よくある質問
Can colleges or employers tell if my cover letter is AI?+
Some screen with AI detectors, but a score is not proof and false positives happen. Generic, voiceless writing is a bigger giveaway to human readers than any tool.
Should I check my cover letter before submitting?+
It's a useful gut check — it shows which lines read as generic so you can rewrite them in your own voice. Keep your drafts as evidence of your process.
Is using AI for a cover letter cheating?+
Using AI to brainstorm is usually fine; submitting AI-written content where it's prohibited is not. Check each application's policy and keep the final words your own.
