The Change List, Explained

See What Changed — Then Learn Why.

The checker returns your corrected text plus a change list — each fix as old → new. The rule behind each common fix is named on this page, so a repeated mistake becomes a pattern you can predict instead of a silent rewrite you accept.

What the tool actually returns

The tool makes the change visible; the page makes it learnable

The checker does not append a rule to each correction — it returns the corrected text and a change list, each fix shown as old → new. That list is the working material: it tells you exactly what moved, and the pattern behind it is named below. This order beats a textbook for one reason — the mistake being explained is your own, in your own sentence.

There is no separate mode: spelling, grammar and punctuation are corrected in one pass.

In short

Read the list for repeats, not for single fixes.

One correction is a typo. Three of the same kind in one text is a rule you do not know yet, and it is worth five minutes. Write down the repeats, find the pattern for each, and check those constructions yourself before the next send.

Best for
ESL emails, essays, cover letters, and any repeated grammar mistake you want to understand.
Not ideal for
Legal, medical, or subject-matter review; grading; and writing tasks that need a full pedagogical explanation.
Fails when
The source sentence is ambiguous or missing context. Add the surrounding sentence before deciding whether to apply a fix.

What you sent, what came back, and the rule behind the change.

Subject-verb agreement

What you sent

The list of requested changes are attached.

What came back — and the rule

“are → is”. The checker returns the corrected sentence and that change pair. The rule behind it: the subject is “list”, not “changes”, so the singular verb agrees with it.

Verb form

What you sent

We will discussing the proposal tomorrow.

What came back — and the rule

“will discussing → will be discussing”. The rule behind it: after “will”, use the base verb or “be + -ing” for a future ongoing action.

Patterns worth separating in the change list

Subject-verb agreement
The verb matches the true subject of the sentence, even when another noun sits closer to it.
Verb form
The form following an auxiliary such as “will” follows the pattern that auxiliary requires.
Punctuation
Commas and apostrophes clarify sentence boundaries and ownership; a change there is usually structural, not cosmetic.
Word choice
A grammatically valid word can still be the wrong word for your meaning, so review that pair against what you intended.

FAQ

Frequently asked questions

Does the checker write out the rule for each correction?

No, and we will not imply it does. What comes back is the corrected text plus a change list showing each replacement as old → new, so you can see exactly what moved without re-reading the whole text. The rule behind each common fix is named on this page instead. That is the honest split: the tool makes the change visible, the page makes the pattern learnable.

Is this different from a spell checker?

The underlying pass is the same one — there is no spelling-only or grammar-only mode. What differs is what you do with the result. A spelling pass ends when the text is clean; this page is about reading the change list for repeats, because three identical corrections in one text are a rule you do not know yet, not three accidents.

Is it suitable for ESL writing?

Yes, and it is arguably where the change list pays off most. Accepting a silent rewrite teaches nothing; comparing old → new pairs against the patterns described here turns each correction into something you can predict next time. Check the pattern against your intended meaning before applying a suggestion.

When is it not enough?

A correction and a named pattern cannot assess an argument, an assignment rubric, citation practice, or subject-matter accuracy. Use a teacher, editor, or domain reviewer when those are the decision-critical parts of the text.
