ATS Resume Checker — Beat the Resume Filter
Check your resume against ATS filters: parse-safe formatting, missing keywords, and section structure. AI rewrites bullets with impact verbs. Free, in-browser.
Applicant Tracking Systems reject resumes before a human reads them — usually for formatting (tables, columns, fancy headers the parser mangles) or missing keywords from the job description. This checker evaluates your resume the way an ATS parses it and flags what will break.
Paste your resume bullets and the job posting: the AI rewrites weak, duty-style bullets into accomplishment statements with the role's actual keywords woven in — compact, impact-focused, and technical variants. Runs entirely in your browser.

AI rewrites are generated by SmolLM2 (an open-source language model by HuggingFace) running entirely in your browser via Transformers.js and ONNX Runtime Web. Your resume and job description never leave your device. Always proofread AI output against your real experience. The rule-based engine is provided as a deterministic fallback.
How AI resume rewriting really works — illustrated
An Applicant Tracking System (ATS) does the first pass on your resume before a human ever sees it: it parses the file, normalizes sections, and scores how well your text covers the job description's keywords. This tool mirrors that pipeline in your browser — it extracts the top terms from a pasted JD, rewrites each bullet with strong action verbs and quantified outcomes, then re-scans the result to report an ATS keyword coverage percentage. Because the rewrite model (SmolLM2) runs locally via Transformers.js and ONNX Runtime Web, your resume and JD never leave your device.
The same bullet passes through three stages: raw text, a JD keyword scan, and an action-verb rewrite, ending with a coverage score you can act on before applying.
Maya applies for a Senior Backend Engineer role. Her original bullet reads 'Managed a team and built APIs.' After pasting the JD, the tool extracts React, SQL, CI/CD and leadership as keywords, rewrites the bullet, and re-measures coverage.
- Original bullet:"Managed a team of 6 and built REST APIs." — only 4 of 12 JD keywords present (33%)
- Keyword scan:JD extraction returns 12 terms: React, SQL, CI/CD, Kubernetes, leadership, and 7 more
- AI rewrite:"Spearheaded a 6-engineer platform team; designed 12 REST APIs." — action verb + scope + number
- Re-check:Coverage climbs to 10/12 (83%), with the 2 remaining gaps surfaced as actionable suggestions

Frequently asked questions
What makes a resume ATS-friendly?
Single-column layout, standard section headings (Experience, Education, Skills), no text in images or tables, standard fonts, and a .docx or text-based PDF. Beyond format, the parser ranks keyword matches against the job description — which is why tailoring beats spraying the same resume everywhere.
Should I copy the job description keywords exactly?
Use the same vocabulary where it is genuinely true — if the posting says "CI/CD pipelines" and your experience matches, use that exact phrase rather than a synonym the parser won't score. Never stuff keywords for tools you have not used: interviews verify, and the AI rewriter is built to phrase real experience in the posting's language.
