About this skill

About Formal letter drafter

Formal letters — payment demands, notices of breach, complaints — are hard to pitch at the right tone. This skill sets out the facts in date order, states your demand clearly, gives a reasonable deadline and states the next step only if you've decided on one. It stays factual and professional, lists the documents to enclose and highlights facts to verify before sending. A clear, calm letter often resolves a dispute that an angry one would escalate. To use it, paste the skill into your assistant and send the situation, the facts with dates and amounts, what you want and by when; the reply opens with “Letter”.

Formal letter drafter AI skill for Business owner / legal assistant: you paste "Client hasn't paid ₹2.4 lakh for 90 days despite 4 reminders; contract signed 12 May" and get "'Re: Outstanding payment of ₹2,40,000 under our agreement dated 12 May 2026'"
