What you type into an AI tool doesn't always stay private. Some consumer AI accounts use your input to improve their models, which means sensitive information could resurface elsewhere. A few simple habits and the right account type keep your company data protected.
What happens to the text you type into an AI tool?
Text you type into an AI chat gets sent to a server for processing. Depending on your account type and settings, that text might get stored. In some cases, it feeds back into training the model over time.
This isn't automatically dangerous. But it means you should treat an AI chat window like any other online form. Don't assume anything typed into it stays private by default.
What's the difference between a business AI account and a consumer one?
Most AI providers offer both free consumer accounts and paid business accounts. The gap between them matters more than most people realize.
- Consumer accounts often use conversations to improve the model unless you change a setting
- Business accounts typically include stronger privacy terms and often exclude your data from model training
- Business accounts usually offer admin controls, so a company can manage who has access and what they can do
Anthropic offers a clear example of how this split works for one provider. Its updated consumer terms state that "we're now giving users the choice to allow their data to be used to improve Claude." These changes apply "to users on our Claude Free, Pro, and Max plans." They don't apply to Claude for Work, Claude for Government, Claude for Education, or API use. Anthropic's Commercial Terms of Service go a step further. They state that "Anthropic may not train models on Customer Content from Services."
Every provider writes its terms differently. Check each provider's terms before you sign your team up for a business plan, rather than assuming every business account excludes training.
If your team uses AI regularly for work, a business account is worth the extra cost for the added privacy protection.
What should you never paste into an AI tool?
Some categories of information should stay out of any AI tool, no matter the account type. Treat AI chat windows like a public forum.
- Customer names paired with private details, like health, financial, or account information
- Passwords, API keys, or anything used to log into a system
- Unreleased business plans, contracts, or legal documents
- Any data your company has a legal obligation to protect
The OWASP Gen AI Security Project lists what counts as sensitive here. It "includes personal identifiable information (PII), financial details, health records, confidential business data, security credentials, and legal documents." OWASP also recommends that AI applications offer "clear Terms of Use policies, allowing users to opt out of having their data included in the training model."
If a document contains this kind of information, don't paste it into an AI tool, even to summarize it.
Why do access controls matter for AI tools?
Access controls decide who on your team can use an AI tool and what they can do with it. Without them, anyone with a login could paste in sensitive files without anyone else knowing.
A real-world example shows what can go wrong. After sensitive internal data leaked to ChatGPT, Samsung temporarily restricted generative AI tools on company-owned devices. Samsung noted that it's difficult to "retrieve and delete" data stored on external servers. It added that information sent to such tools could be disclosed to other users.
Basic access controls include:
- Limiting AI tool access to employees who need it
- Turning off any setting that allows conversations to train the model
- Reviewing which third-party AI tools connect to your company accounts
- Removing access promptly when someone leaves the company
These steps overlap with the website security basics many small businesses already follow, and they cut a lot of avoidable risk.
What should a simple AI policy include?
You don't need a long legal document to keep your team safe. A short, clear policy is more likely to get followed.
A workable policy might state:
- Which AI tools are approved for work use
- What categories of information can never be pasted in
- Whether business or consumer accounts should be used
- Who to contact with questions about a specific use case
Keeping the policy short and specific makes it far more likely that people will follow it. If you want help setting up AI tools for your business the right way, our team offers AI systems support to build these guardrails from the start.
The short answer
AI tools are safe to use at work once your team understands what happens to the data they type in. Business accounts, clear rules about what never gets pasted in, and basic access controls cover most of the real risk.
Frequently asked questions
How long do consumer AI accounts keep your data? Retention periods vary by provider and by setting. Anthropic's updated consumer terms state, "we are also extending data retention to five years, if you allow us to use your data for model training." Check each provider's terms for its own retention rules.
Do business AI accounts always exclude your data from training? Don't assume they do. Anthropic's Commercial Terms of Service state that "Anthropic may not train models on Customer Content from Services," but this protection is specific to Anthropic's commercial plans. Check each provider's terms before you rely on the same protection elsewhere.
What kinds of information count as sensitive for AI tools? Sensitive information covers more than passwords and login details. The OWASP Gen AI Security Project defines it as including "personal identifiable information (PII), financial details, health records, confidential business data, security credentials, and legal documents."
