Quick answer: check every AI draft for five risks: vague enthusiasm, invented fit, unsupported claims, keyword stuffing, and sentences that could be sent to any company.
Mistake 1: invented motivation
AI often adds admiration for the company that you never said. Keep motivation tied to public facts or your real reason.
Mistake 2: proof without proof
Phrases like strong communicator or proven leader need evidence. Replace labels with actions, decisions, or outcomes.
Mistake 3: overpolished tone
A perfect letter can feel less believable than a specific one. Leave some directness and remove corporate filler.
Prompt
Audit this cover letter for invented motivation, unsupported claims, keyword stuffing, overpolished tone, and any sentence that could fit another company. Return fixes with reasons.
