Rezi for the resume. CoBlack for the search

Rezi was built to solve one problem, and it solves it well. An estimated three in four resumes are filtered out by applicant tracking software before a human reads them, and Rezi exists to get yours through. Jacob Jacquet started it in 2015 after a plain, keyword-clean resume he posted on Reddit went viral, and when Rezi added GPT-3 in 2020 it became the first AI resume builder on the market (Rezi, 2026). Forbes later named it a top pick, and more than four million job seekers have used it since.

Rezi and CoBlack agree on the diagnosis. The machine reads first. Where they differ is how far each one walks with you after the resume is ready.

What Rezi does

Rezi is a resume builder, not an application service. You write your resume inside it, and its AI does three things well. It scans a job description for the keywords that opening rewards and works them in, a feature it calls AI Keyword Targeting. It grades the draft against a 100-point Rezi Score that updates as you type. And it lays everything into one of more than thirty conservative templates built to survive ATS parsing (Rezi, 2026). The Pro plan adds one human resume review a month.

Pricing is clear. The free plan gives you one resume and three downloads. Pro is $29 a month with unlimited resumes, full AI, and the monthly review. A lifetime license is $149 once, and every paid plan carries a 30-day money-back guarantee (Rezi, 2026).

What the reviews say

The public record is strong. Rezi holds a 4.5 out of 5 on Trustpilot across more than 120 reviews, roughly three-quarters of them five stars (Trustpilot, 2026). Reviewers single out the keyword targeting, the live score, and how fast a clean draft comes together. The recurring complaint is service, not software: several customers describe slow or missing support replies, and some who paid for the live resume review say they struggled to hear back (Trustpilot, 2026). The tool is well liked. The help behind it is where the friction sits.

Where CoBlack stands

Here is the ceiling of any resume builder, Rezi included. It perfects one document and hands it back. You still have to find the openings, judge which keywords each one wants, rebuild the resume for that job, fill the form, and submit. Rezi makes the first step excellent. The rest of the search stays on your desk.

CoBlack treats the resume as an output, not the product. It sources roles directly from verified employer ATS feeds and career pages, the same systems Rezi is coaching you to satisfy from the outside. It builds a Career Capability Map from your real experience, and for every opening that matches it writes a fresh resume tailored to that specific job, then applies server-side with no form to fill and no review step to clear. A custom resume per application is the default here, not a task you repeat by hand.

The result is what we count. CoBlack users convert to interviews at 12 times the rate of a standard search (CoBlack internal data, 2026). Not because the resume looks better, but because the right resume reaches the right opening every time, without you assembling it.

Who each tool is for

Rezi is a fair buy for a clear case: someone applying to a handful of roles who wants one strong, ATS-clean resume and is content to carry it through each application themselves. If you are early in a focused search and want a document you trust, $149 once is honest value, and the Rezi Score genuinely teaches you what good looks like.

CoBlack is for that same person once the search stops being a handful of roles. When you are tailoring the tenth resume by hand and filling the fortieth form, the work a resume builder leaves on your desk becomes the work that wears you down. CoBlack does that part, on real fit, while you spend your hours on interviews and the rest of your life.

Rezi makes your resume ready. CoBlack makes it ready for every opening, and sends it.
