CareerBoom meters the applications. CoBlack applies all month

CareerBoom AI spent most of its life as a resume builder, cover letter generator, and job tracker. On July 17, 2026 the San Francisco company shipped the piece that moves it into this category: an Auto Apply Agent that finds openings, tailors the application, and submits it for you. Within a week it reported more than 50,000 applications processed. That is a real launch, and the product around it is more considered than most.

What CareerBoom does

You import a LinkedIn profile or upload a resume, set your target roles and locations, and the agent takes over. Auto Discover scans more than five million newly added listings a month across what the site calls 50 plus sources, ranks them against your profile, then writes a role specific resume and cover letter for each match. You can run it fully automated, or review the matches and apply to each one yourself.

Two things beat the category norm. Recruiter replies land in a dedicated mailbox CareerBoom creates for you, so the responses to a few hundred applications never bury your personal inbox. Few tools in this space offer it. And it says plainly that it targets relevance rather than volume, the opposite of how most of its competitors sell themselves.

What it costs

These numbers come from both companies' own pricing pages.

CareerBoom's free plan does not apply to anything. It gives you three resumes, one job tailoring a month, and three browser autofills. Auto Apply starts at 59.99 dollars a month for 100 applications, with tiers at 250 and 600.

CoBlack's free plan applies to 8 openings a month, at no cost, permanently. Two hundred applications a month is 19.99 dollars. Four hundred is 39.99 dollars.

At its entry tier CareerBoom is about 60 cents an application. CoBlack's 200 for 19.99 dollars is about ten cents. The CareerBoom price carries its full resume and cover letter suite, so you are not paying for submissions alone. But the applications are the metered part, but the applications are the metered part.

What the reviews say

There is little to read yet. CareerBoom has two Trustpilot reviews, both five stars, both written before the agent launched. The 50,000 applications figure is the company's own count, and nobody has published callback or interview conversion data for it. Treat the launch numbers as claims until a review base forms.

Where CoBlack stands

Autonomy is not the difference. On its own pages, CareerBoom's agent applies once you switch it on, and so does CoBlack. The honest contrast sits in where openings come from and how far the application goes.

CoBlack's Auto Search reads validated employer career pages and ATS feeds rather than aggregated boards, so ghost listings never enter the pipeline. CareerBoom names no ATS platform in its launch release, product pages, or pricing.

Then the application itself. Auto Resume writes a fresh resume per opening from your Career Capability Map, and Auto Apply answers the screening and knockout questions that decide most applications before a person reads the resume. Honeit traced a funnel of 300 applicants down to about 50 at pre qualification in June 2026. CareerBoom publishes resume and cover letter tailoring. It says it adjusts answers to each position, without describing screening questions.

Who each is for

If you want one place to write your resume, hold your versions, track your search, and add an agent that handles a controlled number of applications on top, CareerBoom is a tidy suite and the mailbox is a good piece of thinking. A hundred tailored applications a month is a reasonable pace for someone applying selectively.

If you are searching against 250 applicants an opening, SHRM's 2025 figure, a hundred goes quickly. CoBlack gives you 200 applications for 19.99 dollars, sourced from real postings, tailored per opening, screening questions answered, submitted server side. You start free, at eight. A quota tells you when to stop applying. A job search does not work that way.
