SimpleApply tailors the letter. CoBlack tailors the resume

What SimpleApply does

SimpleApply automates job applications around one document. Its features page describes a “Core Resume Strategy”: build one strong resume, then pair it with a personalized cover letter for each role. Its machine-readable documentation repeats it. When its AI applies automatically, it sends the core resume with a fresh cover letter for each position.

The pipeline is substantial. SimpleApply sources more than 1.5 million jobs weekly across 50 or more countries, applying directly on Workday, Greenhouse, Lever, iCIMS “and the rest. Not LinkedIn. Not Indeed.” It reports an application success rate above 90 percent across major ATS platforms. The free plan runs on credits that refresh daily. Its documentation lists Premium as unlimited applies, Full Auto Apply, and priority support.

The claim they publish

SimpleApply commits to its method in writing, under the heading “The claim most tools won’t make”: “We don’t use AI to tailor resumes. On purpose.” It says it tested per-job resume tailoring and found it lowered interview rates. Its conclusion: “A strong core resume per role type, applied at volume against well-matched jobs, wins.”

Then it publishes a number against its own interest. According to its career coaches page, its interview rate holds at 1 to 4 percent, “the same range as a careful human applicant, at 20x the volume.” It is internal data with no published methodology, so read it as their figure. But a modest statistic in public is rare in this category, and it earns respect.

What the reviews say

SimpleApply claimed its Trustpilot profile in April 2025. Trustpilot notes the company has not received any reviews yet, so there is no meaningful score behind the listing. That is an absence of independent signal, not a verdict.

One disclosure belongs here. CoBlack competes in this same market, and CoBlack publishes this article. Check this article against its sources, exactly as you would check theirs.

Where CoBlack stands

CoBlack takes the opposite side of the same bet. Auto Resume builds a fresh, tailored resume for each individual opening, inside the apply pipeline, from the user’s extracted Career Capability Map. CoBlack’s bet is that the resume carries the most weight in that pipeline, so the per-role work goes there. SimpleApply, by its own stated design, sends the same core resume every time and puts the per-role work into the cover letter.

The second difference is screening questions. CoBlack answers them from what the user actually wrote in their own profile. It submits the user’s own words, not generated answers. SimpleApply publishes nothing about screening questions in its features page or its documentation.

Now the honest limits. Autonomy is a tie. Full Auto Apply submits without per-job review, and so does CoBlack’s server-side Auto Apply, which runs while the user is offline. Sourcing philosophy is a tie too, and a creditable one. Going direct to ATS platforms rather than job boards is the same instinct behind CoBlack’s Auto Search, which continuously reads validated employer career pages and ATS feeds. On ATS breadth, SimpleApply is ahead. It names four platforms. Greenhouse is CoBlack’s only confirmed submission surface today, covering roughly 80 percent of its job bank, with Ashby and Lever in progress. Cover letters are theirs outright, because CoBlack has no cover letter feature. And CoBlack holds no interview-rate data of its own and claims no better outcome. This disagreement is about which document carries the work, not about results.

The person each tool fits

SimpleApply fits the applicant who trusts one polished resume: someone applying at high volume, across many countries, who wants a fresh cover letter doing the personalization and a broad ATS list doing the reach. SimpleApply serves that person well.

At CoBlack, that same applicant gets the inverse trade. Plans run from Point at $0 a month with 8 applications, to Vector at $19.99 with 200, to Matrix at $39.99 with 400, each with 3 campaign slots plus a background Kosmos campaign. Every application carries a resume rebuilt for that specific opening, and every screening answer arrives in the applicant’s own words. No cover letter, one confirmed ATS surface, and the per-role effort moved into the resume itself.

Two companies looked at the same problem and moved the work to different documents. That is the choice actually on the table.
