There is a small hesitation most people feel right before pasting a contract or a client’s details into a chatbot. That hesitation is correct. This free checker turns it into a quick, concrete answer: how risky this is, and what to strip out first.
Two things are easy to forget in the moment. Many free AI tools may use what you paste to train their models, and once text leaves your device you cannot pull it back. Neither is a reason to panic, but both are reasons to think for ten seconds before you hit paste.
You never upload anything here. You describe what you want to paste, and the checker gives you a plain risk level, a list of what to remove, and a sanitized prompt template. It all runs in your browser, and nothing you enter is stored.
Where the line actually is
Most of what people put into AI is perfectly fine. The goal is not to be paranoid, it is to know which side of the line something sits on before you share it.
Usually fine
General questions, public information, your own rough notes, and text with no names or private details.
Think twice
Resumes, contracts, and work documents. Often usable once you remove names, numbers, and contact details.
Keep out
Passwords and keys, government IDs, other people’s personal data, and confidential company material.
How the checker sizes up your risk
It looks at the most sensitive thing in what you are pasting, how you would classify the material, and the kind of AI service you are using, because a private on-device model and a public free chatbot are not the same bet. From there it gives you a risk level and, more usefully, the specific fixes: what to redact, a safer way to do the task, and a sanitized prompt template you can keep and reuse.
An educated estimate, not legal advice. The checker cannot see your document; it reasons only from what you tell it, and it does not guarantee confidentiality. For regulated data, your organisation’s policy and the law come first.
Who this is for
- Anyone about to paste a resume, contract, or report into an AI tool.
- Employees who handle customer or company data and want a quick gut check.
- Freelancers and small businesses working without a formal data policy.
- Privacy-minded people who would rather look before they leap.
Pasting more safely, in practice
- When you are unsure how sensitive something is, treat it as one level more sensitive. That instinct is almost always right.
- Share only the part you actually need help with, not the whole file.
- Swap real names and numbers for placeholders like [PERSON A], then put the real ones back yourself afterwards.
- For work material, use an employer-approved account rather than a personal one, and turn off training or history where the tool lets you.
Frequently asked questions
Is it safe to paste my resume or document into ChatGPT?
It depends on what is in it and which tool you use, which is exactly what this checker helps you weigh. Public free tools may use your input to improve their models, so redact personal details and check the tool’s data settings first.
Does this tool see or store my document?
No. It never sees your file. It reasons only from the options you choose, and everything runs in your browser, so nothing is uploaded, stored, or logged.
What should I never paste into a public AI tool?
Passwords and keys, government IDs, other people’s personal data, and confidential company material. Remove or replace these first, or use a private, approved tool instead.
Is this legal advice?
No. It is an educational risk estimate, not legal advice and not a guarantee of confidentiality. For regulated data, follow your organisation’s policy and any laws that apply.
How can I use AI with sensitive information more safely?
Share only the part you need help with, replace real identifiers with placeholders, turn off chat history or training where the tool allows it, and prefer a local or employer-approved tool for anything truly sensitive.
