Overview

Save pages, people and companies from any site to Signal, and run the LinkedIn enrichment and messages you approve.

Signal is a sales and content workspace. This extension connects your browser to your own Signal account. Save what you're looking at, from any website: - Save this page: right-click any article, report or post and choose Save this page to Signal. It goes into your Signal knowledge bank as you see it, cleaned, titled, summarised and filed. Already saved? Signal tells you and never makes a second copy. - Add a person: highlight someone's name, role and email on any page (a team page, a speaker list, an email signature) and right-click Add to Signal contacts. Signal keeps only what you highlighted and checks your contacts first so nobody is added twice. - Add a company: on a company's own website, right-click Add this company to Signal to add its name, website, description and location. Signal side panel: - Talk to James, your Signal assistant, beside any page, by typing or by voice note. Tick Use this page to let James read the page you are on. - Add the people or companies on a page, or the rows you choose from a spreadsheet. LinkedIn work you set up in Signal: - Right-click a LinkedIn post to draft a comment in your own voice, or to save the people engaging with it or talking on it. - Shows who viewed your profile and who engaged with your own recent posts, read in the hourly LinkedIn sync, so you can add them to a list and message them. - Add a person to Signal straight from their LinkedIn profile. - Reads the LinkedIn profiles you ask Signal to enrich, through your own LinkedIn login, one at a time and paced like a person, with random gaps and regular breaks. - Sends the LinkedIn messages and invitations you have approved in Signal. - Syncs your LinkedIn inbox so replies show in Signal. - Stops all LinkedIn work the moment LinkedIn shows a security check, until you restart it. Nothing runs on other websites unless you click. You pair the extension with a token from Signal Settings; everything it captures goes to your own account only.
