NavJun vs ChatGPT
The standards that decide whether your product passes are sold, not published. ChatGPT has almost certainly never read them. It answers from summaries. NavJun answers from the licensed documents, and cites the clause.

WHEN TO PICK WHICH
ChatGPT is the right tool if…
→ You're scoping, not deciding. You want a rough sense of which directives and standards are in play before anyone commits budget.
→ You're drafting, not citing. Summarising a directive for an internal deck, or turning your own notes into something readable.
→ The question isn't really regulatory. A test plan template, a supplier email, a block of firmware. ChatGPT is good at all of it.
→ You already own the standards and know them well. You want somewhere to think out loud, and you'll catch an error yourself.
You should choose NavJun if…
→ A wrong answer costs real money. One failed test campaign or customs hold is worth more than years of any subscription.
→ You need to show your work. Every answer names the clause it came from, so a reviewer can check it instead of trusting it.
→ You work in hardware or electronics specifically. NavJun is built on 8 years of Your Main Guy consulting in lighting, electrical, IoT, and electronics.
→ Editions and amendments matter. Quoting the superseded revision of a standard is the expensive kind of wrong.
SCENARIO
A Vancouver-based team is designing a connected commercial lighting controller. They're planning to sell in the EU (CE + EU CRA), US (FCC Part 15, UL listing through a lab partner), and eventually the UK (UKCA).
With ChatGPT
Their engineer asks ChatGPT whether the EU Cyber Resilience Act applies to a connected lighting controller shipping in Q4 2026. It answers in seconds, fluently, and offers an article reference.
Then the checking starts. Is that the right article? Is that revision still current? ChatGPT can't show which document the sentence came from, because it never had access to the document. Verifying the answer takes longer than the answer saved. And if nobody checks, the error ships with the product.
With NavJun
The same engineer opens a chat, types “Does the EU Cyber Resilience Act apply to a connected lighting controller shipping to EU in Q4 2026?”, and gets a cited answer referencing Article 3 of Regulation (EU) 2024/2847 with the reasoning.
Follow-up: “And FCC Part 15 for the US version?” Same dialogue, same window. Where the licensed text doesn't settle the question, NavJun says so rather than filling the gap.
Both answer in seconds. The difference is how long it takes to find out whether the answer was right.
BEING HONEST
Everything outside compliance
ChatGPT writes code, summarises meetings, drafts emails and plans your week. NavJun does one thing. If you want a single tool for all of it, this isn't that tool.
Drafting and rewriting
Turning rough notes into clean prose, or rewriting the same paragraph five ways, is something ChatGPT does better than any specialist tool.
Open-ended thinking
Questions with no authoritative source to cite, like naming a product or sketching an architecture, play to ChatGPT's strengths rather than NavJun's.
Costing next to nothing
ChatGPT is free on its basic tier and already open in another tab. NavJun costs more because licensing the standards costs more.
Keep using ChatGPT for those. Use NavJun for the answers you would have to defend.
