Each tab, collection and article in your docs has Who can read. Use it to keep some docs for signed-in readers or for certain reader groups, while the rest of your portal stays public. To make the whole portal private instead, see Make your portal private.
Where to find it
A tab: open the tab in Docs and pick its Access tab.
A collection: open the collection and choose Settings. Who can read is in the Access card. A new collection's dialog has it too.
An article: in the editor, choose Settings. Who can read is in Article settings.
Then choose Save, or Save changes in Article settings.
Who can read
Inherit (the default): whoever may read what it's in. The option says who that is, like "Anyone can read it". For a tab, that's everyone who may read your portal. For an article in a collection, it's named after the collection, like Inherit from Billing.
Signed-in readers: anyone signed in on your portal, however they signed in.
Specific groups: readers in one of the groups you tick. With none ticked, only your team can read it. If you have no groups yet, Create one opens Settings → Groups.
A page is for whoever every level above lets in: its tab, each collection it's in, then the page itself. So a collection or article can only narrow what's above it. Your team reads everything.
Specific groups is on the Business plan. Signed-in readers works on every plan.
People without access
When some people can't read a page, People without access chooses what they see of it:
Hide: it isn't listed, and its link says the page wasn't found. Nobody learns it's there. This is what happens when no level says otherwise.
Show with a lock: its title is listed with a lock. Opening it asks them to sign in, or says they don't have access, and never shows the content. A locked tab or collection shows nothing inside it.
Inherit: as the level above.
People who can't read a page don't get it in search, AI answers or the widget either. A locked page shows up in search by its title only. Your sitemap and llms.txt list only what's for everyone, and search engines are asked not to index locked pages.
Check what readers see
Preview as a reader, below People without access, opens the page on your portal as people who aren't signed in see it. For an article, it's there once the article is published.
If your plan changes
On a plan without reader groups, pages for Specific groups are your team's only until the plan is back. Your settings are kept.
