What Should You Never Share With AI Tools?
Artificial intelligence tools like ChatGPT, Gemini, Claude, and others have quickly become part of everyday life.
People use AI to write emails, plan vacations, summarize documents, brainstorm ideas, and answer questions.
These tools can be incredibly helpful.
AI has quickly become part of many daily routines. I have used AI tools to help plan vacations, draft emails, and learn new things. Other people use AI for marathon training plans, meal planning, weekly menus, budgeting, and homework help.
In many ways, AI has become like having a digital assistant available whenever you need one.
However, many people are treating AI like a private conversation when they should be thinking carefully about what information they share.
The more comfortable we become using AI, the easier it is to forget that we are still sharing information with a technology platform.
I often hear people say they get better results when they have natural conversations with AI tools instead of asking a single question. While that may be true, it is important to remember that not every piece of personal information belongs in those conversations.
So what should you never share with AI tools?
Let's break it down.
Why This Matters
AI tools work by processing the information you provide.
Depending on the platform, your settings, and how the service operates, information you enter may be stored, reviewed, or used to improve services.
While major AI providers continue improving privacy controls, it is still important to think before you type.
A good rule of thumb is simple:
Never enter information that could harm you, your family, your finances, or your employer if it were exposed.
1. Social Security Numbers
Your Social Security number is one of the most valuable pieces of information a criminal can obtain.
Never enter:
Your Social Security number
Your spouse's Social Security number
Your children's Social Security numbers
If you need help understanding a document that contains a Social Security number, remove the number before sharing any information.
2. Banking Information
Avoid sharing:
Bank account numbers
Routing numbers
Debit card numbers
Credit card numbers
Even if you trust the platform, there is usually no reason for an AI tool to have access to this information.
3. Passwords
This may seem obvious, but people accidentally do it more often than you might think.
Never share:
Passwords
Passphrases
Security question answers
MFA recovery codes
If you need help creating a stronger password, ask the AI for examples instead of providing your actual password.
4. Tax Documents
Tax forms often contain:
Social Security numbers
Income information
Employer details
Banking information
Before asking questions about tax documents, remove sensitive information whenever possible.
5. Medical Information
While many people use AI tools to learn about health topics, be careful about sharing:
Medical records
Test results
Insurance information
Prescription details
If you choose to discuss health-related topics, consider removing personal identifiers first.
6. Confidential Work Information
This is one of the biggest risks today.
Never enter:
Company secrets
Customer information
Internal financial data
Legal documents
Security information
Sensitive business plans
Non-public company information
Many organizations now have specific policies regarding how employees can use AI tools.
If you use AI for work, make sure you understand your company's guidelines.
7. Personal Information About Other People
Think twice before sharing information about:
Family members
Friends
Coworkers
Customers
Clients
Their information deserves protection too.
8. Copies of Important Identification
Avoid uploading:
Driver's licenses
Passports
Birth certificates
Social Security cards
These documents contain valuable information that could be abused if exposed.
What Is Safe To Share?
AI tools are often best used for:
Brainstorming ideas
Learning new topics
Drafting emails
Creating checklists
Planning projects
General research
Vacation Planning
Meal Planning
Fitness training schedules
The safest approach is to share only the information necessary to accomplish your goal.
For example, instead of uploading an entire document that contains personal information, consider removing names, account numbers, and other sensitive details before asking your question.
Five Quick AI Safety Tips
1. Read Privacy Settings
Understand how your chosen AI platform handles information.
2. Remove Personal Details
Whenever possible, remove names, account numbers, and identifying information.
3. Follow Company Policies
If you use AI for work, follow your organization's rules.
4. Use Strong Account Security
Enable multi-factor authentication on AI accounts whenever available.
5. Think Before You Type
Ask yourself:
Would I be comfortable if this information appeared in public?
If the answer is no, don't enter it.
This includes information about your children, family members, finances, health records, or workplace projects.
The Bottom Line
AI tools are becoming part of everyday life.
They can save time, improve productivity, and help us learn new things.
But they are not a place to store your most sensitive information.
The safest approach is simple:
Use AI for ideas, learning, planning, and productivity—not for storing sensitive personal, financial, medical, or confidential information.
A few extra seconds of caution today can help prevent a much bigger problem tomorrow.
