There are a lot of tools available that promise to improve your resume. But when you’re applying for jobs, time is at a premium. You can’t spend time wading through every resume tool under the sun. Here, we’ll talk about the major differences between resume tools so you can choose the one that works for you–simplify your resume writing once and for all.

Resume Builder

Resume builders help you compile your work history and experience into a resume. The best resume builders help you encapsulate and pitch your most persuasive self, and work with you to create the initial draft.

A couple of our favorite resume builders are Rezi, an easy-to-use resume tool that helps you generate PDF-enabled resumes and CV Maker, which we like for its clean resume templates and capability to export resumes in PDF, HTML, and TXT file formats.

Resume Grader or Reviewer

A resume grader reviews your resume, and then, like the name implies, gives you a letter grade (A-F, just like in school) based on a number of factors that make resumes appealing to hiring managers.

RezScore, a resume builder, grades your resume based on its brevity, impact, and depth. While RezScore offers some advice, it doesn’t offer any specific method for improving your resume, likely leaving you without a way to actually correct issues.

As an alternative, a resume reviewer lets you know how effective your resume is in a number of categories, including content, style, and length. The reviewer then offers advice about how to make your resume better.

One example is Ladders’ Resume Reviewer. While this resume tool lets you know if you’re using proper grammar and spelling, it offers only limited suggestions about how to make improvements. You might know what’s wrong with your resume, but there is limited guidance as to how you should change it.

Resume Scanner

A resume scanner combines the best aspects of a resume grader and resume reviewer into a single tool. Additionally, a scanner checks to see that the skills and keywords used in both the job description and your resume are the same. Many companies are using Applicant Tracking Systems (ATS), or automated systems that scan resumes for a good match using the job’s desired keywords. A scanner ensures that your resume makes it through the ATS.

Using an advanced algorithm, Jobscan checks to see that your resume keywords and the keywords on the job description match. Jobscan then provides more feedback than other, similar tools by suggesting keywords you should include in your resume to increase your match rate. Additionally, Jobscan’s free resume templates provide you with the best format for making your resume ATS-readable and attractive to hiring managers. Remember, the improvements recommended by resume tools, though beneficial, are not enough. Since recruiters conduct different keyword searches using words most relevant to each job, the best guarantee you’ll get noticed is by taking the time to tailor each resume with the most pertinent keywords.
