According to SHRM, nearly two-thirds of organizations use AI to generate job descriptions. At the same time, another 40% use it to customize their job postings further and attract target groups more effectively.
Are all AI tools the same? Can they really handle the nuance of job descriptions?
We decided to use 3 of today’s most talked-about AI tools —ChatGPT, Gemini, and Perplexity — to rewrite job descriptions for the same role.
Our goal: Determine which one actually makes a JD more transparent, inclusive, and candidate-friendly.
Methodology
For this experiment, we picked BetterTeam’s ‘Digital Marketing Manager’ job description:

You’ll work closely with your team to plan and run online campaigns, manage our social media pages, and track how well things are working. Your ideas and strategies will help us improve and grow.

- Great communicator and team player
- Curious and open to learning new tools and trends
What We Value

- New ideas and teamwork
- A focus on results and continuous improvement
- A respectful and inclusive work environment
We welcome applicants of all backgrounds, abilities, and experiences. If you meet some—but not all—of the listed requirements, we still encourage you to apply.
Analysis:
ChatGPT did a great job in inclusivity. It included an explicit welcoming statement for diverse applicants. It replaced rigid requirements with “or equivalent experience” language. It included the sentence: “If you meet some—but not all—of the listed requirements, we still encourage you to apply.” It added a “What We Value” section emphasizing respect and inclusion.
ChatGPT also sounds more approachable by swapping “We are searching for” with
“We’re looking for”.
In terms of tone, it missed the mark. Grammarly scored the JD at a 9th-grade level (59), not an 8th-grade level as instructed. Some of the sentences are longer than necessary. The JD could also switch simpler words like ‘equivalent experience’ for ‘similar experience’.
Gemini
Digital Marketing Leader
We’re looking for an inventive and experienced leader to head up our marketing team.
In this role, you will be in charge of all parts of our marketing work. Your main goal will be to help our company become better known in the area and to make more people love and trust our brand.
What You’ll Do:
Your job will include creating, starting, and checking on our online marketing campaigns across all digital platforms. We are looking for someone with experience in marketing, creative design, and running social media.
Besides being a great communicator, you’ll also be able to work well with others and use data to solve problems.
Key Responsibilities:
- Plan and manage all parts of our online marketing. This includes our customer contact list, email, and online ads.
- Create and keep an eye on the budget for all marketing campaigns.
- Plan and manage what we post on our social media platforms.
- Write clear reports on how well our marketing campaigns are working.
- Work with advertising and media specialists to make our marketing better.
- Find the newest trends and technology that affect our business.
- Look at important numbers that show how many people visit our website, how many sales we make, and who our customers are.
- Work with your team to come up with new and creative ways to grow.
- Manage all contests, giveaways, and other online projects.
What You’ll Bring:
The skills and experience below are a good guide. We encourage you to apply even if you don’t meet every item listed, especially if you have experience that you think makes you a great fit.
Desired Experience and Skills:
- Experience in digital marketing or advertising.
- Strong understanding of social media platforms, their best ways to work, and how to read website reports.
- Good understanding of web languages like HTML, CSS, and JavaScript.
- A creative mind and strong skills in looking at data to find solutions.
- Excellent communication and people skills.
- Know the latest trends and technology in online marketing.
Analysis:
Gemini achieved the 8th-grade target by having a readability score of 65. It also uses simpler, more direct language like “keep an eye on” instead of “monitor,” “come up with” instead of “develop”.
For inclusivity, it included an excellent qualifying statement: “We encourage you to apply even if you don’t meet every item listed, especially if you have experience that you think makes you a great fit”. It removed the rigid “Bachelor’s degree” requirement entirely, focusing solely on experience. It also removed the “minimum 5 years” barrier.
However, Gemini’s JD rewrite produced lower-quality writing: Grammarly score of 83/100 vs ChatGPT’s 98/100. This suggests problems in grammar, phrasing, and overall clarity. It’s too wordy: “their best ways to work” should be swapped with “best practices,” and “how to read website reports” should be replaced with “analytics”. There’s also a disorganized structure by adding ‘What you’ll do’ and “What you’ll bring’ when ‘Key Responsibilities’ and ‘Desired Experience and Skills’ would be enough.
Another concern would be replacing the job title “Digital Marketing Manager” with “Digital Marketing Leader”. While “leader” is more inclusive than “manager,” changing the job title wasn’t requested and could cause confusion.
Perplexity
Digital Marketing Manager
We are looking for a creative Digital Marketing Manager to lead our marketing team. In this role, you will help grow our brand’s presence and build strong connections with our customers.
You will plan, run, and track digital marketing campaigns across different online platforms. We are looking for someone with experience in marketing, social media, and working with creative teams. You should be a clear communicator and good at working with others and analyzing data.
What You Will Do:
- Manage all parts of our digital marketing, including email and online ads.
- Create and control budgets for marketing campaigns.
- Oversee our social media channels.
- Prepare clear reports on how marketing campaigns are doing.
- Work with advertising and media partners to improve results.
- Keep up with new trends and tools in digital marketing.
- Check important data like website visits and audience information.
- Work with the team to come up with new ideas to grow our business.
- Lead contests, giveaways, and other online projects.
What We Are Looking For:
- A bachelor’s degree in marketing or a related field.
- At least 5 years of experience in digital marketing or advertising.
- Good knowledge of social media platforms, best practices, and website analytics.
- Basic understanding of HTML, CSS, and JavaScript.
- Creative and able to analyze data well.
- Strong communication skills and able to work well with others.
- Always learning about the latest digital marketing tools and trends.
Analysis:
Just like Gemini, Perplexity achieved the 8th-grade target with a readability score of 65. Clean writing using straightforward words and phrases (no fluff!). Professional yet accessible tone. Well-organized sections with clear headers. It also stayed closest to the original job description structure.
However, inclusivity is a MAJOR problem. Gender Decoder flagged several words in the job description as masculine-coded: lead, analyze, analytics, and analyzing. Such words “risks putting women off applying”, as per research. This JD requires a rewrite to make it “more inclusive and bias-free”.
What the Data Shows
For overall task completions, ChatGPT won. The JD it rewrote showed the best balance of quality, inclusivity, and structure. It only missed the reading level.
In terms of inclusivity, Gemini removed most barriers. It also has the most welcoming tone. ChatGPT also demonstrated strong explicit inclusion statements. On the other hand, Perplexity actually rewrote JD to be less inclusive than the original (masculine-coded).
Among all the AI software, Gemini’s JD is the most readable (achieving a score of 65), followed by Perplexity (61) and ChatGPT (59). These readability scores can be attributed to how ‘polished’ the rewrite was: grammatically correct, consistent formatting, word choices, and sentence flow (smooth transitions, logical flow). So ChatGPT felt most refined and error-free. Gemini had awkward phrases like “their best ways to work”. Perplexity was clear but repetitive (34% unique words).
In general, we saw a trade-off between clarity and accuracy across tools. The clearer the JD, the more detail got stripped away. The more corporate the JD, the less inclusive it felt.
AI can save time on editing, but recruiters still need to check AI-generated (or rewritten) job descriptions for technical accuracy, including inclusivity nuances.
Ongig POV
While standalone AI tools give you a draft, they don’t solve the biggest recruiter pain points: compliance, consistency, and scale. That’s where job description management software (JDMS) comes in.
More than just drafting and editing job descriptions, JDMS like Ongig allow recruiters to
- Create JD templates + version control at scale.
- Uncover biases on a deeper level, like veterans, elitism, neurodiversity, and even former felons.
- Automatically add required sections, such as EEO statements and salary, to comply with state and federal regulations.
- Access to dashboards to review job descriptions’ performance
- Integration into ATS and workflows
AI is helpful, but JDMS like Ongig ensures results recruiters can trust.
Why I wrote this
Our mini experiment showed that AI can save hours — but no tool nailed everything. Recruiters still need oversight, and organizations still need software designed for compliance and scale. That’s why we believe the future is AI-powered job description management software, not AI in isolation. Request a demo to see how it works.
FAQs
1. Can AI tools like ChatGPT, Gemini, and Perplexity really write job descriptions?
Yes. They can produce a solid first draft in seconds.
However, our experiment showed that each tool varies in quality and focus:
- ChatGPT: Best for inclusive, conversational copy.
- Gemini: Strong structure, but often too formal.
- Perplexity: Extremely readable but loses technical depth.
AI still requires human oversight for compliance, accuracy, and tone consistency.
2. Can recruiters rely on AI alone to create compliant job descriptions?
Not yet. While AI helps with tone and inclusivity, it doesn’t understand local labor laws or EEOC compliance. And that’s where job description management software (JDMS) becomes essential.
Ongig’s JDMS ensures every JD meets compliance standards, maintains consistent formatting, and aligns with brand tone at scale.
3. What’s the best way to use AI tools in the JD creation process?
Use AI as your first draft assistant, not your final editor.
Here’s a recommended workflow:
- Draft the JD with ChatGPT, Gemini, or Perplexity.
- Check readability and inclusivity using Ongig’s tools or other JDMS tools.
- Upload to your JDMS for compliance, formatting, and version control.
This way, recruiters save time and maintain quality, combining the speed of AI with the reliability of structured software.
