First, put a knowledge base on your web address
Nothing appears publicly until you choose what the address serves. On Brand → Knowledge, open the knowledge base's three-dot menu and choose Show at your-address.yaplet.help. That one choice fills both the public page and the widget's Help tab. The reverse action is Take down from the public site; taking one down leaves the address showing nothing, but the articles are untouched and your AI keeps answering from them. (New to that menu? See what a brand is in Yaplet.)
The logo comes from your brand
You set it once and it is used on your public knowledge base, your public documentation and your public roadmap — one company, one logo.
- Go to Brand → Brand settings → General and scroll to the Brand images section. (It is a section on that tab, not a tab of its own.)
- Under Brand logo, choose the wide version of your mark. Images are picked from your organisation's shared image library — a grid of everything already uploaded, plus an upload tile — so the same file does not have to be uploaded once per place it appears.
- Save.
It is one image, not a light-and-dark pair. That single file is used in both colour modes. If your logo genuinely disappears on one background — an all-white or all-black mark — switch on Add a second version for light or dark and say which mode the second one belongs to. The screen puts it plainly: "Only needed if your image disappears on one of the two backgrounds — an all-black or all-white one, for example. Most images work in both." A live preview shows both modes, and switching the option off deletes the second version rather than hiding it.
Colours and the rest of the look come from your chat widget
The public page is not styled on its own screen. It borrows the appearance of the brand's chat widget, so the colours you pick at Brand → Chat widget → Appearance are what visitors see on the public page too. Change them once and both follow.
A brand with no chat widget still serves its public knowledge base perfectly well — it simply uses the default look. Deleting the chat widget does not take the public page down.
What appears in the header
The top-left of the public page shows your brand logo, and it links back to the knowledge base home. If the brand has no logo, the header falls back to the words "Knowledge Base" instead. A language selector appears on the right as soon as the knowledge base has more than one language configured.
Custom domains are not supported
Public pages are only served on yaplet.help. There is no way to point help.yourcompany.com at your knowledge base — no DNS record to create and no field to fill in. What you can change is the part in front of it, at Brand → Brand settings → Public address. Do that sparingly: every link anyone has already saved stops working the moment you do.
