Head-to-Head Test: Same Prompt, Both AIs

I gave both AI tools the identical prompt:

Write a professional resume in Markdown for a Product Manager with 5 years of experience.

Background:
- Current: Senior PM at B2B SaaS startup (2022-present)
- Previous: PM at mid-size tech company (2020-2022)
- Education: BS Computer Science

Key achievements:
- Launched new product line
- Managed team of 3 designers and 4 engineers
- Improved customer retention

Include: professional summary, experience with achievement bullets, skills section.
Format in Markdown.

ChatGPT's Response (summarized)

## Professional Summary
Data-driven Product Manager with 5+ years of experience launching successful B2B SaaS products. Proven track record of driving 40% improvement in customer retention and leading cross-functional teams of 7+. Skilled in agile methodologies, user research, and product analytics.

## Experience

### Senior Product Manager | TechStartup Inc
*2022 - Present*

- Spearheaded launch of new product line generating $2M ARR in first year
- Led cross-functional team of 7 (3 designers, 4 engineers) to deliver features 20% ahead of schedule
- Implemented customer feedback loops resulting in 40% improvement in NPS scores
- Reduced customer churn by 25% through data-driven feature prioritization

Claude's Response (summarized)

## Professional Summary
Product Manager with five years of experience building and scaling B2B software products. I've launched new product lines from concept to market, managed small but effective cross-functional teams, and focused heavily on retention—because keeping customers matters as much as acquiring them.

## Experience

### Senior Product Manager | B2B SaaS Startup
*2022 - Present*

- Took a new product line from initial concept to market launch, building the roadmap, running customer discovery, and coordinating across engineering and design
- Managed a team of 3 designers and 4 engineers, establishing planning rituals and removing blockers to keep shipping velocity high
- Led a retention initiative that identified why customers were churning and prioritized fixes, improving retention measurably (you should add your specific metrics here)

Key Differences

ChatGPT:

• Immediately adds metrics (even estimated ones)
• More aggressive, sales-y tone
• Uses industry keywords heavily ("cross-functional," "data-driven," "agile")
• Produces polished, ready-to-use bullets

Claude:

• More natural, conversational tone
• Honest about where you need to add your own data
• Less likely to invent metrics
• Asks you to fill in specifics

Detailed Comparison by Task

Task 1: Writing Achievement-Focused Bullets

ChatGPT excels here.

In our testing, ChatGPT tends to be punchy and metric-forward. It naturally transforms responsibilities into achievements and adds quantification.

Example bullet transformation:

Input: "I managed the engineering team"

ChatGPT: "Led 8-person engineering team to deliver 15 features across 4 quarterly releases, maintaining 95% on-time delivery rate"

Claude: "Managed an engineering team of eight, focusing on clear communication, reasonable sprint planning, and creating an environment where people could do their best work"

ChatGPT gives you interview-ready bullets. Claude gives you more human-sounding narrative—great for certain roles, but may need tightening for traditional resumes.

Task 2: Following Complex Instructions

Claude excels here.

When prompts get complex ("include these 5 things, avoid these 3 things, match this job description"), Claude follows instructions more precisely.

Example:

Prompt: "Write a summary that mentions Python, doesn't use the word 'passionate,' and references B2B experience."

ChatGPT sometimes misses constraints or adds "passionate" anyway. Claude follows the ruleset carefully.

Task 3: Industry-Specific Language

ChatGPT has an edge.

ChatGPT picked up more industry jargon from its training data. Tell it you're a PM, and it knows "OKRs," "sprint velocity," "product-market fit." Tell it you're in finance, and it knows "DCF," "LBO," "covenant compliance."

Claude is solid but occasionally uses slightly less precise industry terms.

Task 4: Avoiding "AI-Sounding" Writing

Claude is clearly better.

ChatGPT loves certain phrases:

• "Spearheaded"
• "Leveraged"
• "Results-driven"
• "Cross-functional"

These are fine in moderation but can make your resume feel AI-generated. Claude writes more naturally and is less likely to repeat the same phrases.

Task 5: Honest Feedback

Claude is much more helpful here.

Ask ChatGPT to critique your resume, and it often gives generic positive feedback with soft suggestions.

Ask Claude, and it will tell you directly: "Your third bullet is vague—you say you 'improved performance' but don't explain how or by how much. That won't stand out."

If you want honest editing, Claude is the better choice.

Best Prompts for Each AI

Best ChatGPT Prompts

For punchy bullets:

Transform these responsibilities into achievement-focused resume bullets with specific metrics:

[YOUR TEXT]

Use strong action verbs. Include numbers for everything (estimate if needed). Keep each bullet to one line.

For keyword optimization:

Here's my resume and a job description. Add keywords from the job description naturally into my resume without changing the meaning of my achievements.

Resume: [YOUR RESUME]
Job Description: [JD]

Best Claude Prompts

For natural-sounding writing:

Rewrite my resume summary so it sounds like a confident professional wrote it—not like AI generated it. Avoid clichés like "passionate," "results-driven," or "leveraged."

Current summary: [YOUR SUMMARY]

For honest critique:

Review this resume as if you were a hiring manager who's seen 500 resumes today. Be honest about what's weak, what doesn't stand out, and what I should change. Don't sugarcoat it.

[YOUR RESUME]

For complex formatting:

Create a resume with these exact specifications:
- Summary: 2 sentences max
- Experience: Last 3 jobs only, 4 bullets each
- Skills: Grouped into Technical, Tools, and Methods
- No generic phrases
- Markdown format

Background: [YOUR INFO]

When to Use Each AI

Use ChatGPT When:

• You need metric-heavy, punchy bullets fast
• You're in a traditional industry that expects specific keywords
• You want "interview-ready" content with less editing
• You're optimizing for ATS keyword matching
• Speed matters more than nuance

Use Claude When:

• You want natural-sounding writing that doesn't feel AI-generated
• You need honest feedback on what's not working
• Your instructions are complex with many constraints
• You're in a role where voice/tone matters (creative, leadership, communications)
• You want help thinking through your positioning, not just words

The Real Workflow: Using Both

Here's the power move: use both.

Step 1: Draft with ChatGPT

ChatGPT's strength is generating solid first drafts quickly. Get your foundation.

Write a professional resume in Markdown for a [ROLE] with [X] years experience.

[YOUR BACKGROUND]

Include quantified achievements and strong action verbs.

Step 2: Refine with Claude

Take ChatGPT's output to Claude for critique and refinement.

Here's a resume I'm working on. Review it for:
1. Anything that sounds too AI-generated or clichéd
2. Weak bullets that don't demonstrate impact
3. Missing information that would make me stand out
4. Tone and voice consistency

Be honest and specific with feedback.

Step 3: Design with ResumeMD

Both AIs give you Markdown. Neither gives you design.

Paste your final content into ResumeMD to turn it into a professional, ATS-friendly PDF.

This three-step workflow—ChatGPT for drafting, Claude for refinement, ResumeMD for design—produces better results than any single tool alone.

---

What Neither AI Can Do

Both ChatGPT and Claude share the same limitation:

They can't design your resume.

Both output text. Great text, but text.

You still need:

• Professional templates
• Proper formatting
• ATS-compatible PDF export
• Visual hierarchy

That's why ResumeMD exists. It's the design layer for AI-generated content.

• Paste Markdown from either AI
• Pick from 32 professional templates
• Export polished, ATS-friendly PDF
• Done in 60 seconds

Your AI-generated content deserves professional presentation.

Conclusion: The Best AI for Resumes

There's no wrong choice. Both ChatGPT and Claude produce excellent resume content.

• ChatGPT: Better for metrics, keywords, punchy bullets
• Claude: Better for natural writing, honest feedback, complex instructions

The real workflow is:

1. AI generates content (either works)
2. You verify and edit (always necessary)
3. ResumeMD handles design (essential step)

Stop debating which AI is better. Start the process.

Your resume is 5 minutes away.
