Surfacing contacts by topic

The Grenier browser extension surfaces the contacts most relevant to the page or profile you're currently viewing, drawing on your shared history.

You can also narrow that list yourself: type one or more topics in the extension and it ranks your contacts by how many of them match the interests Grenier has already worked out for each person.

That box is a filter, not an edit. Choosing a topic never changes a contact, and the selection clears when you close the popup.
