Free AI chatbots are genuinely useful, and staff reach for them to rewrite emails, summarise notes, or draft documents. The risk is what goes into them. On many free tools, what you type can be stored, reviewed, or used to train future models, which means pasting in a client list or a contract can quietly hand it out of your control. Using these tools well is about what you share, not avoiding them entirely.
Treat the chat box like a public postcard
Assume anything you paste into a free consumer AI tool could be read by others or retained. If you would not write it on a postcard, do not paste it into a public chatbot without thinking first.
What should never go in
Keep out customer personal data, staff records, card or bank details, passwords, unpublished contracts, and anything covered by confidentiality or data protection duties. Under UK GDPR, personal data pasted into the wrong tool can be a reportable breach.
Anonymise before you ask
You can often get the help you want by removing the identifying details first. Replace real names, account numbers, and specifics with placeholders, so the tool sees the shape of the problem but none of the sensitive content.
Check the settings and the tier
Many tools let you turn off training on your chats, and business or enterprise versions often promise not to use your data at all. If you rely on AI for real work, a paid business tier with proper data handling is worth it over a free consumer account.
Agree a simple staff rule
A short, clear policy helps everyone: which tools are allowed, and what must never be pasted in. Most accidental leaks come from a helpful member of staff who simply did not realise the data would leave the building.
Red flags to watch for
- Pasting real customer names, contact details, or records into a free chatbot.
- Uploading a whole spreadsheet, contract, or database export to summarise it.
- Sharing passwords, card numbers, or internal financial figures for convenience.
- Using a personal free AI account for confidential work tasks.
- Assuming the tool forgets everything, without checking its data settings.
- No agreement among staff about what is and is not allowed in AI tools.
