Preview

Proofread the text below. Fix mistakes only. Do not improve my writing.

Language and spelling variant: US English
Style guide, if any: none
Names, terms and spellings to leave exactly as written: none

Text:
{{text}}

What counts as a mistake: spelling errors, grammar errors, punctuation errors, repeated words, inconsistent capitalization, inconsistent spelling of the same term, and wrong word forms (for example affect and effect, its and it's).

What does not count, and must stay unchanged: word choice, sentence length, sentence order, tone, contractions, rhythm, jargon and anything that is merely a style preference.

Output two parts:
1. A change list as a table with the columns Original, Corrected and Reason. One row per fix, quoting enough surrounding words to find it. If a fix is debatable, mark it [optional] instead of making it.
2. The full corrected text.

If you spot something that is not a mistake but might confuse a reader, such as an unclear pronoun or a claim that contradicts another sentence, list it separately under "Not changed, worth a look" and leave the text as is.

Do not rewrite, reorder, shorten or reword anything. If there are no mistakes in a passage, say so rather than inventing changes.

1 required field is empty and will stay as a {{placeholder}} in the copied text.

How to use it

  1. Paste the text exactly as written, including awkward phrasing you like. The prompt is designed to leave it alone.
  2. List product names, people and technical terms under 'keep as is' so they are not flagged as misspellings.
  3. Scan the change list before accepting the corrected text; anything marked [optional] is yours to decide.
  4. For a longer document, proofread in sections of around 1,500 words so errors near the end are not skipped.

Example output

Illustrative only. Real answers depend on your input and the assistant you use.

Change list:

| Original | Corrected | Reason |
|---|---|---|
| "its a good fit for teams who has" | "it's a good fit for teams who have" | "it's" is a contraction; "teams" is plural so "have" |
| "recieve" | "receive" | spelling |
| "the the dashboard" | "the dashboard" | repeated word |
| "e-mail" / "email" | "email" (both places) | inconsistent spelling of the same word |
| "affects of the change" | "effects of the change" | wrong word: effects are results |
| "(Q3)" | [optional] "Q3" | parentheses are a style choice |

Not changed, worth a look: In paragraph 2, "it" could refer to the dashboard or the report.

Corrected text: (full text follows with the five fixes applied and the optional one left alone)

Tips

Proofreading is a different job from editing. If you also want the text tightened, run the edit prompt separately, so you can see which changes are mistakes and which are preferences.

Run it once more on the corrected text if the document is important. Assistants sometimes miss an error on the first pass.

The assistant does not have your house style unless you paste it. Without one, expect US English conventions or whatever variant you named.
