Yes — five questions a day with no account and no card. Link a free account and that rises to fifty, and answers start coming from your own uploaded plans instead of the Code alone.

Do I need to install anything?

No. It is a WhatsApp conversation with a business number. If you have WhatsApp, you already have everything you need.

Can I send a voice note instead of typing?

Yes. Voice notes are transcribed and answered the same way a typed question is, which is the point when you are on site with gloves on.

How do I know the answer is right?

Every answer names the National Construction Code clause it rests on, so you can check it rather than take it on faith. Answers also carry a note to confirm with your certifier for your specific project.

What makes a window compliant?7:42

Depends which requirement you're chasing — glazing, energy, fall protection or ventilation all bite on windows. If it's a bedroom above ground level, the one that usually catches people is the fall-protection limit on openable sashes.NCC 2022 · Vol 2 · clause named in full7:42

0:09“Yeah it's a first floor bedroom, sash opens about 200 wide —”7:43

Under 125 mm of opening or a compliant restrictor and you're inside the requirement — 200 mm is not. Restrictors need to resist a set force, so a friction stay on its own won't do it.NCC 2022 · Vol 2 · clause named in full…always confirm with your certifier for your specific project.More detail👍 Helpful👎 Not right7:43

Photowhat about this one?7:44

That's an awning sash — the restrictor sits on the arm, so measure the opening at full travel rather than at the frame.7:44

Free answers come from the Code — useful, but the Code doesn't know your window schedule. Upload a project and the same WhatsApp number starts answering from your drawings instead, and sends the page back with the answer.

Upload your plans

Before you ask.

Is it actually free?: Five questions a day, no account, no card, no trial that quietly ends. Link a free account and it goes to fifty.
Do I have to install something?: No. It's a WhatsApp conversation with a business number. If you've got WhatsApp, you've got everything you need.
How do I know it's right?: Every answer names the Code clause it came from, so you can check it. And it tells you to confirm with your certifier — it's a fast second opinion, not a sign-off.
What happens to my plans?: Nothing until you upload them, and you don't have to. Ask Code questions for as long as you like without an account existing.

One question costs you nothing.

Ask the thing you were about to guess at.
