What is an internal page?
An internal page is a real page in your site that only exists for you and Ullbek inside the builder. It lives in a special folder called _internal. You can open it, click around, and iterate on it in the preview — just like any public page.
The difference is simple: visitors never see it. When you publish (or re-publish), everything under _internal is left out. It is not on your free subdomain, not on a custom domain, not in the sitemap, and not crawlable by search engines.
A builder-only workspace — not part of the public website.
That private space is where the agent keeps the site brief, tries design options, and stores notes that should never become public content by accident.
The rule that matters: never published
Publishing your site only ships the public pages. The internal area is excluded every time — free subdomain or custom domain, first publish or tenth update. You do not need a setting to keep it private. That is how the product works by design.
Internal means unpublished — not a vault. Don't store passwords, API keys, or secrets in any site file, internal or public. Keep those out of the project entirely.
How to open them
Internal pages are fully visible to you in the builder. The privacy is about publishing, not about hiding them from you.
-
The Site Brief — info icon
The most important internal page is the Site Brief. Open it anytime with the info icon in the preview toolbar. That's the living description of your site — brand, structure, decisions.
-
Ask in chat
Tell Ullbek what you want to see: “open the site brief,” “show me the internal demos,” or “list everything under internal.” The agent can navigate the preview there for you.
-
Browse and iterate
Once open, internal pages behave like normal pages — scroll, click, refresh after edits. They just never ship when you hit publish.
The Site Brief
Every site has a Site Brief at /_internal/siteinfo.html. It is the authoritative, living description of what this site is — purpose, audience, colors, fonts, page structure, image style, and key decisions.
Ullbek keeps it current as the project evolves. A fresh brief is how continuity works across sessions: the agent remembers brand rules, what not to redo, and where the site is headed.
Changed your mind about colors, tone, or structure? Say so in chat — “update the site brief: warmer and more editorial.” The agent rewrites the brief so future work follows the new direction.
Other useful things to keep internal
The Site Brief is the flagship internal page, but the area is for any durable material that should stay out of the public site.
Design options & comparisons
Nav A vs Nav B, two hero treatments, card styles side by side. Compare freely without polluting the live site. See Demo pages for the full pattern and copy-ready prompts.
Working notes & research
Competitor notes, content drafts, decision logs — durable context for the agent, not public content.
Prototypes & half-finished layouts
Try an interaction or layout safely. Ship only what you approve to a public page.
Brand playgrounds & component boards
A private place to see fonts, buttons, and cards together — reusable by the agent, not a visitor destination.
Pitch or review pages
Material meant for a controlled audience (investors, a client review) rather than SEO and the open web.
Internal pages are saved with your project and still there next session. They are durable working material — they just never publish.
How they work day-to-day
Editable like any page
Ullbek can create, update, and reorganize internal pages the same way it works on public ones.
Uses your real brand
Internal demos can pull the site's real CSS, fonts, and images so options look like the finished product.
Saved with the project
Close the tab, come back tomorrow — internal pages are still there, ready to open or refine.
Excluded on every publish
No checklist item. No toggle. Publish as usual — the public site never includes _internal.
How to ask for one
You don't need special syntax. Describe what you want kept private, and Ullbek will put it under _internal.
What belongs vs. what doesn't
Belongs in internal
- The Site Brief and brand decisions
- Design comparisons and demo pages
- Drafts you want to review before publishing
- Working notes, research, and experiment pages
- Private reference boards for the agent
Doesn't belong in internal
- Anything a visitor or search engine should see — that goes on a real public page
- Secrets (passwords, API keys, private credentials) — keep those out of the site entirely
- Content you intend to share via a public URL — internal pages have no public address after publish
Common questions
Can visitors find my Site Brief?
No. The Site Brief lives under _internal, is never published, and is not on your public URL. Only you (and the agent, in the builder) can open it.
Do internal pages count toward my site?
They are part of the project in the builder and are saved with it. They do not ship when you publish, and they are not part of the public website visitors load.
Can I delete the whole internal area?
You can remove demos and notes anytime. Keep the Site Brief if you can — the agent relies on it for continuity. If you delete it, ask Ullbek to recreate one from the current state of the site.
Can I share an internal page with someone else?
Not via the published site. For reviews, use the builder session together, share screenshots, or promote the finished content to a public page when you're ready.
Is this the same as “unpublishing” the whole site?
No. Taking a site offline is a publishing action that affects the public site. Internal pages are simply never included in any publish. See Publishing & going live for how publish, subdomains, and custom domains work.
