プロンプト
履歴書をATS通過に最適化する

Target job posting: [paste the full job description] My current resume: [paste your full resume text] Industry: [your industry] Optimize for ATS: 1. Identify keywords from the job description that are missing from my resume 2. Suggest where to naturally incorporate each missing keyword 3. Flag any formatting issues that ATS systems commonly reject (tables, columns, graphics, headers) 4. Recommend a clean, ATS-friendly format structure 5. Check that my job titles, dates, and education are in standard ATS-readable format 6. Score my current resume's ATS compatibility on a 1-10 scale with specific improvements

テスト済み Feb 15, 2026
プロのコツ
シンプルなフォーマットを使いましょう。テーブル、カラム、グラフィックスはATSが正しく解析できません。プレーンなテキストが最もATSフレンドリーです。
履歴書の箇条書きをインパクトのある実績に変換する
Help me transform my resume bullet points from duties to accomplishments. My current bullet points: [paste 8-12 current bullets from your resume] Role these are for: [job title] Industry context: [your industry] Metrics I can access: [revenue, users, time saved, cost reduced, team size, etc.] Transform my bullets: 1. Rewrite each bullet using the formula: [Action Verb] + [What You Did] + [Measurable Result] 2. Add specific numbers, percentages, or dollar amounts to every bullet possible 3. Replace passive language with powerful action verbs 4. Remove generic phrases like "responsible for" and "helped with" 5. Prioritize bullets by impact — strongest accomplishment first 6. Ensure each bullet can stand alone and tells a complete micro-story

効果的な職務経歴書の要約を書く
Help me write a professional summary for the top of my resume. Target role: [job title I'm applying for] Years of experience: [number] Key skills: [list 5-7 top skills] Biggest career achievement: [one standout accomplishment] What makes me different: [unique value proposition] Industry: [your industry] Write my summary: 1. Craft a 3-4 sentence summary that immediately communicates my value 2. Include the target role title and years of experience naturally 3. Weave in 3-4 keywords from typical job descriptions for this role 4. Lead with my strongest differentiator, not generic qualifications 5. Provide 3 alternative versions (confident, results-focused, narrative) 6. Keep it under 50 words — recruiters don't read paragraph summaries

Identify the 5 strongest transferable skills and how to frame them for the new industry 2. Rewrite my job descriptions using language from the target industry 3. Suggest a functional or hybrid resume format that emphasizes skills over chronology 4. Create a "bridge statement" that explains my career pivot positively 5.

Help me address gaps in my employment history on my resume. Gap periods: [list each gap with dates] Actual reasons: [be honest — layoff, health, caregiving, travel, personal, etc.] What I did during each gap: [any activities, learning, volunteering, freelancing] How I feel about the gaps: [confident / embarrassed / nervous] Target role: [what I'm applying for now] Address my gaps: 1.

Match my skills against the job requirements and rank by relevance 2. Identify must-include skills that the job description mentions explicitly 3. Suggest skills to remove (irrelevant or potentially harmful to include) 4. Organize skills into logical categories (Technical, Leadership, Tools, etc.) 5. Recommend proficiency indicators if the role warrants them 6. Identify skills the job description implies but doesn't state directly

結果元: GPT-4o · テスト済み Feb 15, 2026Claude
Excels at transforming weak bullets into compelling accomplishments and crafting career pivot narratives. Best at making resume language sound authentic rather than template-generated.
結果元: Claude 3.5 Sonnet · テスト済み Feb 15, 2026Grok
Writes the punchiest, most impactful resume bullet points with strong action verbs that grab attention. Strips out corporate fluff and gets straight to what makes you impressive. Less suited for conservative industries where formal, traditional resume language is expected.
結果元: Grok 2 · テスト済み Feb 15, 2026Your resume is a marketing document, not a biography. Include only what's relevant to the job you want, not everything you've ever done. Every bullet point should answer the question: 'Does this make the hiring manager want to interview me?'
One resume does not fit all jobs. Maintain a master resume with all your experience, then create tailored versions for each application. The 15 minutes spent customizing is the difference between the maybe pile and the interview pile.
Numbers are your resume's best friend. Quantify everything you can: revenue generated, time saved, team size managed, percentage improvements. 'Increased sales by 23%' is infinitely more powerful than 'Helped increase sales.'
