Learn how to use Private Investigator Software, Apps, and Online Services

Technology plays a key role in any investigation business. Detectives use a combination of private investigator software such as online search tools, OSINT resources, computer software, and mobile apps to support many aspects of investigations.

Private investigator software is a general term that encompasses programs and applications installed on a computer or web server and online, web-based solutions known as SAAS (Software as a Service). SAAS is a software licensing and delivery model that is offered on a subscription basis and is centrally hosted. Users access the service via a web browser on a PC, tablet, or mobile device. Also, it includes apps installed on tablets and mobile devices.

Private investigator software  can be used to:

  • Manage business operations such as accounting, billing, invoicing, and customer contact management
  • Manage cases, including assignments, case documents, photos, contacts, interview notes, expenses, and more.
  • Search for public and non-public records such as criminal histories, divorce records, address histories, driving records, financial records, and more.
  • Conduct online research and due diligence, download documents, compile dossiers and prepare reports for court cases
  • Coordinate communications with clients, vendors, witnesses, business partners, and other investigators. This includes communication via phone, text, video messaging, walkie-talkie, chat, and more.

Following is an overview of the various types of software used by private investigators. We tried to list only the best in each category. If you’re looking for general software, check out the list of best-selling software on Amazon. Please leave a comment if you have suggestions.

Case Management Software and Online Services

Case Management Software programs help PIs manage information related to investigating cases. For example, to enter and store client records, collect billing information, employee and payroll records, billing, contacts, and more.

The latest case management solutions come in the form of cloud-based services. This allows easy access via computer, tablet, and mobile devices from anywhere in the world. Case management software is particularly useful for larger private investigation agencies and law offices. Below are links to our reviews of several of the best industry-leading systems:

Online Background Checks and Public Records Search Databases

There are several reputable companies with the ability to run background checks online. These online services aggregate billions of public records from various disparate sources. Then, they offer easy online access to allow people to conduct background checks, verify facts and employment history, and find missing people. And, best of all, they are surprisingly affordable.

For example, BeenVerified Background Search offers plans that start at just over $20 per month. They provide search capabilities for public records, address and phone number searches, email searches, and more. In addition, they provide mobile access via iPhones, iPad, and Android devices.

Following are reviews of some of the best mobile apps that are useful for detectives:

Computer Monitoring and Keylogger Tools

Various computer monitoring software programs are available to assist in conducting investigations, computer forensics, and online surveillance.

Investigators who conduct computer crime or security investigations should be familiar with general computer programs for business communications, customer relationship management (CRM), accounting, data recovery, and security. 

The following are private investigator software programs used to monitor PC activity, monitor network activity, and more. Please, note that most of the solutions in the articles below aren’t as powerful as the latest Mobile Phone Spy Software:

  • Email Monitoring – Monitor locally, and in some cases remotely, the activity of computers. It also discusses Email Spying and other forensic tools.
  • Keyloggers – Keylogger tools are programs that log computer keystrokes and record user activity on a computer. For example, parents can use it to keep track of incoming and outgoing messages.
  • Network File Monitoring – Designed to monitor and track user activity on a computer network.
  • Real Time Spy – RealTime Spy is a computer monitoring program that allows you to monitor the activity on a personal computer.
  • Spy Anywhere System – Another computer monitoring tool.

General Computing

Private investigators deal with the same challenges as any business owner. Therefore, they must have a solid working knowledge of typical business operating programs. Examples include various Operating Systems, such as Windows, Linux, Mac, etc.

In addition, detectives need to know about productivity software such as Microsoft Office, Google Docs, etc. Other business solutions include:

  • How to Setup a Website – This article advises establishing an online presence for your investigative business. You’ll find helpful tips on web design software. In addition, we offer suggestions for content management tools. And finally, we suggest some web hosting options.

Online Search Tools and Software to Avoid

Various online search programs are available to help look up information online. The most common private investigator systems search for people, look up addresses and phone numbers and conduct background investigations.

Beware of such programs as Net Detective and Urgent Detective that claim to offer free background check capabilities. They are of little value to the serious professional.

  • Net Detective Online – This online detective program claims to help you find everything from criminal records, divorce records, and driving records. However, it is little more than an outdated address search or white pages search tool
  • eDetective – Yet, another online search tool that claims to provide free background check capabilities. However, it is simply a scam. We do not recommend its use.
  • Urgent Detective – Another online search tool that claims to provide free background check capabilities.

We tested these services and did not feel they lived up to the claim of offering free background check capabilities. You are unlikely to find a legitimate service that provides a truly free background check. Most of these are free (and weak) public records searches.


You don’t necessarily need to be a private eye to use many of these programs and apps. Nor do you need to be licensed. However, some companies may require certain types of various certifications to confirm that you are operating a valid business and have a need to access information for legitimate business reasons.

  5. Do you guys provide soft ware for MPI (military police investigator)? We are looking for a soft wear that could help us out. Could you please let me know what you provide and the cost of the software? Thank you.

  6. I need to pull up a fishing license for three individuals in Alaska; however, the Alaska Fish and Game requires a notarized signed letter from each individual I am looking into. This kind of defeats the purpose of looking into these individuals. How do you circumvent this and obtain the licenses without their knowledge?

    Thank you.

    • Sounds like a tough one. Many states allow verification of professional licenses online, but I don’t think fishing licenses are considered professional licenses.

      Earlier this year, Alaska enacted legislation that allows fishermen to carry electronic licenses on their smartphone. This is intended to make it easier for law enforcement to verify that they have a valid license.

      These are just ideas, but since law enforcement can check, perhaps you might try to contact law enforcement in the appropriate city or town for assistance.

      Another option might be: Contact the Alaska Professional Licensing division’s Investigative Unit at They might be able to point you in the right direction.

  7. I need a private investigator to investigate to investigation online for me I have really weird things in my phone and I think it’s my boyfriend I don’t want to believe it could you please call me my name is Rachel Allen my phone number is 573-721-2546 thank you.

    • Also, review all of the applications installed on your phone. Disable or uninstall any apps that don’t look familiar to you. Be careful not to disable any important apps that are necessary for your phone to run. Once you disable any suspicious apps, see if the weird things continue to happen.
