers to the code that province actually enforces. If a provincial overlay isn't loaded yet, the system falls back to the National edition the province bases its code on (e.g. NBC 2020 for Manitoba), and tells you what's missing. You can also widen the search to all available codes from the chat header at any time.
Yes. The application and all conversation data are hosted in Canadian regions. Queries are not stored for model training and are not shared with third parties. We process queries through Anthropic's Claude API; that processing is governed by Anthropic's enterprise privacy terms and is logged only for operational debugging.
24 hours of full access, no credit card required, one trial per email. You get the same retrieval, citations, and PDF page-locate as a paying user. After the trial you can pick a plan or walk away, no charge happens unless you actively subscribe.
Yes. Subscriptions are month-to-month (or annual at a discount). Cancel from your account page; access continues until the end of the period you've already paid for, then stops. No retention friction, no "talk to sales to cancel" calls.
We ingest new model editions as soon as the NRC publishes them, NBC 2025 was indexed shortly after its December 2025 release. Pro and Enterprise users get early access to new editions. We also track adoption status across every province so the system serves the edition your AHJ actually enforces, not just the latest one.
It happens, AI can mis-rank a clause. Every citation links straight to the source PDF page so you can verify in seconds. There's also a thumbs-down button on every answer that flags it for review; we monitor downvotes weekly and tune retrieval. If you spot something wrong, the feedback loop is one click, and the source link makes verification fast either way.
ChatGPT was trained on web-scraped text, not the actual published National Building Code, NPC, NFC, NECB, or any provincial code. When you ask ChatGPT a code question, it generates an answer that sounds plausible based on similar-looking sentences it has seen, then invents a section reference. CodesWise retrieves directly from the actual code PDFs and cites the exact page and section. We wrote a side-by-side comparison with a real worked example: CodesWise vs ChatGPT for Canadian Building Code questions →
The official codes remain Crown Copyright (NRC) or provincial property. CodesWise summarizes and indexes content for reference assistance, we don't redistribute the codes themselves. The product points users back to the official published source for any decision that requires the canonical text. Active discussions with NRC on a formal commercial licensing arrangement are in progress.
