A manager pastes a draft contract into a free AI tool to tighten the wording before a meeting. It works well, and nobody thinks twice. Nobody at the company knows it happened, and the contract text now sits somewhere the company doesn’t control.
That small moment is what people mean by shadow AI. It’s happening in most organizations, and it’s usually well-intentioned. The goal isn’t to catch anyone. It’s to see what’s in use, set clear rules, and give people better options. Here’s what shadow AI is, why it happens, and how to get it under control.
What is shadow AI?
Shadow AI is the use of AI tools, features, or agents that an organization hasn’t approved, can’t see, or can’t govern. It covers everything from a personal chatbot account used for work to an automation someone built on their own that touches company data.
Most of it isn’t malicious. People use these tools to move faster, and many don’t realize that a quick prompt can send sensitive information outside the organization. That’s why shadow AI is better understood as a visibility problem than a discipline problem.
What are common examples of shadow AI?
The most common example is a free or personal chatbot account used for work tasks like drafting, summarizing, or analyzing. AI note-takers that join meetings and keep transcripts are another. Browser extensions that read and rewrite what’s on screen count too, as do AI features that a team switches on inside an already approved tool without a review.
Other examples include AI tools connected to work email, files, or calendars, and homemade agents or automations that act on company data.
Notice that few of these involve installing anything. A browser tab or a settings toggle is enough, which is part of why shadow AI is so easy to miss.
Why do employees use shadow AI?
Speed is the main reason. People have deadlines, AI helps them meet those deadlines, and the approved route is slower or doesn’t exist. In other cases the approved tools are hard to use, or they lack the AI features people have already seen elsewhere. Rules may be unclear or missing, so people make their own call.
It isn’t limited to junior staff, either. Senior leaders use unapproved tools too, often because they’re busy and confident. When a rule is only applied to some people, it stops feeling like a rule.
It helps to treat shadow AI as a signal. When many people reach for the same unapproved tool, that tells you what your approved options are missing.
What are the risks of shadow AI?
The biggest risk is sensitive data leaving the organization. When someone pastes customer details, financials, or contract language into a tool the organization doesn’t manage, it may not be able to control where that data goes or how it’s used. Terms differ between free and business versions of the same tool, and many people never read them.
The second risk is that there’s no record. Nobody can say what was shared, what the AI produced, or which decisions relied on it. That makes it hard to answer an auditor, a customer, or your own leadership. AI can also sound confident and be wrong, so outputs that go into contracts, reports, or customer messages without review can spread errors.
There are quieter risks as well. Client agreements and regulations may limit which tools can touch certain data. Subscriptions and licenses pile up with no one managing the cost. And when a tool or automation depends on one person’s account, it can break or turn into a liability when that person moves on.
How is shadow AI different from shadow IT?
Shadow IT is the use of unapproved software or services, such as a file-sharing account that nobody in IT set up. Shadow AI shares that root, but it differs in three ways.
First, it involves data and decisions, not just storage.
Second, it needs almost no setup, since a browser tab or a built-in feature is enough.
Third, it produces outputs that people act on, so a wrong answer can flow into real work.
Your existing shadow IT policies are a good starting point. Most of them were written before these tools were common, though, so they usually need updating. For the broader picture, see our post on enterprise AI governance.
Can you ban shadow AI?
You can ban it, but a ban on its own rarely works. The work still needs to get done, so many people keep using the tools, and the use moves out of sight where you can’t offer guidance or spot problems.
A better approach combines visibility, clear rules, and approved options that people want to use. That way, people can follow the rules without giving up speed.
How do you get shadow AI under control?
Start by seeing what’s in use. Ask people openly, look at app approvals and connected apps, and build a simple inventory of the AI tools, features, and agents across the organization. Make it safe to speak up, because people won’t share what they fear will get them in trouble.
Next, set clear rules. Keep them short, tie them to the kinds of data people handle, and give people an easy way to request a tool they need. Then offer approved tools that people actually want to use. If the safe option is slow or limited, the workaround wins. Our post on Copilot governance covers one way to roll out an approved tool with the right guardrails.
Finally, keep watching. Usage and permissions change over time, so regular reviews keep a good setup from slowly drifting back into the shadows.
Where should you start?
Start with visibility. You can’t govern what you can’t see, so the first step is a simple inventory of the AI in use, including the unofficial kind. Most organizations find more than they expected, and that’s a useful starting point, not a failure.

Frequently asked questions about shadow AI
What is shadow AI?
Shadow AI is the use of AI tools, features, or agents that an organization hasn’t approved, can’t see, or can’t govern. It ranges from a personal chatbot account used for work to a homemade automation that touches company data. Most of it is well-intentioned, but it can send sensitive information outside the organization without anyone noticing.
What is an example of shadow AI?
A common example is an employee pasting a draft contract or customer notes into a free AI chatbot to improve the wording. Others include AI note-takers that join meetings, browser extensions that rewrite on-screen text, and AI features a team switches on inside an approved tool without review. Homemade agents and automations also count.
Is shadow AI illegal?
Shadow AI isn’t illegal in itself, but it can create legal and compliance problems depending on the data involved, your client contracts, and the regulations you operate under. Using an unapproved tool with regulated or confidential data is the riskiest case. Legal counsel should weigh in on your specific obligations, and clear rules plus approved tools reduce the exposure.
Why is shadow AI risky?
The main risks are sensitive data leaving the organization, no record of what was shared or decided, and AI outputs used in real work without review. There are also compliance concerns, unmanaged costs, and continuity problems when tools depend on one person. Because shadow AI is hard to see, these risks tend to build up quietly.
What is the difference between shadow AI and shadow IT?
Shadow IT is the use of unapproved software or services. Shadow AI is similar, but it also involves data, outputs, and decisions, and it needs almost no setup. A browser tab or a built-in feature is enough. Because people act on what AI produces, a wrong answer can flow straight into real work.
Can you ban AI at work?
You can, but bans on their own rarely work. People still have work to do, so use often moves out of sight where it can’t be guided or monitored. A better approach combines visibility, clear rules, and approved tools people want to use.
How do you find shadow AI in your organization?
Start by asking people openly and making it safe to answer. Then review app approvals, connected apps, and the admin settings of the platforms you use, and build a simple AI inventory. Repeat the review regularly, since new tools and features appear all the time.
