Frequently Asked Questions

Yes — but only as a starting point. Use AI to create structure, grammar, and a first draft. Then spend 10–20 minutes personalizing: verify facts, add a company-specific opener, include at least one measurable achievement, and adjust tone to match the role.
Always cross-check claims against your resume, LinkedIn, and personal records. If you can’t verify a metric, remove it or rephrase it as a qualitative achievement. Keeping a personal metrics bank helps you quickly insert verified numbers.
Recruiters aren’t looking for AI markers — they’re looking for relevance and evidence. If your letter is personalized, specific, and truthful, whether you used AI is irrelevant. Avoid generic language and fabricated claims to prevent negative impressions.
Aim for a focused 10–30 minutes. Follow a 6-step workflow: prepare a fact sheet, prompt AI strategically, verify facts, personalize tone/opening, add a human detail, and run a final ATS/grammar check.
