Overview

CareerBoom AI automates job hunting. It matches against skills and preferences across a claimed five million new listings a month, applies automatically with a customised application each time, generates ATS-optimised resumes and per-role cover letters, tracks applications, interviews and follow-ups on a dashboard, offers one-click applying from job boards through a browser extension, and routes employer replies to a dedicated mailbox.

The dedicated mailbox is a genuinely thoughtful detail. Anyone applying at volume loses replies in a personal inbox among everything else, and missing the one response that mattered is the actual cost of a scattergun search. Separating the channel is the difference between automation that helps and automation that generates noise you then fail to read.

It is made by Castel, starts free with pricing on a separate page, and reports more than 50,000 auto-applied jobs. The objection has to be stated plainly: this is one half of an arms race. Employers already screen with AI because applications arrive in volumes no human can read, and tools like this increase that volume, which hardens the screening, which increases the incentive to automate. A customised application generated without you reading the posting is also a claim about your interest that you have not actually made, and auto-applying at scale can reach employers you would not want to work for.
