Is it legal to use ChatGPT to screen resumes?

It depends on where you hire and how the tool is used. Automated screening can trigger bias-audit and notice rules (New York City), notice rules (Illinois) and record-keeping rules (California), and it always falls under anti-discrimination law. Keep a human decision-maker.

Which AI tool is best for HR?

ChatGPT, Claude, Gemini and Microsoft Copilot all handle drafting well. Pick the one your company already approves for confidential data.

Can I use free AI tools for HR work?

Yes, for drafts that contain no personal or confidential data, if your company's policy allows it.

When does the Colorado AI law take effect?

The original Colorado AI Act (SB 24-205) never took effect. Its replacement, SB 26-189, signed in May 2026, takes effect January 1, 2027.

Can HR use ChatGPT for hiring?

By Andreas Henriksson · Updated November 15, 2026 · Law dates checked against the official sources listed at the end

Short answer: yes, for drafting and organizing work (job posts, interview guides, onboarding plans, policy drafts). No, for making or scoring hiring decisions on its own. A person should review every output and make every decision about a candidate, and some places require bias audits and notices before you use automated tools in hiring.

General educational information, not legal advice. Laws change; check the rules where you hire and talk to employment counsel.

What AI does well in HR

Task	Good fit?	Why
Job descriptions and job posts	Yes	Fast first drafts; you check for biased wording
Structured interview guides and scorecards	Yes	Same questions for every candidate supports fairness
Onboarding plans and checklists	Yes	Low risk, big time saver
Policy and handbook drafts	Yes, with review	AI drafts; HR and counsel verify against the law
Answers to routine employee questions	Yes, with review	Draft from your own policy text only
Ranking or rejecting candidates	No	High legal risk; keep a human decision-maker
Pasting employee medical, pay or ID data into public chatbots	No	Privacy and confidentiality risk

Which rules apply to AI in hiring?

New York City (Local Law 144): an automated employment decision tool needs an independent bias audit within one year before use, a public summary of the audit results, and notice to candidates or employees at least 10 business days before use. Enforcement began July 5, 2023.
Illinois: the Artificial Intelligence Video Interview Act (in effect since January 1, 2020) requires notice, an explanation and consent before AI analyzes applicants' video interviews. Since January 1, 2026, the Illinois Human Rights Act (as amended by HB 3773) makes it a civil rights violation to use AI that has the effect of discriminating against protected classes in employment decisions, or to use zip codes as a proxy for them, and requires employers to give notice when they use AI for those decisions.
Colorado: the original Colorado AI Act (SB 24-205) never took effect. In May 2026 it was repealed and replaced by SB 26-189, a narrower law on automated decision-making technology used in consequential decisions such as employment. It takes effect January 1, 2027, sets duties for developers and the businesses that use these tools, and gives people the right to correct inaccurate personal data. The Colorado Attorney General is finalizing rules.
California: Civil Rights Council regulations in effect since October 1, 2025 make clear that using an automated-decision system can violate state anti-discrimination law if it harms applicants or employees based on protected characteristics, and require employers to keep employment records, including automated-decision data, for at least four years.
Texas: the Texas Responsible Artificial Intelligence Governance Act (HB 149), in effect since January 1, 2026, bars developing or deploying an AI system with the intent to unlawfully discriminate against a protected class; disparate impact alone isn't enough to show intent. Federal and other state anti-discrimination laws still apply.
EU AI Act: AI used for recruitment and worker management is classed as high-risk. Under the EU's May 2026 agreement on simplifying the Act, the high-risk rules for employment systems are set to apply from December 2, 2027.
Everywhere in the U.S.: existing anti-discrimination law still applies. If a tool screens people out unfairly, the employer owns the result.

The four-fifths rule in plain English

This rule of thumb comes from the federal Uniform Guidelines on Employee Selection Procedures. Compare selection rates between groups. If one group's rate is less than 80% (four-fifths) of the highest group's rate, that is generally treated as evidence of adverse impact. Example: 50% of group A pass a screen and 30% of group B pass. 30 ÷ 50 = 60%, under 80%, so look closer before using that screen.

A safe 30-day rollout

Week 1: write a one-page team AI-use policy: approved tools, what never to paste in, who reviews outputs.
Week 2: start with job posts and interview guides only.
Week 3: add onboarding and policy drafts, with a named reviewer for each.
Week 4: measure hours saved and errors caught; keep, change or stop each use.

Three prompts to start

"Rewrite this job post in plain language, remove gendered or age-coded words, and list must-have versus nice-to-have skills: [paste]."
"Create a structured interview guide for [role] with 6 behavioral questions and a 1-5 scoring rubric for each."
"Turn this onboarding checklist into a 30-60-90 day plan for a new [role]: [paste]."
