JobSignal is a Chrome extension that hunts the job market around the clock, scores every fresh posting against your CV with AI (0 to 100, with the reasons), and emails you the ones worth applying to. Open a posting on any job site and see your score right on the page. Each match comes with a game plan: why it fits, the gaps, a message to the recruiter. Free for 48 hours, no card. Students stay free, others $4.99 or $7.99 a week. Read-only: never auto-applies, never sells your data.
