Skill Gap Analyzer
See What You Prove, List, and Miss
Compare a job description with your resume to see which skills you already demonstrate, which you list without supporting evidence, and which job requirements aren't detected in your resume.
What This Tool Actually Compares
Rezup compares the skills and requirements detected in a job description with the evidence found in your resume. A skill marked Missing means it was not detected in your resume - not necessarily that you don't have the skill.
The goal isn't just a missing-skills list. It's to show whether your resume actually demonstrates what the job expects, so you know what to check before you apply.
What you get from every skill gap check
A precise picture of which required skills you already demonstrate, which you only list, and which you're missing.
Strong Match skills
Skills the job asks for that your resume demonstrates in a bullet, title, or project - your strongest ground.
Partial Match skills
Skills you've listed but never demonstrated in context - easy wins if you actually have hands-on experience.
Missing Skills
Skills the job description asks for that Rezup didn't detect in your resume - a prompt to check, not proof you lack them.
Required vs. preferred priority
When the job description distinguishes must-haves from nice-to-haves, your results are grouped the same way.
What should I fix first?
A prioritized list: required gaps before preferred ones, missing skills before partially-shown ones.
Free core analysis
The buckets, the priority grouping, and the fix-first list are all free, rule-based, and require no signup.
How to Use the Skill Gap Analyzer
- 1
Paste the job description
Rezup identifies the required and preferred skills mentioned in the role.
- 2
Add your resume
Paste your resume text so Rezup can check it against those requirements.
- 3
Review Strong Match, Partial Match, and Missing Skills
See exactly which skills you demonstrate, which you only list, and which aren't detected.
- 4
Check which gaps matter most
Required skills that are missing or only partially shown outrank preferred ones - Rezup orders them for you.
- 5
Strengthen genuine skills with real evidence
Turn a listed skill into a demonstrated one by adding it to a real experience or project bullet - only if it's true.
- 6
Re-check your resume
Run the analysis again after updating your resume to confirm the gap is closed.
See How a Skill Gap Analysis Works
Illustrative example only - not a real job posting, and not a guaranteed result for any resume.
Example job requirements
Required
- Java
- Spring Boot
- AWS
- Kubernetes
Preferred
- Docker
- Terraform
Example resume analysis
- Java (Required) → Strong Match
- Spring Boot (Required) → Strong Match
- AWS (Required) → Partial Match
- Kubernetes (Required) → Missing
- Docker (Preferred) → Strong Match
- Terraform (Preferred) → Missing
Recommended action
- AWS: If you genuinely have AWS experience, strengthen an existing experience bullet with the work you actually performed.
- Kubernetes: Only add Kubernetes if you genuinely have experience with it - it's required for this role, so it's worth prioritizing if true.
- Terraform: Terraform is listed as preferred rather than required, so it's a lower priority to address than Kubernetes.
Listing a Skill Isn't the Same as Demonstrating It
A skill shown in context gives a recruiter clearer evidence of how you have used it than a skill that appears only in a Skills section. Rezup therefore separates contextual evidence from standalone skill-list mentions.
That's the gap this tool surfaces as your Partial Match bucket: skills you already have listed, that the job description also asks for, but that never show up anywhere else on your resume. If you genuinely have hands-on experience with them, moving them into a real bullet point is usually the single highest-leverage fix you can make.
Weak
Skills: “AWS”
No supporting experience.
Stronger
Skills: “AWS”
Experience: “Deployed Spring Boot services on AWS using EC2 and S3...”
Only add or strengthen a skill when it accurately reflects your real experience. Never fabricate experience to close a gap.
Don't Add Skills Just Because They're Missing
A missing skill is a prompt to review your experience, not an instruction to add the keyword.
If you genuinely have it
- Demonstrate it in a relevant experience bullet.
- Add it to a project if applicable.
- Mention a certification when relevant.
If you don't have it
Don't add it simply to improve your match. Make sure any evidence you add is truthful.

Frequently asked questions
What is a skill gap analyzer?
A skill gap analyzer compares the skills a job description asks for against the skills your resume actually shows. Rezup's version splits the result into three buckets: Strong Match (skills you demonstrate), Partial Match (skills you list but never show in context), and Missing Skills (skills the job asks for that Rezup didn't detect in your resume).
How does a skill gap analyzer work?
Rezup extracts the required and preferred skills from a job description you paste in, then scans your resume text for each one - checking not just whether the term appears, but whether it shows up in a job title, experience bullet, or project, versus only in a bare Skills list. The comparison is 100% rule-based; no AI is involved in computing the three buckets.
How do I find missing skills from a job description?
Paste the job description first, then paste your resume. Rezup lists every required and preferred skill it detected in the job description that doesn't appear anywhere in your resume text as your Missing Skills bucket.
Does a missing skill mean I don't have that skill?
No. It means Rezup did not detect that skill in the resume you provided. You may have the skill but simply haven't demonstrated it on your resume - a missing skill is a prompt to review your experience, not proof that you lack it.
What is the difference between a skill I list and a skill I demonstrate?
A listed skill appears only in your Skills section - a bare word in a list. A demonstrated skill shows up in context: a job title, an experience bullet, or a project description that shows the skill in use. Rezup's Partial Match bucket is exactly this gap - skills you've listed that the job also asks for, but that never appear anywhere else on your resume.
How should I use a skill gap report?
Start with required skills that are Missing, then required skills that are Partial Match, then preferred skills - in that order. For any gap, only take action if it's genuinely true of your experience: move a real skill into a bullet point, or leave it out. Don't add a skill to your resume just because the report flagged it as missing.
What do I get for free vs. with a Rezup account?
The three skill buckets, the required-vs-preferred grouping, and the What Should I Fix First prioritization are all free, rule-based, and require no signup. A Rezup account additionally lets you save your resume and build it further with Rezup's free Resume Builder - it does not currently add a different analysis on this page.
