One of my most used prompts when working with AI is “rewrite this…” and I know I’m not alone. It’s a simple, powerful prompt (that works way better when you provide more context like tone, length, style, and the target audience).

Back in February 2025, my fellow Ongig writer and general JD superstar, Heather Fenty, wrote this blog testing free GPT Job Description generators, including the AI job description generator from Ongig.

Fast-forward to July, and Ongig has rolled out its free AI Job Description Rewriter, and we couldn’t resist the chance to test it out and compare it to other GPTs in the store. 

So here it is: part two of our GPT testing series…The Battle of the JD Rewriters.

Job Description Rewriters GPTS

The first thing I noticed? A quick search of the GPT Store brought up resume rewriters, but only one JD rewriter. Great for job seekers trying to tailor their CVs to specific job postings, but not what we needed. The creative minds at Ongig were spot on: hiring teams, recruiters, and small business owners needed a purpose-built tool for rewriting job ads.

After a little more digging, I tracked down two more AI JD rewriter GPTs – and just like that, the battle was on.

Note: If you’re looking to make the entire job description creation process smoother – not just rewriting a single JD – our Text Analyzer might be worth a look. It’s designed to help you optimize, format, and fine-tune job postings efficiently while making them inclusive and engaging.

AI Job Description Rewriters I Tested

  1. Ongig’s AI Job Description Rewriter
  2. Job Description Rewriter by Jason A. Weiss
  3. Recruiter Assistant by Casey K Neese
  4. JD Automation Enhancer by Leading Knowledge Ltd.

All four claim to help improve or rewrite job descriptions using the power of AI.

How I Evaluated the AI Job Description Rewriters

For added fun and to keep things fair, I used the same evaluation criteria from Heather’s original blog article, and used the ‘winning’ output from those generators (the one Ongig’s Text Analyzer gave the highest total score to). The original was strong, but I was curious how each AI would elevate it. Here’s the original JD output to be tested:

For the final step I ran the rewrites through Ongig’s Text Analyzer to see how they performed on inclusivity and readability, just like in the original test. And more importantly, to see if there was an improvement. In case you (still) haven’t read the original blog, the testing criteria are below:

  • Ease of Use – Was the tool straightforward to launch and interact with, or did it require a complicated setup to get a result?
  • Speed – How quickly did it generate a usable job description? Was it near-instant, or did it feel slow and clunky?
  • Output Quality – Did the final rewrite feel polished, engaging, and professional – or did it read like generic AI filler?
  • Customization Options – Could I guide the output with tone, length, or structure preferences, or was it a one-size-fits-all result?
  • Inclusivity & Bias – Did it proactively avoid biased terms and reflect inclusive, welcoming language, or would I need to manually clean that up?
  • Grammar & Readability – Were the sentences smooth, scannable, and typo-free, or did they need significant editing?
  • Text Analyzer Score – Most importantly: Did the rewritten JD improve the score in Ongig’s Text Analyzer? This score helps quantify how inclusive, readable, and effective the job description really is.

#1: AI Job Description Rewriter (from Ongig)

  • Made the JD more succinct and easy to scan through


Cons:

  • The three prompts are too long to fit into their bubbles, so you can’t read all of it, which might feel clunky

Further Tests for Specific Job Description Rewrites

Two of the four AI Job Description Rewriters were designed for specific rewriting tasks – the Job Description Rewriter by Jason A Weiss to produce rewrites with client confidentiality for recruiters, and the JD Automation Enhancer to produce rewrites with integrated AI tools and automations. To make the test a little more fair, I decided to see whether the other two rewriting tools could do these things as well. Let’s see the results:

Ongig’s AI Job Description Rewriter:

I gave the prompt: “rewrite this JD for agency recruiters without mentioning the company name.”
Output: “Here’s a rewritten version of the Marketing Manager job description — optimized for agency recruiters, written at a 6th–9th grade reading level, and in a friendly, direct voice…”

Text Analyzer Scores: 

Total Score: 82.7 (down from 83.4%)

Bias Ratio: 50% feminine-coded words (down from 73%)

Recruiter Assistant – Job Description Rewrites:

I gave the prompt: “rewrite this JD for agency recruiters without mentioning the company name.”
Output: “Sure! Below are two rewritten versions of your job description for agency recruiters to use, without mentioning the company name. Each version highlights growth potential, compelling responsibilities, and unique benefits — one formal and one with a more conversational, informal tone.”

Total Score: v1 71.4%/v2 75.3% (down from 83.4%)

Bias Ratio: v1 50% feminine-coded words/v2 76.8% feminine-coded words  (original 73%)

Exclusionary Words: v1 stakeholder/v2 none (none in original)

Adverb Score: v1 100%/v2 48.6/100 (original 100%)

Word Count: v1 309/v2 310 words (down from 401)

Readability Score: v1 77.8/100 (9th-grade reading level)/v2 100/100 (5th-grade reading level) (original 78/100)

I gave the prompt: “rewrite this JD with integrated AI tools and automation suggestions.”

Word Count: v1 325/v2 321 words (down from 401)

Readability Score: v1 47..5/100 (12th-grade reading level)/v2 100/100 (7th-grade reading level) (original 78/100)

How AI Job Description Rewriters Handle Inclusive Language

Today’s top candidates care about diversity, equity, and inclusion (DEI). A job description that reflects inclusive values can attract qualified applicants from broader backgrounds, while one with biased or outdated language may discourage top talent. So how did the GPT rewriters do?

Using Ongig’s Text Analyzer, I evaluated each output for inclusive phrasing and balanced tone.

  • Ongig’s AI Rewriter scored consistently high for inclusivity, with no exclusionary words and a strong balance of gender-coded language.
  • Recruiter Assistant (Conversational version) surpassed inclusion and went too far the other way, with 100% feminine-coded words, but a perfect readability score.
  • JD Automation Enhancer and Job Description Rewriter by Jason A. Weiss both dropped noticeably in gender balance and clarity, reinforcing their more generic tone.

Insight: The rewriters that offered tone customization and clear, humanlike phrasing also tended to score better for inclusivity. Using a tool like Ongig’s Text Analyzer flags biased language, and provides neutral replacements.

Gender Bias in Language: Where AI Rewriters Succeed (and Fall Short)

Reducing gender-coded language is one way to make job descriptions more inclusive. Feminine-coded words (like “collaborative” or “nurturing”) and masculine-coded words (like “driven” or “dominant”) can subtly influence who applies, or doesn’t.

Here’s how the GPTs performed: 

GPT ToolBias RatioNotable Shift from Original
Original73% feminineBaseline
Recruiter Assistant (v2)100% feminineLarge increase
Ongig Rewriter70% feminineSlight decrease
JD Automation Enhancer55% feminineLarge drop
Recruiter Assistant (v1)55% masculineShifted male-coded
Jason A. Weiss Rewriter54% feminineLarge drop

Takeaway: Tools that allow voice customization are more likely to produce gender-balanced results, but even the most inclusive outputs still need human review to catch unintentional shifts in tone.

Exclusionary Words: Subtle but Impactful

A truly inclusive job description avoids exclusionary or inaccessible terms. These words that may alienate or confuse candidates from non-corporate or non-traditional backgrounds.

Encouragingly, all tools avoided major exclusionary terms in their default rewrites. The only flagged words were:

  • “Stakeholders” — found in one version of Recruiter Assistant
  • “Lifting” — flagged in a secondary version of the same tool
  • “Hands-on” — found in a rewrite with automation prompts

Note: While these seem small, the cumulative impact of jargon and exclusivity can discourage applications. Tools like Ongig’s Text Analyzer help catch this early, and offer replacements.

Readability: Can Candidates Actually Understand It?

You might have the most comprehensive job description in the world, but if candidates can’t understand it, they won’t apply.

Using the Text Analyzer’s Readability Score, here’s how the tools stacked up:

GPT ToolReadability ScoreGrade Level
Original78/1008th grade
Ongig Rewriter100/1006th grade
Recruiter Assistant (v2)100/1006th grade
JD Automation Enhancer72.1/10010th grade
Jason A. Weiss Rewriter59.7/10011th grade
Recruiter Assistant (v1)72.5/10010th grade

Conclusion: Shorter, friendlier rewrites consistently improved readability. The best results came from tools that cut jargon and embraced conversational tone.

Word Count & Scannability: Shorter Isn’t Always Better

AI-generated content often trims word count, but did it help or hurt?

GPT ToolWord Count% Change vs. Original
Ongig (original)401
Ongig Rewriter345-14%
Recruiter Assistant (v2)318-21%
JD Automation Enhancer330-18%
Jason A. Weiss Rewriter309-23%

Takeaway: Tools that reduced fluff but preserved clarity scored highest. Ongig’s GPT struck the best balance between brevity and completeness, trimming without losing valuable detail.

Keyword Impact: Did It Support SEO?

Whether you’re posting to a job board or sharing on LinkedIn, using relevant keywords can improve visibility. Keywords relevant to the position you’re hiring for really matter.

Ongig’s AI Rewriter retained or reinforced essential keywords in every section, which helped boost discoverability.

Jason A. Weiss’s tool, focused on anonymization, removed many useful keywords, making it less SEO-friendly for public postings.

Tip: For SEO success, choose a rewriter that improves structure and tone without stripping away the language job seekers are actually searching for.

When Free AI Job Description Rewriters Fall Short

Free rewriting tools are a great way to test the power of AI in the job description creation process, but they do have limits. If you’re trying to attract qualified candidates for a specific role, you need more than just a quick rewrite.

Here’s where free AI job description rewriters often fall short:

Workflow Support

Most free tools don’t let you save, edit, or collaborate on job posts with your hiring team. There’s no real infrastructure to support HR professionals who need to generate multiple job descriptions across departments or locations.

Bias Detection

While a few tools attempt it, most free rewriters don’t flag exclusionary language, gender-coded words, or outdated terminology. This means your job description templates might still need a DEI pass before they’re ready to attract the right candidates.

Scalability

If you’re writing job descriptions for multiple job titles, across different departments – from marketing teams to engineering roles – you need a tool that scales. Most free tools aren’t built for that kind of complexity.

What Paid Tools Like Ongig’s Text Analyzer Offer

Paid platforms like Ongig’s Text Analyzer are designed to do more than just spit out AI content. They’re built for real-time collaboration, accurate job descriptions, and true alignment with your company’s voice and hiring goals.

Here’s what sets it apart:

  • Generate comprehensive job descriptions that are inclusive, branded, and easy to scan
  • Optimize for SEO with the right keywords and structure to boost visibility on job boards
  • Flag biases, exclusionary terms, and compliance gaps, and provide replacement suggestions
  • Support a team-wide hiring process with shared access and version control
  • Customize job descriptions to fit your specific position, tone, and company culture
  • Provide suggestions for key responsibilities, job skills, and necessary qualifications
  • Enable bulk editing and syncing with your ATS
  • Store original content, approved templates, and job responsibility generators in one place
  • Highlight missing job requirements, basic information, or legal compliance issues
  • Integrate easily with your existing tools – whether you’re a global enterprise or a small business owner

If you’re serious about writing high-quality job descriptions that support your DEI goals and streamline your recruiting, a solution like Ongig’s Text Analyzer can turn a basic rewrite into a powerful hiring asset.

Where to Try the AI Job Description Rewriters I Tested

If you want to explore the tools I used in this test, you can try them out with a free account on ChatGPT:

Each one uses advanced AI models to help with writing style, formatting, and tone, though results vary. Whether you’re hiring for a new role or just want to rewrite a lengthy content block into a concise summary, these AI description generators can be a helpful starting point.

Best Use Cases for AI Job Description Rewriters

Based on my testing, here are the best use cases for AI-powered job description tools made for rewriting:

  • Quick rewrites when your JD is mostly complete but needs clarity, tone, or other improvements
  • Bulk editing for consistency across similar roles – be ready to provide sturdy prompts to receive consistent outputs
  • Improving readability and removing jargon
  • Optimizing content for posting to job boards, career pages, and social media
  • Creating custom JDs for different audiences (internal, public, or confidential recruiter versions)
  • Drafting application process details, job summaries, and bulleted lists of key skills
  • Enhancing product descriptions or department overviews for specific positions

Free tools offer a simple, single-click way to get started, but for more control, clarity, and compliance with industry standards, you’ll likely need something more robust.

Should You Use Free AI Job Description Rewriters?

The short answer is yes, especially if you’re just getting started or need help translating rough notes into a complete job description. These tools are perfect for creating detailed summaries, position overviews, and entry-level templates without investing much time.

But for hiring success, accuracy, SEO optimization, and team-wide use, free GPTs alone won’t cut it. They won’t check for legal requirements, integrate with your resume builder, or offer customer support. And they certainly won’t align everything with your company’s needs and brand tone.

If your goal is to attract your ideal candidate, land more job applications, and ensure you’re providing clear expectations for your next dream job hire, then combining AI with a professional editing process is the easy way to get there.

Why I Wrote This

AI can make writing job descriptions easier, faster, and more inclusive, but not all tools are created equal. Some GPTs are great for concise summaries or removing filler. Others miss the mark when it comes to bias, readability, or SEO.

If you’re relying on a free job description generator, it’s worth understanding the tradeoffs.

And if you want to go further – improving content quality, reducing bias, aligning with your work environment, and scaling JD creation across your team – check out what we’re building at Ongig.

We believe in the power of AI, but also in the importance of human oversight, strategy, and clear communication. Tools like the Text Analyzer exist to give you all three.
