The analyzer checks 18 structural sections, 100+ CS-specific metrics and KPIs (NPS, CSAT, churn, NRR, ARR), tool keywords (SuccessGuardian,Gainsight, ChurnZero, Salesforce, Zendesk), achievement metrics tied to real outcomes, ATS compatibility issues, passive-voice and weak-phrase patterns, CS lifecycle signal coverage (expansion, churn, onboarding, renewal, executive engagement), and industry domain context.

No. All analysis runs entirely in your browser using client-side JavaScript. Your resume text is never sent to a server, stored, or shared with any third party.

Scores of 75 and above indicate a strong CS resume with solid keyword coverage, quantified achievements, and proper structure. Scores between 50–74 suggest the resume has a solid foundation but needs targeted improvements — usually around quantification and CS-specific KPIs. Scores below 50 typically mean critical gaps in metrics, tool keywords, or ATS compatibility that need to be addressed before applying.

Achievement metrics (%, $, ×, account counts tied to outcomes) account for 25% of the total score because they are the #1 differentiator in CS resumes. Hiring managers and ATS systems look for concrete proof of impact: renewal rates, ARR managed, churn reduction percentages, TTV improvements, and expansion revenue generated. Generic task descriptions without numbers fail to convey the scope or quality of your work.

The highest-value keywords fall into three groups: (1) Metrics — NRR, GRR, NPS, CSAT, churn rate, renewal rate, ARR, MRR, TTV, health score, QBR, EBR; (2) Tools — SuccessGuardian, Gainsight, ChurnZero, Totango, Catalyst, Vitally, Planhat, Salesforce, Zendesk, HubSpot, Intercom; (3) Actions — onboarded, retained, renewed, expanded, championed, orchestrated, facilitated, de-escalated, scaled.

The analyzer extracts text from standard PDF files using PDF.js, which runs in the browser. Text-based PDFs from Google Docs, Microsoft Word, or standard resume builders work best. Scanned or image-only PDFs may not extract correctly — in that case, use the paste-text option to copy your resume text directly into the tool.

ATS (Applicant Tracking System) is the software most companies use to filter resumes before a human ever sees them. ATS systems struggle to parse tables, multi-column layouts, images, and certain formatting. The analyzer flags these issues so your resume can be read correctly by ATS software, increasing the chance it reaches a human reviewer.

Add numbers tied to real outcomes in every experience bullet: your renewal rate (e.g. 96%), ARR portfolio size (e.g. $3.2M), churn reduction (e.g. reduced logo churn from 14% to 6%), onboarding metrics (e.g. reduced TTV from 47 to 28 days), expansion ARR (e.g. generated $840K upsell revenue in FY23), and CSAT or NPS scores. Aim for 8–12 quantified results across your resume. Dates, phone numbers, and education grades do not count as achievement metrics.

The most damaging phrases in CS resumes are: 'responsible for', 'worked with', 'helped to', 'assisted with', 'results-driven', 'passionate about', 'strong communication skills', 'detail-oriented', 'team player', 'acted as', 'proactively managed' (without a specific outcome), 'handled', 'consistently', and 'in charge of'. Each of these hides your contribution behind vague language — replace them with strong action verbs followed by specific metrics.

The most effective CS resume bullets follow this structure: [Strong verb] + [what you did] + [scale or context] + [metric outcome] + [optional: how or why]. Example: 'Reduced logo churn from 14% to 6% across 38-account portfolio by launching a proactive health score intervention program, flagging at-risk accounts 45 days ahead of renewal.' This format immediately communicates scope, impact, and method.
