Free ATS Resume Checker — find the keywords you're missing before the robot rejects you

How ResumeRadar scores your resume

Applicant Tracking Systems (ATS) like Workday, Greenhouse, Lever, iCIMS, and Taleo parse your resume into structured fields, then recruiters search and filter candidates by keyword. Roughly estimated 97% of Fortune 500 companies and around 70% of large employers overall used some form of ATS in 2026, so the practical question isn't "will a robot read my resume?" — it's "will a recruiter's keyword search find me?"

ResumeRadar mirrors that workflow. The keyword score (50%) extracts skills, tools, and certifications from the job description using a 240+ entry taxonomy plus frequency analysis of the posting itself, then checks each one against your resume — weighted by how often the employer repeats it. The section score (20%) verifies parsers can find your contact info, summary, experience, education, and a dedicated skills block. The formatting score (15%) hunts for parser-breakers: table layouts, decorative bullets, header/footer artifacts, and inconsistent date formats. The impact score (15%) measures how many bullets start with a strong action verb and contain a number — the two strongest predictors that a human reader keeps reading.

All scores are estimates produced by transparent rules — no two ATS platforms behave identically, and a great score doesn't guarantee an interview. Use the missing-keyword list to tailor honestly: only add skills you genuinely have, phrased the way the posting phrases them (e.g. write both "Kubernetes" and "K8s" if you use it, because exact-match search is still common).

5 ATS myths that waste job seekers' time

How to tailor your resume in five steps

Tailoring isn't rewriting from scratch — it's a tight loop you can run in about ten minutes per posting. First, import or paste both documents: your resume and the exact job ad you're targeting (generic scans give generic results). Second, scan and read the gap table — focus on the high-priority missing keywords, because the posting repeats those most and recruiters search on them first. Third, add only what's true: for each missing term you genuinely have, find the bullet where you already did it and rephrase it in the posting's exact words (write both "Kubernetes" and "K8s" if you use it, since exact-match search is still common). Fourth, fix the Bullet Doctor flags — open every bullet with a strong verb and land a number in at least half of them. Fifth, re-scan and watch the gauge climb, then save the scan so you can compare versions across applications. Honest tailoring beats volume: a handful of closely-matched applications converts better than a hundred identical ones.

ResumeRadar pairs well with other free AppVitamins tools for the rest of the hunt: use Paste & Ask to interrogate a long job description, Summarizer to boil a wordy posting down to its real requirements, and PocketLLM as a private in-browser AI assistant for interview prep. When you're ready to keep the upgrades, the AppVitamins store has ResumeRadar Pro and the full tool bundle.
