Here's what the law and typical employer policies say about using AI for personal projects during work hours. ## The short answer There is **no federal law that outright prohibits** using an employer's computer or internet for personal reasons during work hours. Whether you can do it — and what happens if you do — is governed almost entirely by **your employer's written policies** and, for hourly workers, by **wage-and-hour law (FLSA)**. The AI-specific wrinkle is that **who owns the output** can depend on which tools you use. ## 1. There's no law against it — but policies govern it - In the US, "there is no formal law prohibiting the use of an employer's PC for personal reasons during work hours." Instead, companies are expected to adopt **internet/computer usage policies** that define acceptable use, and violating those policies can lead to discipline. ([Employment Law Handbook](https://www.employmentlawhandbook.com/hr/what-the-law-says-about-personal-internet-usage-at-work/)) - Employers can legally **monitor** company-issued equipment under the Electronic Communications Privacy Act of 1986, since the equipment remains company property. Some states (e.g., Connecticut, Delaware, New York, California) impose notice/consent requirements for monitoring. ([Employment Law Handbook](https://www.employmentlawhandbook.com/hr/what-the-law-says-about-personal-internet-usage-at-work/)) - So the practical rule: **check your employee handbook / AI-use policy.** If it says company time and tools are for work only, using AI for personal projects violates that policy even though no law forbids it. ## 2. The AI-specific ownership question A key legal risk with AI side projects is **ownership of the output**: - If you use your **employer's enterprise AI tooling** (e.g., company ChatGPT/CoPilot accounts, company laptops, company data), the employer may claim rights to what you produce — and your employment contract's invention-assignment clause may sweep in AI-assisted work. - Using **personal AI accounts and personal devices** for a personal project is the cleaner path if you want to keep ownership, but you should still check your contract's IP/invention-assignment language.

Hourly vs. salaried — yes, it matters a lot This is the biggest legal distinction: **Hourly / non-exempt workers:** - Under the FLSA, non-exempt employees must be paid for **all hours worked**, including time they are "suffered or permitted" to work — even unauthorized work. ([U.S. Department of Labor — Off-the-Clock](https://www.dol.gov/agencies/whd/flsa/off-the-clock)) - If you're clocked in and doing a personal AI project, that time is generally **compensable** — the employer must pay you for it, and the employer is responsible for preventing "off-the-clock" work. ([MyHRConcierge — Compensable Time for Non-Exempt Employees](https://myhrconcierge.com/2025/08/07/employers-guide-to-understanding-compensable-time-for-non-exempt-employees-under-the-flsa/)) - Practical implication: doing personal AI work while clocked in is risky for **both** you and your employer — it can create wage-and-hour liability, and many employers prohibit it. **Salaried / exempt workers:** - Exempt employees are paid a salary regardless of hours, so the FLSA "hours worked" tracking doesn't apply the same way. The constraint here is **not wage law** but your **employer's policy** on using company time and tools for personal purposes. - Even for salaried workers, using company AI accounts/equipment for personal projects still raises the **ownership** and **policy-compliance** issues above. ## Bottom line - **Legally:** No law bans personal AI use during work hours, but your employer's policies do govern it, and employers can monitor your company devices. - **Hourly:** Doing personal AI work while clocked in is compensable time and can create wage-and-hour issues — generally discouraged/risky. - **Salaried:** The main concerns are policy compliance and IP ownership, not wage law. - **To protect yourself:** Use personal AI accounts and personal devices for personal projects, do them outside paid/working hours, and review your employment contract's invention-assignment and AI-use clauses. *Note: I'm not a lawyer, and this is general information, not legal advice.
