How it works

  1. 1

    Paste your resume and the job description

    Both matter: the optimizer tailors to the specific posting, which is what actually moves an ATS match score. No upload required — or run the free checker first with no account.

  2. 2

    Get your keyword gap report

    See the exact skills and terms the job asks for that your resume is missing — the difference between landing in recruiter search results and being invisible.

  3. 3

    Get a rewritten, scored resume

    A tailored rewrite with the gaps closed inside real bullet points, an ATS score before and after, a cover-letter opening, and your strongest interview talking points.

Resume optimizer vs checker vs scanner

Resume checker

Fast diagnosis: formatting risks, missing keywords, and whether your resume looks ATS-readable.

Resume scanner

Match report: compares your resume to a job description and shows keyword or score gaps.

Resume optimizer

Action step: rewrites your resume for that job, closes gaps naturally, and shows the before/after score.

If you only want a fast diagnosis, start with the free resume checker. If you want a job-specific draft you can submit, use the optimizer on this page.

Why a generic resume gets filtered out

Before a recruiter sees your resume, an applicant tracking system parses it and ranks it against the job's requirements. A resume written for "jobs like this" matches loosely; one tuned to the actual posting matches the terms the recruiter searches for. That gap — not formatting alone — is why strong candidates get auto-filtered. Our study of 503 S&P 500 careers sites found Workday alone screens ~30% of large-company applications, each parser with its own quirks.

The optimizer closes that gap automatically: it surfaces the missing keywords (see what terms your role tends to need in our resume keywords by role data) and rewrites your bullets so they read naturally to humans and parse cleanly for machines.

Frequently asked questions

How much does the resume optimizer cost?
It starts with a 3-day free trial with no card required, including 5 AI generations. Each optimize run (which includes the before/after ATS score) counts as one generation. After the trial it is $17.94 per 6 months — that works out to $2.99/month, billed once — or $4.99/month if you prefer to pay monthly. Both plans include 30 AI generations per month, a 30-day money-back guarantee, and one-click cancellation. If you want something genuinely free with no account at all, run the instant resume checker.
How do I optimize my resume for a specific job?
Paste the resume you already have plus the full job description, then run the optimizer. It reports the keywords the posting expects that your resume never says, rewrites the relevant bullets to carry those terms honestly, and shows your ATS match score before and after so you can see what the changes bought you. Optimize against one posting at a time — a resume tuned to a single job outperforms a generically polished one, which is why the job description is required rather than optional.
What is a resume optimizer?
A resume optimizer compares your resume to a specific job description, finds missing keywords and experience signals, then helps rewrite your bullets so the resume matches the role without keyword stuffing. It is more action-oriented than a scanner because it helps fix the resume, not just diagnose it.
What does "optimizing" my resume actually change?
The optimizer reads your resume against a specific job description and does four things: a keyword gap report (the exact terms the posting wants that you are missing), a rewritten resume that works those keywords into real bullets, a cover-letter opening, and a list of your strongest hidden selling points for interviews. It tailors to one job at a time — that is what moves an ATS match score, not a generic polish.
Does it work for a CV as well as a resume?
Yes. Whether you call it a resume or a CV, ATS parsing depends on structure and keyword match, not the label. Paste either and the optimizer works the same way.
How is this different from a resume builder?
A builder helps you format a resume from scratch. An optimizer takes a resume you already have and tunes it to a specific job — closing keyword gaps and strengthening weak bullets. If you want to compare full tools, see our roundup of the best resume optimizer tools; if you just want yours fixed for the job in front of you, use this.
How is a resume optimizer different from a resume checker or scanner?
A checker or scanner tells you what may be wrong: missing keywords, formatting risks, or a weak score. A resume optimizer goes further by rewriting the resume for the target job, then showing how the match changed. Use the checker for a fast diagnosis; use the optimizer when you want a job-specific draft to submit.
Will recruiters be able to tell it was AI-optimized?
The optimizer keeps your real experience and voice — it surfaces and sharpens what is already true, weaving in the posting’s language naturally rather than padding with buzzwords. You should always review the output, but it reads as a tighter version of your own resume, not a generic AI draft.
