FINAL QUALITY CHECK Before finalizing verify: - grammar is correct - spelling is correct - punctuation is appropriate - typos are removed - meaning is preserved - tone is preserved - facts were not changed - numbers were not changed - dates were not changed - names were not invented or altered - responsibilities remain accurate - deadlines remain accurate - uncertainty remains accurate - conditions remain intact - technical terms remain correct - no new information was introduced - no unsupported claims were added - ambiguous wording was not resolved by guessing - language variant is consistent - the final text reads naturally OUTPUT FORMAT: 1. Corrected Text 2. Important Changes [Only when requested.] 3. Ambiguities / Items to Verify [Only when relevant.] 4. Brief Explanation [Only when requested.] IMPORTANT: - Preserve the writer's meaning and voice. - Do not rewrite correct sentences unnecessarily. - Never invent information to complete missing context. - Never silently change facts, numbers, dates, names, responsibilities or deadlines. - Preserve uncertainty, conditions and decision status. - Flag possible factual errors rather than silently correcting them. - Keep technical terminology when appropriate. - Respect the requested English variant. - Proofread first; rewrite only to the degree requested.
Use the prompt effectively.
Choose the editing level
Use light proofreading when you only want errors corrected, or standard/thorough editing when awkward sentence structure and consistency should also be improved.
Protect critical information
Names, numbers, dates, technical terms, responsibilities and deadlines should remain unchanged unless there is a clearly identifiable language or formatting error.
Preserve your voice
The goal is not to make every document sound the same. Professional, conversational, technical and informal writing should retain the style appropriate to its audience.
Flag uncertainty instead of guessing
Ambiguous wording and possible factual errors should be highlighted for verification rather than silently changed into something the writer may not have intended.
Fix the grammar without inventing the missing cause.
Document type: Business email.
Editing level: Standard.
Tone: Professional but natural.
Original: Dear Manager, Please be informed that we have completed the stock count yesterday and found 24 pcs shortage. We are checking the transaction history and will update you once the reason is identify.
Corrected: Dear Manager, Please be informed that we completed the stock count yesterday and found a shortage of 24 pcs. We are checking the transaction history and will update you once the reason is identified.
Preserved fact: The shortage remains 24 pcs.
Preserved status: The cause is still under investigation.
Key correction: 'is identify' was corrected to 'is identified' without inventing a reason for the shortage.
Proofread without losing the writer behind the words.
Proofreading is not rewriting
If your wording already communicates the right meaning clearly, the AI should not replace it simply because another sentence sounds more sophisticated.
Protect small words with big consequences
Words such as must, may, not, only and unless can materially change responsibilities and conditions. They require more care than ordinary stylistic wording.
Ask for explanations when learning
Choose corrected text plus explanations when you want to understand recurring grammar problems rather than simply receiving a clean final version.
