We Got Chatbots to Turn Over Personal Information. How to Keep Yours Safe


Generative artificial intelligence models are trained on vast troves of information gathered from the internet. And your phone number is probably in there.

While some AI chatbots are trained to refuse to provide personal information about private individuals, it’s startling how easy it is to get them to do so anyway. With growing awareness about how these services can fork over phone numbers and addresses, we decided to see what the most popular products would do. Yes, a few of us at CNET tried to see how easy it is to dox ourselves.

If you’re on the internet, you’ve probably heard of doxxing (the release of people’s personal information). So it may be alarming that reports recently surfaced regarding AI chatbots revealing private individuals’ phone numbers

This isn’t the only privacy concern regarding artificial intelligence. A 2025 study from Cornell University discovered that at least five leading AI companies — Anthropic, Google, Meta, Microsoft and OpenAI — automatically use users’ inputs to train their chatbots unless the user opts out. Of those, Meta and OpenAI retain user data indefinitely. That means these AI models are trained not just on the old phone book (remember those?) that has your childhood home listed in it. It could contain the information you gave a chatbot a couple of years ago, however private that was.

But how much can chatbots reveal? And is there anything you can do to stop it?

Do chatbots give out people’s personal information?

Based on our recent experience, it depends. A couple of us at CNET tried out a handful of chatbots to see what information we could pull about ourselves and relatives. While I won’t share any screenshots or too many details regarding our queries, because, well, we don’t want to dox ourselves, I can tell you this: Grok seemed to be the most “willing” chatbot when it came to getting answers, but some staffers were able to pull some information from ChatGPT, too.

For example, after some questioning, my colleague Jon Reed was able to get ChatGPT to provide plenty of possible addresses for people in his area with the same name, but not his address. However, the chatbot did eventually reveal a relative’s address. ChatGPT provided Reed with phone numbers, including an old landline phone number he once used, and it easily provided a relative’s cellphone number.

I was unable to get the chatbot to provide any address information, and when I asked further, it responded: “Even if an address appeared on a people-search site, I wouldn’t help share or verify a private person’s home address.” 

It also stated, “I can’t help find or share a private person’s phone number.” 

An OpenAI representative didn’t immediately respond to a request for comment on how ChatGPT is intended to handle personal information.

(Disclosure: Ziff Davis, CNET’s parent company, filed a lawsuit against OpenAI in 2025, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Grok, however, was the worst offender in our test. When CNET staff tried Grok, putting in a name and asking for an address, it pulled multiple present and past addresses within seconds. At the end of the query, the chatbot stated in part:
“Note: These come from publicly available records and directories. Home addresses are private; I recommend contacting him through professional channels.” 

Later, the chatbot also provided a former phone number with the following note: “I don’t recommend sharing or using personal phone numbers found in public records.”

An xAI representative didn’t immediately respond to a request for comment regarding its privacy practices.  

Gemini, on the other hand, provided public-facing social media profiles, but would not give any personal information and added this note at the end of the query:

“A note on privacy: To protect personal security, personal mobile numbers for individuals who are not public officials or designated business contacts are typically not released by AI services. Professional platforms like LinkedIn or business-specific email addresses remain the most reliable and respectful way to get in touch.”

Claude also refused to provide personal information. 

How does our personal information end up on the internet to begin with?

This year, I bought my first home and was swiftly inundated with scam mail delivered directly to my door. Months later, it’s still trickling in. The scariest part was that the mail looked completely legitimate. It turns out that when you buy a home, your address and other information related to the home-buying process become a public record, at least in many places. 

Additionally, when you register to vote, violate the law or even shop online, your information can become easily accessible in certain places. 

A sneakier example is when you download a new app on your phone and click “accept terms” without reading all of the legal jargon and fine print. At that moment, you’re often agreeing to your data being shared with third parties. This is one way your phone number and email end up on mailing and call lists, and how more of your personal information can end up on the internet.

As a first step, you can remove your address from the internet so that, regardless of whether people use search engines or chatbots, your personal information stays private. 

“Chatbots will only tell people what info they can find, which means you can protect your privacy by checking what personal information is online and removing it where you can, like from Whitepages,” CNET security expert Tyler Lacoma says. “When in doubt, I suggest spending some time with ChatGPT, Gemini and other chatbots to see what they say about you.”

Ultimately, if you don’t want a chatbot to reveal your private information, you must ensure it’s no longer readily available online. 

What about data removal services?

Data removal services are designed to remove your personal information from public databases and public records. Companies such as DeleteMe aim to reduce your data online, which can reduce the number of spam calls and marketing communications you receive. Many of these types of services are currently being tested by CNET to determine the best options.

If Game Two of their first-round playoff series with the Denver Nuggets saved the 2025-26 season for the Minnesota Timberwolves, Game Three showed why it should be saved. 

The Timberwolves were a different beast while decisively thumping the Nuggets, 113-96 Thursday night at Target Center, in a game that wasn’t nearly that close. These Wolves were the mythical creature we’d heard about in preseason lore, purposefully locked and loaded to be both marauding and staunch. They owned both ends of the court, gleefully transferring back and forth from irresistible force to immovable object. 

A quartet of Timberwolves deserve special mention, but it begins with Jaden McDaniels. After his team had toppled Denver to even the series at a game apiece Monday night, McDaniels used the sizable chip on his shoulder to etch some graffiti into the public discourse, casually castigating the most prominent Nuggets players by name as “bad defenders” in a matter-of-fact manner that had the media compelling him to confirm what he had just said. 

Trash talk is fleetingly fungible in the jaundiced social environment of 2026, functioning more like coupons than currency in that it needs to be rapidly leveraged before its expiration date. The common perception naturally was that McDaniels was calling out the Nuggets. But in a more subtle, profound way, he was also putting his teammates on notice. 

All season long the Timberwolves have procrastinated on their full potential, frequently demonstrating that their preseason talk about maturity and commitment was cheap. By contrast, those words uttered by McDaniels were expensive. He had just picked a fight with the opponent, leaving open the question of how many of his teammates would join him in the fray. 

That he would lead the charge was established early, after the Timberwolves’ top two scorers, Anthony Edwards and Julius Randle, had each missed a pair of open looks against Denver’s bad defenders in the game’s first 90 seconds.  

With the game still scoreless, the NBA’s best pick-and-roll combo, Nikola Jokic and Jamal Murray, were clustered around the foul line with Minnesota’s best defenders, McDaniels and Rudy Gobert. As they jammed up Jokic, McDaniels picked the ball loose and started sprint-dribbling the other way. To no one’s surprise, Donte “Ragu” DiVincenzo was also on his horse in transition, receiving a pass from McDaniels and then lobbing it back for a Jaden slam against a hapless Murray and Murray’s late-arriving teammate, Cam Johnson, who committed the foul that allowed McDaniels to finish with the “and-1” free throw. 

On the Timberwolves next offensive possession, McDaniels muscled his way to two offensive rebounds, feeding Ragu off the first one for a missed three-pointer, which he corralled for the second one and executed the putback in traffic. It was McDaniels 5, Nuggets 0, setting the tone for a game in which not only did the Wolves never trail, but never let the lead go under double digits after McDaniels made a consecutive pair of driving layups eight minutes into the game. 

“Spectacular. I thought his activity offensively in the first quarter was outstanding,” said Wolves coach Chris Finch after the game. “He was inspirational.” 

Among the most inspired were McDaniels fellow wing players, Ragu and Ayo Dosunmu. Ragu is exactly the kind of player who will have your back in a squabble, and his galvanized performance seemed borne of satisfaction that someone else had clarified the mission. As usual, the Timberwolves were at their best with him on the court: +20 in the 32:54 he played, -3 in the 15:06 he sat. 

“He makes so many hustle plays, momentum plays, different styles of plays.” Finch raved. “He’ll make a shot, get a transition bucket, he’ll rebound, get a steal, blow something up. So many different plays. He’s just a basketball player.”

Then there was Ayo, whose fearless, blazing, bee-lines for the bucket were quicksilver kryptonite for a Nuggets defense that is neither swift nor rugged. “I’ve been waiting for him to wake up a little bit in this series,” Finch accurately observed. “The downhill mindset that he played with all season for us was back.”

Back with the sort of multipurpose propulsion that leaves witnesses with giddy whiplash. Ayo led the team with 25 points and 9 assists in 32 minutes of time-lapse hoops, the lone blemish being three clanks from long range. Why chuck treys when you can so easily undress players in the paint? Ayo was 10-for-12 on two-pointers and none of those dozen shots came from anywhere but beneath the rim. Five of his nine dimes likewise yielded layups or dunks, which means he personally accounted for 30 of the 68 points in the paint by the Timberwolves on Thursday, doubling up the Nuggets’ 34.

Which brings us to the non-wing in Game 3’s ring of honor, Rudy Gobert. For the third straight game, Gobert blunted the supposed advantage Denver had with the magical playmaker Nikola Jokic at the controls. Suffice to say that in the last five quarters, Jokic has shot 8-for-33 from the floor. If that continues, the Nuggets are toast in this series. 

When I asked Finch after the game if the herculean job Gobert was doing on Jokic made planning his defense simpler and better thus far, he replied, “Rudy is making all of us look good right now with his defense.” 

Amen.

If there is an asterisk on this game, it would be the absence of Denver’s brutishly versatile power forward Aaron Gordon. Nuggets coach David Adelman should be given a lot of credit for his honesty and transparency in dealing with the media during his first full season at the helm, but it came back to bite him and his team during the pregame presser, when he was clearly rattled and dejected by the sudden unavailability of Gordon, whose playing status went to “probable” to “out” in a period of a few hours due to a chronic calf strain. 

Gordon is far and away his team’s best defender, making the timing of his injury especially troublesome in the wake of McDaniels laying down his marker. Rattled is a good way to describe the entire team’s performance in the first quarter, an emotional wounding that needs to heal as fast as Gordon’s body if the Nuggets are going to be competitive in a series that had dramatically been flipped on its head over the past three days. 

That the Timberwolves played with such dominance despite mediocre outings from Ant and Randle would be a good thing for both of those current cornerstones to keep in mind. Ant was beset by foul trouble and Randle had a solid second quarter, but it stood out that neither player fully embraced what so often works on offense when the Wolves are at their best: Push the pace, move the ball, move without the ball, and make quick decisions. Ant and Randle can still be first among equals and blend into that catechism if they stay attuned to the possibilities of a greater good, one that all of sudden doesn’t have to end with them being postseason fodder for the Spurs or the Thunder. 

Not when you’ve got three wings at a collective peak, with a chaser of Rudy semi-clowning the Joker.
