How are Perplexity and ChatGPT similar?
Despite their differences, both tools overlap in what they can do for HR:
Both are AI-powered assistants capable of answering HR-related questions. They can serve as HR support tools for addressing employee questions or creating materials for training and development.
Additionally, both can summarize content, generate responses, and speed up workflows. For example, Perplexity can help draft job descriptions, summarize HR reports, or address compliance queries. Similarly, ChatGPT can assist in writing job posts, interview guides, HR communications, and policy summaries.
At the same time, both tools support natural language input and everyday questions in plain English without requiring technical commands, thereby reducing the learning curve.
What are the challenges of using Perplexity and ChatGPT for HR?
While there are many benefits in using Perplexity and ChatGPT, it’s not without its challenges, such as:
- Accuracy: One of the biggest risks in using Perplexity or ChatGPT is accuracy. ChatGPT may hallucinate, while Perplexity may pull incorrect or biased sources (e.g., ChatGPT may generate a DEI policy that references an outdated EEOC guideline).
- Data privacy: GenAI tools don’t protect sensitive HR data. For instance, copying a termination letter draft with employee details on ChatGPT — or uploading candidate résumés on Perplexity for quick comparison — could lead to compliance breaches.
- Lack of context: AI tools don’t know your company’s policies or culture unless you tell them. A job description draft may ignore your DEIB commitments or internal salary bands, unless you explicitly state those details in the prompt.
- Compliance concerns: Compliance leaders face heightened risk in fast-changing environments, and AI-generated suggestions may not align with legal or ethical standards. This means you must cross-check AI-generated policies against current regulations.

Skills needed to use Perplexity and ChatGPT more effectively
Here are some crucial skills HR professionals should have and develop in order to use both platforms more effectively:
- Basic AI knowledge: At a minimum, HR team members should understand the capabilities and limitations of large language models (LLMs). For instance, knowing ChatGPT might generate outdated statistics helps you verify sources.
- Prompt design: Clear, specific prompts lead to better AI outputs. For instance, instead of asking, “Write me a job ad,” you could prompt, “Draft a job posting for a Payroll Administrator in the U.S., with emphasis on compliance and pay transparency.”
- Hands‑on tool use: Learn to use both tools in HR workflows to help identify which is better when performing research or drafting content. You can use Perplexity to pull real-time salary data, then use ChatGPT to draft a compensation memo.
- AI strategy and adoption: Align AI adoption with company goals, workforce planning, and compliance requirements. You can create an internal HR policy that defines when to use GenAI tools and when to review their content.
- Critical thinking and judgment: Review AI output to ensure it’s free from errors. You can use ChatGPT to craft remote work policies, but you must cross-reference the information it generates with local regulations before including it in the employee handbook.
- Ethical awareness: Ensure AI-generated content doesn’t introduce bias or violate privacy. For example, review AI-drafted interview questions for potential discrimination, and refine them before using them.

How to use Perplexity in HR
Here are practical, hands-on examples of how you can use Perplexity in different HR scenarios, such as:
Research labor laws or HR trends with citations
Perplexity can help you stay on top of compliance by quickly finding updated legal requirements without having to sift through multiple websites. You can prompt Perplexity with queries like “latest changes in FMLA 2025” or “remote work legislation by state”, and receive replies with accurate, reliable citations and references.
Create quick FAQ for employee questions using up-to-date info
You can build a central FAQ to answer common questions using the latest legal updates and company policies. By prompting Perplexity for summaries of new regulations, you can quickly adapt responses to your company’s context and include source links for transparency. This saves time, ensures consistency, reduces repeated inquiries, and maintains compliance.
Benchmark HR policies using public sources
Perplexity can help you compare your policies against current practices in similar industries by pulling from publicly available sources. Queries like “best remote work policies 2025” or “competitive parental leave benefits” give quick insights into what competitors offer. You can then adapt these findings to strengthen your own policies.
Draft reference materials by pulling links and summaries
Perplexity can quickly generate summaries and gather source links that your HR team can use to create internal guides, policy overviews, or communication templates. By including citations, these materials remain transparent and easy to verify, helping your team share accurate, trustworthy information across the organization.
Analyze employee sentiment using external data
You can use Perplexity to help your HR team monitor workplace trends or employee experience benchmarks by pulling insights from surveys, studies, and industry reports. Example prompts your team can use include “employee engagement trends in the tech sector 2025” or “global employee turnover rates by industry 2025”.
Support learning and development with curated resources
Support L&D by using Perplexity to gather relevant training materials, case studies, or best practices to recommend to managers or employees. Example prompts include “effective leadership training case studies”, “best practices for hybrid workforce training 2025”, or “successful onboarding program examples in financial services”.
Prepare for talent acquisition discussions
Use Perplexity to gather current market insights, salary benchmarks, and hiring trends to support your organization’s recruitment strategy. Example prompts include “average compensation for data analysts in New York 2025”, “top recruitment channels for software engineers 2025”, or “emerging job roles in the renewable energy sector”.
How to use ChatGPT in HR
Below are practical, hands-on examples of using ChatGPT applicable in real-life HR scenarios, such as:
Generate job descriptions, onboarding documents, or HR memos
Your HR team can save hours by asking ChatGPT to draft first versions of job descriptions, onboarding checklists, or HR memos. They can do so by feeding ChatGPT a role title and required skills, and get a draft job description within seconds.
Draft interview questions or performance review templates
With the right prompts, ChatGPT can generate competency-based interview questions tailored to the role. For example, a Recruiter can prompt the tool to create role-specific interview questions for a Sales Manager position. It can also draft performance review templates aligned with your company’s competency model.
Translate HR policy into employee-friendly language
Legalistic HR policies often confuse employees. You can use ChatGPT to reframe them in plain language that all employees can easily understand. This is especially useful for compliance updates, where clarity is essential. For example, you can prompt ChatGPT to rewrite a data protection policy into a one-page FAQ, or explain parental leave eligibility using simple terms.
Role-play HR scenarios for training (e.g., conflict resolution)
ChatGPT can simulate HR scenarios for training and coaching purposes. HR leaders can role-play difficult conversations, such as conflict resolution or delivering feedback, using ChatGPT as the opposing party. This creates a safe space to practice sensitive interactions.
Summarize long HR documents
From 50-page handbooks to research reports, ChatGPT can pull out and highlight the main points and actions. Summaries enable HR professionals to quickly brief leaders or employees without needing to go through everything in detail. For instance, you can summarize annual employee survey results, or condense a government labor regulation update into bullet points.
Create personalized employee communications
ChatGPT can help draft tailored messages for different employee groups. For example, your HR team can prompt it to write separate communications for interns, managers, and executives about the same policy change, matching the tone of voice and writing to each audience’s preferences.
Assist in drafting DEI initiatives
HR teams can use ChatGPT to brainstorm DEI program ideas, generate inclusive language for job postings, or create awareness materials. For example, prompting it with “write inclusive job posting language for a software engineer role” can help reduce bias in hiring.

Perplexity vs ChatGPT: How to decide which to use in HR?
Both tools are useful, but their strengths differ. Perplexity is best for quick, sourced research and fact-checking — such as checking the latest overtime laws or gathering citations for compliance documents.
ChatGPT is better for generating ideas and content and for nuanced communication. It can brainstorm recruitment campaigns, draft engaging employee emails, or simulate HR conversations like conflict resolution.
For compliance-heavy environments, Perplexity offers stronger support through real-time search and citations, while ChatGPT shines in creative, people-focused communication. However, many HR teams use both — Perplexity validates the facts, while ChatGPT translates them into clear, professional HR materials.
Next steps
Perplexity is ideal for real-time, sourced research that supports compliance and policy work. ChatGPT, on the other hand, excels at producing creative, people-facing outputs like job descriptions, emails, or training scripts. Used together, they can cut admin work, improve accuracy, and free HR to focus on strategy.
Start small and build from there. Pilot one or two simple use cases, like using Perplexity to validate policy updates and ChatGPT to turn them into plain-language employee memos. Assess how well each tool integrates with your existing platforms, then compare results and scale based on what adds the most value to your HR function.
