Say how you used AI, clearly and briefly
Most people who use AI on their work would rather not have to explain it, and a vague “I used AI” invites the worst guess. Tick what you used it for and what you did yourself, and get a short, specific statement for your teacher, client, manager or publisher. Nothing you enter leaves this browser.

New to this? What it does, in plain words
It turns a few ticks into a short, honest note that says what AI did on a piece of work and what you did.
Use it when a course, a client, an employer or a publisher asks you to declare AI use, or when you would rather say it first. A student can state that AI gave feedback on a draft and wrote none of it. A freelancer can tell a client which parts were drafted with AI and checked by hand. A specific statement reads very differently from a vague one.

How to use it
- Pick who will read it. The wording changes to suit them.
- Tick what you used AI for, and say whether it wrote any of the text.
- Tick what you did yourself, such as checking the facts.
- Choose a format, copy the statement and put it where the reader expects it.

Why a specific statement works better than a vague one
People judge “I used AI” by imagining the most AI could have done. Saying exactly what it did, and what you did, leaves nothing to imagine.
I used AI tools in preparing this essay.
In preparing this essay I used ChatGPT (November 2026) for feedback on my own draft and to fix grammar and wording. I wrote all of the text myself. I checked the facts and figures against their sources, and the argument and conclusions are my own.
What a good statement says
- Which tool. By name, with the month if your reader asks for it.
- What you used it for. Feedback, grammar, an outline, a translation: the actual jobs, in plain words.
- Whether it wrote any of the text. The first thing a reader wants to know, so say it either way.
- What you did yourself. Checked the facts, confirmed the references, tested the code, made the argument.
Check the rule first
This page gives you clear wording. It does not give you permission. A course, a client contract, an employer’s policy or a journal’s instructions decide what is allowed and what has to be declared, and some set their own wording or ask to see the chat itself. Read the rule, or ask, before you rely on any statement. If the honest statement shows a use that was not allowed, the fix is to talk to the person who set the rule, not to reword the statement.
Why people hide it, and why saying it clearly helps
Hiding AI use is common and understandable. In Slack’s Workforce Index survey of 17,372 desk workers, published in November 2024, 48% said they would be uncomfortable admitting to their manager that they used AI for common workplace tasks. The fear is not baseless: experiments with 4,439 participants, published in the journal PNAS in 2025, found that people who use AI at work are rated as less competent and less motivated, and that the penalty can be offset when AI is clearly useful for the task. A statement that names the task and shows your own checking is the closest thing to that on paper.
Questions
How do I write an AI disclosure statement?
Name the tool, say what you used it for, say whether it wrote any of the text, and say what you checked or did yourself. Two to four sentences is enough. Tick the boxes on this page and it writes those sentences for you, in a form suited to a teacher, a client, a manager or a publisher.
Do I have to disclose that I used AI?
That depends on who you are writing for. Many courses and employers now have a rule, and the rules differ. If there is one, follow it. If there is none, a short statement is still the safer choice for anything submitted under your name, because it is on record before anyone asks.
Do I need to disclose using AI for grammar or spelling?
Some rules treat grammar tools like a spell checker and some ask for every use to be declared. Check yours. Where it is unclear, one line saying you used a tool for grammar and wording costs nothing and removes the doubt.
Where does the statement go?
Where the reader asks for it. For coursework that is often a cover sheet or the end of the document. Journals usually name a section. For a client, the email that delivers the work is a natural place. For readers, a short note at the end.
Is what I enter here stored or sent anywhere?
No. The statement is put together in this browser and nothing you enter is sent to thinkhard.si or anyone else. Your answers are kept in this browser so they survive a reload, and Start over removes them.
Should I keep the chat?
Yes. If anyone questions the statement, the chat shows exactly what you asked and what came back. Keep your own drafts too: version history in Google Docs or Word shows how the text was written.
