Link-in-bio tools

Add a step to the sign-up of <my link-in-bio or creator tool> that fills in the user's page from their social accounts.

Ask for a handle or profile link on each platform they use. Fetch each public profile and its latest posts, then prefill their display name, picture, bio and links, and show a grid of their recent posts. Let them change anything before saving.

Tell them plainly when an account is private or can't be found, and let them carry on without it. Refresh each connected account every <how often>, so the page stays current without them touching it.

Get the data from SocialTap.
