Rezi is an AI resume builder. You build your resume inside Rezi, pick a template, and let its tools help you write and format it, with a Rezi Score that rates the resume on 23 key metrics along the way. It is a solid product if what you want is to build a new resume from the ground up.
ATSAlign comes at it from the other direction. You already have a resume, maybe in Word, maybe exported from another builder, and you want to know how well it matches a specific job. You upload it, paste the job description, and get your match score and the first missing keywords. Once it is in, you can edit it in the Studio, tailor a copy to each job, track the application, and download an ATS-safe Word or PDF. No starting over.
As of October 2026, Rezi's free plan lets you build one resume with three PDF downloads, and the full toolset sits on a Pro plan at $29 a month, with a lifetime option for a one time $149. That is fair for a full builder you will use again and again. If you mainly need to pressure test the resume you already wrote, you may not need a full builder plan. ATSAlign keeps the ATS check free, and its AI tools come with ATSAlign Pro, a one-time pass for a fixed number of days that never renews.
These two play well together. Build a clean base resume in Rezi or anywhere else, then run it through ATSAlign against each job you apply to, since the keywords change from posting to posting. A builder gets you a tidy document. A checker shows how well that document matches the role. Doing both covers the format and the keywords.
If you are starting over and want guided help writing every line, a builder like Rezi earns its place. If your resume is basically done and you are applying to real jobs this week, you want the fast, free, job specific check, and the tailoring that follows it, and that is what ATSAlign is for. Pick by where you are in the process.
The entire process takes under 2 minutes and gives you a clear, actionable report.
Upload your DOCX or PDF resume. Text based files work best, because an ATS needs to read the text.
Add the job description you are targeting. We analyze keyword alignment, skills, and structure.
Get your match score and the first missing keywords by name. The full list and AI rewrites come with ATSAlign Pro.
ATSAlign shows you what to fix, not just a pass or a fail.
See the keywords from the job description that your resume is missing, by name. Free checks show the first two; ATSAlign Pro shows the full list.
Understand your ATS score across skills, experience, and formatting, not just one opaque number.
With ATSAlign Pro, AI rewrites your bullet points to include the missing keywords where they fit what you actually did. It does not invent experience.
ATSAlign compares your resume with the job description you paste and shows the keywords, skills and formatting issues that matter when recruiters search an ATS. No outside tool can see how a particular employer has set up its own ATS, so treat the score as a guide.
