Many people have started seeking advice from neural networks. But there is information that is better not to bring into the public domain.
The popularity of neural networks has skyrocketed over the past couple of years. With the help of artificial intelligence, people generate texts and avatars for profiles (why rent a studio and hire photographers when you have AI), structure work data, and even seek psychological help for personal issues. But are you sure this is safe?
All the data you provide to the neural network does not just disappear. It remains in the system and can be retrieved, for example, at the request of law enforcement agencies or in the event of a data breach. Therefore, trusting ChatGPT with something personal is like leaving a personal diary in the central square of a city. Even with protective measures in place, information can eventually fall into the wrong hands, including those of malicious actors. And the consequences of this are only becoming more serious in 2026.
There are things that should be permanently excluded from your dialogues with chatbots. More on this in our article.
Personal Data
Full name, home address, passport or driver's license number, date of birth — all of this is strictly taboo for disclosure in ChatGPT. It may seem convenient to ask the bot to format this information into a ready-made resume or application template. But the outcome could be disastrous.
In the event of a system hack or database leak, your personal data could be publicly accessible. This would be immediately exploited by fraudsters for identity theft, obtaining loans, or targeted phishing campaigns. Remember: you cannot control where and how this information will go after sending it.
Confidential Financial Information
AI can provide general advice on budget management or explain complex terms related to financial literacy. However, specifics should remain with you. Never enter bank card numbers, PIN codes, account details, passwords for banking apps, investment information, or tax returns. Even if you think the conversation is private.
This data is a goldmine for cybercriminals. Once in the system, it can be intercepted and used for direct theft of money. Additionally, sophisticated phishing schemes targeting you could be created based on this information. A financial consultant from ChatGPT is clearly a bad advisor.
Medical Details
The trend is alarming: more and more people are using chatbots for initial diagnosis. They describe symptoms, ask about medications, and share medical histories. This is very risky. First, AI is not a doctor. Its responses may be inaccurate, outdated, or simply dangerous, leading only to a deterioration in well-being. Remember that only a doctor can make diagnoses.
Secondly, the data itself — diagnoses, prescriptions, test results — is extremely confidential. Its leakage will not lead to anything good either.
Trade and Commercial Secrets
It may seem that ChatGPT can help with work-related issues. People often ask the neural network to edit internal reports, draft business proposals, or generate ideas for new products. However, any documents, strategies, unpublished data, correspondence with clients, patents, or developments are the property of the company.
By uploading them to public access, you are effectively taking secrets outside your organization. This data could be inadvertently used by the model to respond to other users. Such actions could lead not only to termination but also to serious lawsuits from employers or partners.
Requests Related to Illegal Activities
This point seems obvious, but the temptation is great. You should not ask AI how to create malicious software, manipulate people, or commit any other offense. Platforms strictly monitor such requests.
First, your account will be instantly blocked. Secondly, as experts, including leaders of major AI companies, note, developers are required to cooperate with law enforcement. By court order, all your correspondence may be provided to the relevant authorities for investigation. Conversations with the bot are not protected by attorney-client privilege.
The main principle of communication with any public AI in 2026 is caution. Imagine that every message you send could be read by strangers. If the information is too personal, financially significant, medical, confidential, or simply questionable — do not write about it. Use AI as a powerful but impersonal tool for working with public data and general knowledge.
