§ When to use this

Sending the same resume to every job is the fastest way to get filtered out by applicant tracking systems and unimpressed recruiters. Tailoring works, but doing it by hand for each posting is tedious and easy to fumble. This prompt runs a structured gap analysis: it pulls the real keywords and must-haves from the posting, then maps your resume against them so you can see exactly what's matched, partial, or missing. Crucially, it tells you how to close each gap honestly, by adding a real bullet, reframing existing experience, or leaving it alone rather than inventing skills you don't have. The match-readiness score gives you a quick gut check on whether a role is worth a heavy rewrite or a light touch. Use it before every serious application, especially for competitive roles where ATS keyword matching is the first hurdle. The tailored summary section it produces is often the single highest-impact edit, since it's the first thing a recruiter reads.

your prompt — fill the fields above
Act as an ATS and hiring expert. Compare my resume to a target job description and tell me exactly how to tailor it. My resume: [PASTE RESUME]. Job description: [PASTE JOB DESCRIPTION]. First, extract the top 10 keywords and must-have requirements from the posting. Then map each to where my resume already covers it, partially covers it, or misses it entirely. For matches, suggest the exact phrasing to mirror. For gaps, tell me whether to add a real bullet, reframe existing experience, or leave it (never fabricate). Finish with a tailored 3-sentence summary section and a match-readiness score out of 100 with the two highest-leverage edits.

§ Example Output

What you can expect back

Top keywords: HubSpot, A/B testing, SEO, campaign management, email marketing, analytics, cross-functional, SaaS, lead generation, reporting. Matched: email marketing, campaign management, analytics. Partial: A/B testing (you ran 'subject-line tests'; rename to 'A/B testing'), SEO (you optimized blog tags; make it explicit). Missing: HubSpot (you used Mailchimp; reframe as 'marketing automation platforms, transferable to HubSpot'); lead generation. Tailored summary: 'Data-driven marketer with 3 years running cross-functional email and social campaigns at a SaaS company. Skilled in marketing automation, A/B testing, and analytics-led optimization. Proven launch coordinator seeking to drive lead generation at scale.' Match-readiness: 72/100. Highest-leverage edits: add a lead-gen bullet and rename subject-line tests to A/B testing.

§ Pro Tips

Get sharper results

  • 01Paste the job description as plain text without the company's fluffy benefits section so the model focuses on real requirements.
  • 02If your score is under 60, the role may be a stretch; spend your energy on better-matched postings.
  • 03Apply the exact keyword phrasing the posting uses; ATS systems match strings, not synonyms.
  • 04Re-run after editing to confirm the gaps actually closed and the score moved.
§ Variations

Adapt it for your case

Cover-letter handoff

Append: 'Then list the three gaps I should proactively address in my cover letter.'

Interview prep

Ask it to turn each partial or missing requirement into a question you'll likely be asked, with a prep note.

Multi-role compare

Paste two job descriptions and ask which one your resume is closer to and why, to prioritize applications.

§ FAQ

Common questions

Is mirroring keywords just gaming the ATS?

No, you only mirror requirements you genuinely meet. The point is to phrase real experience in the words the system and recruiter are scanning for.

What does 'reframe' mean versus 'add'?

Reframe means rewording existing experience to match their language; add means writing a new bullet for real work you simply left off your resume.

Should I tailor for every single application?

For roles you care about, yes. For high-volume spray applications the score helps you decide where deeper tailoring is worth the time.
