Eight Things You Should Never Share With an AI Chatbot

Let's cut to the chase: those incredibly helpful AI chatbots you use daily? Your conversations with them aren't private. Not even a little bit. Everything you type into ChatGPT, Gemini, Claude, and their peers could be read, analyzed, and used in ways you probably haven't considered.

Here's the harsh truth: a Stanford study found that most major AI companies use your chat data by default for training purposes. Some keep it indefinitely, merging it with other personal data they collect about you. While you might be able to opt out of training, your chats can still be read by human reviewers. And let's not forget the ever-present risk of data breaches.

Think of it this way: if you wouldn't shout it on a busy street corner or hand it to a stranger, you shouldn't be typing it into an AI chatbot. To keep your digital life secure, here are eight things you should absolutely never share:

• Login Credentials: This should be obvious, but don't ever paste usernames, passwords, or documents containing them into a chatbot. Ever. AI is also terrible at generating secure passwords – stick to your password manager or embrace passkeys.
• Financial Data: Your chatbot isn't a financial advisor. Bank statements, credit card numbers, investment portfolios, account balances – keep them to yourself. Sharing this sensitive data anywhere that isn't explicitly secure is an open invitation for fraud and theft.
• Medical Records: AI chatbots are not doctors. Uploading your medical history exposes sensitive health information to potential breaches and provides data points for LLM training you likely don't want. Keep your health records private.
• Personally Identifiable Information (PII): Your name, address, email, phone number, birth date, Social Security number, passport info – basically anything that screams "you." Don't share it. This is prime real estate for identity theft.
• General Health Information: Even seemingly innocent health queries can be risky. Asking for "heart-friendly dinner recipes" could subtly allow an AI to infer health status, potentially becoming accessible to insurers. This extends to topics like sexual health, medication, or gender-affirming care.
• Mental Health Concerns: Your chatbot isn't a therapist. While AI models are evolving, they've been unhelpful at best and actively harmful at worst when it comes to mental health. For genuine support, seek out real human professionals.
• Photos: AI image editing is cool, but uploading personal photos isn't without risk. Your images could be used for training, and their metadata often contains your GPS location. At a minimum, strip EXIF data before sharing, and never upload images of minors.
• Company Documents: Using AI for work tasks is tempting, but beware of sensitive company information. Uploading confidential files to a public chatbot could violate company policy and expose proprietary data. Assume your employer is watching (or at least, has a policy against it).

The bottom line? Be incredibly cautious. Assume everything you feed into an AI chatbot is stored indefinitely and could be read by human eyes or used to train the next iteration. Prioritize your privacy settings, opt out of data sharing where possible, and always err on the side of caution. Your digital security depends on it.
