Why 'just fix it' isn't the right instruction for proofreading
If you paste text into ChatGPT and say 'proofread this,' you'll often get back a completely rewritten version that fixes the errors but also changes your voice, your sentence structure, and sometimes your actual meaning. The 'preserve my writing style' instruction prevents that. The AI fixes what's wrong without replacing what's yours. The list of error types is the learning layer — after a few rounds of this, you'll start catching your own patterns before they need correcting.
What this prompt catches that spell-check misses
Spell-check finds misspelled words. It doesn't find correctly spelled words used incorrectly ('their' instead of 'there'), missing commas that create ambiguity, sentences that are technically grammatical but confusing, or subject-verb agreement errors. This prompt catches all of those — and the brief clarity suggestion at the end often surfaces the structural issue that was making a paragraph feel off even though every sentence was technically correct.
