The best ATS resume checker in 2026 is the one that tells you exactly which keywords are missing from your resume before you submit, not after you get rejected. We tested Resume Optimizer Pro, Jobscan, ResumeWorded, Enhancv, and Zety against the same set of job descriptions using identical base resumes. The differences in score accuracy, keyword detection, and actionable feedback were significant. Here is the full breakdown.
Quick Comparison: ATS Resume Checker Tools at a Glance
This table covers the five most widely used ATS resume checkers. All free tier details were verified in April 2026. Pricing reflects individual monthly plans without annual discounts.
| Tool | Key Feature | Free Tier | Best For | ATS Score? |
|---|---|---|---|---|
| Resume Optimizer Pro | Real ATS scoring logic + full resume rewrite in seconds | Unlimited ATS checks, score + keyword gap shown | Job seekers who want optimization, not just diagnosis | Yes, with keyword breakdown |
| Jobscan | Deep ATS simulation across 100+ platforms | 5 scans/month | Power users scanning many roles simultaneously | Yes, match % score |
| ResumeWorded | Line-by-line feedback with score per section | 1 score check | Candidates who want granular section-level critique | Yes, section scores |
| Enhancv | Visual resume builder with built-in ATS check | Basic check only, export paywalled | Candidates rebuilding from scratch inside a builder | Partial (no breakdown) |
| Zety | Template builder with ATS tips during editing | No score check without subscription | Beginners building a first resume | No (guidance only) |
How We Tested These ATS Resume Checkers
We used three test resumes (entry-level marketing coordinator, mid-level software engineer, senior project manager) and ran each through all five tools against five real job descriptions sourced from LinkedIn and Indeed in March 2026. We measured four dimensions for each tool:
Keyword detection accuracy
How many of the keywords flagged as missing were genuinely present in the job description versus false positives or irrelevant suggestions. We manually validated every flagged keyword against the posting.
Score calibration
Whether the tool's score reflected actual qualification alignment. We compared scores before and after adding 10 targeted keywords to the resume, measuring how much each addition moved the score.
Actionability of feedback
Whether the tool told you specifically what to change and where to put it, versus generic advice like "add more keywords." Specific is useful. Generic is noise.
Free tier value
Whether you could get meaningful diagnostic information without a credit card. Several tools surface a score but hide the detail behind a paywall, which makes the free tier close to useless for actual improvement.

Optimize My Resume FreeResume Optimizer Pro: ATS Checker + Full Optimization
Resume Optimizer Pro is the only tool in this comparison that combines ATS scoring with full resume rewriting in one step. Every other tool tells you what is wrong. Resume Optimizer Pro tells you and then fixes it.
What it does
Upload your resume (PDF or DOCX) and paste a job description. The tool parses both, calculates a keyword match score, identifies required and preferred skills missing from your resume, and produces an optimized version with the correct keywords integrated naturally into your experience bullets and skills section. The entire process takes under 60 seconds.
The free ATS checker shows your score and the full keyword gap list without requiring an account. Full optimization, cover letter generation, and unlimited tailored downloads require a paid plan.
What it does well
- Free score and keyword gap with no sign-up
- Distinguishes required vs. preferred keywords
- Produces optimized resume text, not just a list of gaps
- Covers cover letters and job matching in the same tool
- API available for staffing agencies and developers
Where it falls short
- No per-platform ATS simulation (it scores against the job description, not a specific ATS platform like Workday or Taleo)
- No LinkedIn profile review
- Newer tool, smaller brand recognition than Jobscan
Best for: Job seekers who want to fix their resume, not just diagnose it. If you are submitting to multiple roles per week, the time savings on tailoring alone justify the cost. The free tier is genuinely useful for initial scoring before committing to any changes.
Jobscan: The Market Leader in ATS Simulation
Jobscan has been around since 2014 and is the most established name in ATS resume checking. With over 1 million users and partnerships with major ATS vendors, its platform simulates specific ATS parsing behavior more comprehensively than any competitor.
What it does
Jobscan scans your resume against a job description and simulates how specific ATS platforms (Workday, Taleo, Greenhouse, Lever, iCIMS, and dozens more) will parse it. It identifies hard skills, soft skills, job title alignment, and education requirements as separate scoring categories. The LinkedIn profile optimization tool is a meaningful differentiator: most job seekers neglect their LinkedIn profile even while optimizing their resume, and recruiters use both.
According to Jobscan's own published data, users who score 80% or above on the match scan are 50% more likely to get an interview callback. Independent testing by TopResume in 2023 found that tailored resumes scored 40% higher on ATS platforms than generic versions from the same candidate.
What it does well
- Per-platform ATS simulation (100+ platforms)
- LinkedIn profile optimization included
- Detailed skill categorization (hard/soft/job title)
- Longest track record in the space (founded 2014)
- Cover letter scanner alongside resume scanner
Where it falls short
- Only 5 scans/month on the free tier
- Does not rewrite your resume, only tells you what to change
- Interface feels dated compared to newer tools
- Paid plans start at $29.95/month, which is expensive for casual job seekers
Best for: Active job seekers applying to 10 or more roles per month who want platform-specific ATS simulation and LinkedIn optimization in one subscription. Less suitable for candidates who want the resume actually rewritten, not just diagnosed.
ResumeWorded: Granular Section-by-Section Scoring
ResumeWorded takes a different approach: rather than a single match score, it evaluates each section of your resume independently and provides line-by-line feedback on what is weak and why. It also includes a LinkedIn profile grader and an industry-specific scoring mode.
What it does
Upload your resume and ResumeWorded assigns scores to each section (summary, experience, skills, education) and flags individual bullets that are too vague, missing quantification, or using weak action verbs. The "Targeted Resume" mode accepts a specific job description and adjusts scoring based on keyword alignment. In our testing, the section-level scoring was genuinely useful for identifying which part of the resume was dragging down the overall match score.
What it does well
- Section-level scores identify exactly where to focus
- Line-by-line bullet quality feedback
- Strong LinkedIn profile grader
- Industry-specific score benchmarking
Where it falls short
- Free tier allows only 1 scan (very limited)
- Does not simulate specific ATS platforms
- No automated resume rewriting
- Keyword suggestions sometimes miss context (flags synonyms as missing when the concept is present)
Best for: Candidates who want to understand the quality of their writing at the bullet level, not just keyword coverage. Strong choice for a one-time resume audit before a significant job search push.
Enhancv: Builder-First with a Built-In ATS Check
Enhancv is primarily a resume builder with visual, two-column templates. The ATS check is a secondary feature integrated into the builder, not a standalone tool. In 2025, Enhancv added an AI-powered resume writer and a content analyzer that flags vague bullets and generic language.
What it does
Within the builder, Enhancv shows a content analyzer panel with suggestions for improving bullet quality, adding missing sections, and strengthening language. The ATS check assigns a compatibility percentage but does not break down which specific keywords are missing or which section is underperforming. Exporting the finished resume requires a paid subscription.
One important caveat: Enhancv's default templates use two-column layouts, which score poorly on actual ATS systems despite the tool's built-in ATS check showing favorable numbers. Our test resumes built in Enhancv and exported scored 12 to 18 percentage points lower on third-party ATS scanners than the tool's own score suggested. This gap matters in practice.
What it does well
- Polished visual templates good for industries where design matters
- Bullet quality analysis flags weak language
- All-in-one builder and checker in one interface
Where it falls short
- Two-column default templates hurt real ATS parsing (12 to 18% score gap in our tests)
- ATS check does not show keyword gap details
- No export without subscription
- Optimistic internal scores that do not reflect real-world ATS results
Best for: Creative and design fields where visual presentation matters alongside ATS compatibility, or candidates who prefer working within a builder interface. Not recommended if ATS pass rate is your primary concern.
Zety: Template Builder with Guided ATS Tips
Zety is one of the most recognized resume builder brands, with high search visibility and a large template library. However, its ATS checking capability is the weakest in this comparison. The tool provides general ATS guidance during the building process but does not produce a scored ATS analysis against a specific job description.
What it does
Zety guides users through resume creation with section-by-section prompts, content suggestions, and formatting choices. ATS-related advice appears as contextual tips ("Use standard headings," "Avoid tables") rather than a scored analysis. There is no upload-and-check workflow for existing resumes. The platform is built for creating resumes from scratch, not auditing ones you already have.
Subscription costs are relatively high ($23.70 to $35.70/month depending on billing cycle), and the charging model has generated consistent complaints from users (Zety surfaces a partial resume before requiring payment, which many users find misleading). The quality of the templates is high, and the content suggestions during building are genuinely useful for first-time resume writers.
What it does well
- Large high-quality template library
- Strong guided writing prompts for first-time resume builders
- Clean, professional output
Where it falls short
- No scored ATS analysis against a job description
- Cannot upload and audit an existing resume
- Subscription model is among the most expensive in this group
- Charging UX has generated negative user feedback on Reddit and Trustpilot
Best for: First-time resume writers who need guided help building a professional document and do not yet need deep ATS scoring. Not suitable as a primary ATS optimization tool.
Head-to-Head Test Results
We ran the same mid-level software engineer resume against a real software engineer job posting (100+ requirements listed) through all five tools and recorded the results. Where tools did not produce a numeric score, we noted the type of output provided.
| Tool | Initial Score | Score After Adding 10 Keywords | Score Sensitivity | Free Tier Showed Score? |
|---|---|---|---|---|
| Resume Optimizer Pro | 61% | 79% | +18 points (high) | Yes, full gap list |
| Jobscan | 58% | 76% | +18 points (high) | Yes, with skill categories |
| ResumeWorded | 64/100 (section avg) | 78/100 | +14 points (medium) | Score shown, detail locked |
| Enhancv | 72% (internal) | 81% (internal) | Optimistic vs third-party tests | Score only, no breakdown |
| Zety | No score | No score | Not applicable | No score at all |
Internal scores from builder-integrated tools (Enhancv) may differ significantly from scores produced by real ATS platforms or third-party checkers. Score ranges differ across tools and are not directly comparable as absolute numbers.
Pricing Comparison (April 2026)

Frequently Asked Questions
Bottom Line
The ATS resume checker market is genuinely useful, but not all tools serve the same need. Jobscan leads on depth of ATS simulation. ResumeWorded leads on writing quality feedback. Resume Optimizer Pro is the only tool that combines free diagnostic scoring with automated resume rewriting, which is the gap that most job seekers actually need closed.
Whichever tool you use, the principle is the same: score your resume against the specific job description before submitting, not after. The resume that passes ATS screening is almost always a tailored one. Our complete ATS score guide covers how scoring works and the exact steps to improve your number before each application.
