Your resume
Used to detect when your cover letter just repeats what's already there, and flag it as low complement value.

What it reads
A cover letter is read next to your resume and the posting, so it is scored against both.
Used to detect when your cover letter just repeats what's already there, and flag it as low complement value.
Scored across 5 dimensions: ATS keywords, complement value, opening hook, tone match, and personalization.
Provides the keyword target and the tone and culture signals your cover letter needs to match.
What it checks
Which job description keywords are present in your cover letter and which are missing. Shows redundant keywords already covered in your resume.
Whether the letter says anything your resume does not: motivation, company context, facts. A letter that repeats your bullet points scores low.
Scores your first 2–3 sentences. "I am excited to apply" scores 0. A specific, energetic, company-aware opener scores high.
Compares your writing register with the tone of the posting. A stiff letter for a casual startup posting gets flagged.
Detects generic phrases like "I am a highly motivated professional" and measures how specific the letter is to this company and role.
Once scored, subscribers get an AI rewrite that injects missing keywords, rewrites the opening hook, removes boilerplate, and matches the tone.

Common questions
Many ATS platforms store the cover letter with the application; whether its text is searched depends on the platform and how the employer set it up. A cover letter that mirrors the language of the job description is worth it either way, because the recruiter who opens it reads that language.
A score of 70 or above across all five dimensions is strong. Scores below 60, especially on complement and personalization, indicate the letter is too generic to make an impact.
Focus on skills, tools, and role-specific language from the job description that are not already heavily covered in your resume. Your cover letter should add new keywords, not just repeat what is already on the page.
Jobscan scores your cover letter against the job description in isolation. This tool performs a three-way analysis of resume, cover letter and job description together, so you can see if your cover letter adds value or just repeats your resume. The complement score and redundancy analysis are unique here.
