Frequently Asked Questions
Is this an AI detector?
No. It flags writing patterns from a fixed list: stock phrases, clichés, filler, hedges and dash habits. People use these phrases too, so a flag cannot prove who or what wrote a text. Never use the score to accuse anyone of using AI.
What does the tool flag?
Five kinds of pattern. AI-tells are stock words and frames such as delve into, tapestry, a testament to, not only X but also Y, and three buzz adjectives in a row. Clichés are worn-out phrases like at the end of the day. Filler is long wording like in order to. Hedges are softeners like it could be argued that. Punctuation covers long dashes and doubled marks like !!.
What does the score per 100 words mean?
It is the number of flags divided by the number of words, times 100, so long and short texts compare fairly. Under 2 is light, 2 to under 5 is noticeable and 5 or more is heavy. It measures how many listed patterns a text uses, not who wrote it or how good it is.
Where do the plain-word suggestions come from?
Many follow two public plain language guides: the GOV.UK style guide's list of words to avoid (for example leverage, robust, streamline and in order to) and the US digital.gov plain language guide (for example utilize to use, commence to start, in the event of to if). The rest is our own curated list.
Can it fix the text for me?
Yes, for most flags. Press Fix on one flag or Fix all for every automatic fix, and Undo to step back. Some patterns, like not only X but also Y, have no safe one-word fix, so they are marked rewrite by hand. Read the result once before you copy it.
Is my text uploaded or saved?
Your text is never uploaded. The checks run as rules on this page, with no AI model and no network call. The draft is saved in this browser's local storage so it survives a reload; Clear removes it, and a private window keeps nothing.
Why is the long dash flagged?
A dash now and then is fine. A dash in every paragraph is a habit that many editors cut, and a comma, colon or full stop often reads better. The tool suggests a comma; switch the Punctuation category off if you want to keep your dashes.
