You discover that an article says 80 people attended a workshop, but the checked attendance record says 60. Editing the number is necessary. Readers who already saw the article also need a clear account of what changed, particularly if your conclusion relied on the larger number.
This is a worked example of drafting a correction notice with AI, using an invented workshop and invented figures. It complements our source-of-truth guide: that guide helps anchor a draft before publication; this one addresses a factual error after readers have encountered it.
Establish the correction before asking for wording
Start with the original sentence, the verified replacement fact, and the evidence supporting the change. Keep the distinction between registrations and attendance visible. Suppose the registration list contains 80 names, while the organiser's checked attendance record contains 60 attendees. Those are different measures, not two competing spellings of the same fact.
For this example, assume last year's comparable attendance figure was 50. The published sentence was: “Attendance rose 60%, from 50 people last year to 80 this year.” With 60 attendees this year, the increase is 10 divided by 50, or 20%. Replacing only 80 would leave a second error in the sentence.
Record the basis for the correction privately in your editorial notes. Do not paste names or personal attendance records into an AI tool. A minimal description of the verified totals and their definitions is enough for help with wording.
Repair the claim and its consequences
Corrected sentence: “Attendance rose 20%, from 50 people last year to 60 this year.”
Now check any headline, chart, caption, summary, or conclusion that used the original figures. A phrase such as “attendance surged by more than half” is no longer supported. The correction must reach the reader-facing claim, not stop at the first numeral you find.
Do not automatically say that the conclusion is unchanged. In this example, attendance still increased, but the reported size of the increase changed substantially. If the article argued that the workshop needed a larger venue based on 80 attendees, review that argument separately. Arithmetic alone cannot establish the appropriate venue.
Compare a vague notice with a useful one
Weak invented draft: “This article has been updated to improve clarity. We regret any confusion.”
That wording does not identify the factual error or help a returning reader understand the difference. “Improve clarity” could describe an ordinary style edit. Here, the published account was wrong.
Specific example notice: “Correction, September 20, 2026: An earlier version reported 80 workshop attendees and a 60% increase from last year. The verified attendance total was 60, an increase of 20% from 50 last year. The article and chart have been corrected.”
The last sentence belongs only if both the article and chart have actually been corrected. If there is no chart, remove it. If the chart is still being repaired, do not use finished language to describe pending work. A correction notice is itself a set of factual claims.
Explain the cause only when you know it
In our example, you could add: “The earlier version used registrations as the attendance total.” That is appropriate only after verifying that this was the source of the error. Knowing that there were 80 registrations does not, by itself, prove how the incorrect number entered the draft.
Avoid asking AI to supply a plausible explanation. It might invent a spreadsheet mix-up, a transcription error, or a source update. If the cause is not established, leave it out and state the known error and replacement fact. You can investigate the process without delaying an otherwise verified correction.
Also avoid blaming “the AI” as a substitute for explaining what readers need to know. Whether software helped draft the article is a separate disclosure question. The corrected measure, number, and affected conclusion remain the useful information here.
Use a prompt with explicit limits
Try: “Draft a short correction notice using only these checked facts: the original article reported 80 attendees and 60% growth; the correct figures are 60 attendees and 20% growth from 50. The article and chart have now been corrected. Date the notice September 20, 2026. Identify the previous error and replacement facts. Do not invent a cause, apology policy, review process, or claim that the conclusion is unchanged.”
Compare the result with your evidence, including the date and completion status. You can use the AIUndetectable humanizer to explore plainer wording, but preserve every number and qualification during editing. Fluency and detector scores cannot verify a correction.
Place the notice where affected readers can find it
Reuters' journalistic standards emphasize transparency about errors. For your own publication, follow its correction policy and choose a visible location on the affected article. This worked example is an editorial approach, not a claim that every publisher uses one required format.
Check any version you control that repeated the mistake, such as a newsletter web archive or downloadable handout. If an email has already been delivered, changing the website will not change that email; decide whether a follow-up is warranted by the error's significance and your publication's policy.
Before closing the task, read the live corrected sentence and notice together. Both should agree with the source and with each other. Keep the original publication date accurate, record the correction date, and retain an internal record of the change. The goal is a reader who can tell exactly what was wrong and what is now supported.
