To comply with Linkedin Terms of Service, ProspectSafari does not automatically scrape Linkedin profiles.
However the ProspectSafari Extension lets you add people and companies one at a time from LinkedIn, with its right-click menu. Right-click a person's name or picture in LinkedIn search results, or anywhere on a person's profile, and pick "Add contact".
Chrome then asks whether to add the contact to a prospect you already have with that company's LinkedIn page, otherwise to the last prospect you edited. If you click Cancel, the contact can be added as a new prospect in your "Default list" (click the ProspectSafari icon in the browser toolbar to pick it).
Similarly, right-click a company in a person's "Experience" section and pick "Add company with contact" to add both the company and the contact (their LinkedIn profile, name, job title and so on). On a company page, right-click anywhere and pick "Add company".
Adding the same profile again later updates that contact with what LinkedIn shows you then. The extension reads only what LinkedIn shows you, one person or company per right-click.
Listing Websites
Linkedin is an example of a Listing Website: a directory, review or social site with a page for each company, such as Facebook, Instagram, Trustpilot or Tripadvisor. Admins can add any others the team uses.
Right-click a link to a person or company page on one of these sites and pick "Add URL" to save it on the prospect. The site's logo then appears in the Prospect View: click it to open the saved page.
You can add any specialist listing website that you like. See the tutorial.
Search Tools
In Settings, on the "Link manager" card, an admin can add a search tool related to any Listing Website.

In Settings / Link Manager you can add search tools.
The search tools you pick in the "Search tools" popup are shown on every prospect in the Prospect View, with a light circle around them. Clicking a search tool opens the side window and searches that site for the prospect's company.

Showing the Linkedin and Google Maps search tools.
Right-clicking one of the search results and picking "Add URL" saves that page on the prospect. Now the search tool will be replaced with the listing website logo, allowing the profile page to be opened with a click. For more information, see the Search Tools tutorial.
