Finding the gaps in your resume, the short guide
How it works here
Your resume is compared against up to five job descriptions, and you get the skills they keep asking for that your resume never mentions, with the exact line from each posting as proof. Everything runs in your browser: your resume never leaves your device, and nothing is uploaded or stored. One finished check uses one action.
Compare like with like
Use postings for the same kind of role. Mixing five unrelated jobs produces a gap list for a job that does not exist, and tailoring toward it helps with none of them.
Patterns before hobbies
A skill appearing in four of five postings is a pattern worth your effort. A skill in exactly one is that hiring manager's hobby. Work the list in that order and stop when the patterns run out.
