Private Detectives and Investigators

Many detective tasks involve gathering and sorting information, and computers already help with some of this. For example, U.S. data says investigators routinely “search computer databases, credit reports, public records…” ^[1] and then “gather, analyze, compile, and report” information ^[2]. Advanced software (some using AI) can speed up this research.

Law enforcement agencies now use AI like facial‐recognition and video‐analysis to spot suspects in crowds or track clues from surveillance footage ^{[3] [4]}. Private investigators have access to similar tools – for instance, many use legal/operator databases or even AI-powered search filters to find people or public records quickly. However, writing reports and summaries still relies on human skill.

Guides like O*NET list “write reports or case summaries to document investigations” as a core task ^[1]. We found no evidence that AI fully writes case reports; tools may help draft text, but final judgment and detailed writing remain in human hands.

Detective firms already use a lot of digital tools, but adopting new AI happens in steps. Basic search and data tools are common: O*NET notes investigators often use tools like LexisNexis or Google for research ^[1]. However, cutting-edge AI (like real-time face-matching or big-data crime analysis) can be expensive and complex.

Most private detectives work in small firms or as consultants, so they may not invest in costly AI systems at once. Their pay (around $60K per year on average ^[2]) is moderate, so expensive software must clearly pay off. Still, technology that cuts work time or finds clues faster can be appealing, so practical tools (like database search engines or analysis software) are gradually adopted.
