Almost nobody was taught how to write a formal letter, and then one day you need to complain about a faulty appliance, request a document, or push back on a bill - and the tone is genuinely hard to find.
Too soft and it reads as optional. Too aggressive and it gets filed under difficult customer. The version that works is dull and specific: what happened, what you are asking for, by when, and what you will do next. Institutions respond to structure far more reliably than to emotion, however justified the emotion is.
This prompt produces that structure, in the register you choose - formal, politely neutral, or firm. It also leaves square brackets where your details go, so nothing gets invented on your behalf.
Run it in the AIMIKA chat in Text mode.
You get a properly structured letter in the register you choose, with square brackets left wherever your details belong - so nothing about your case is invented on your behalf. Fill the brackets, check the facts, send.
What makes a formal letter work is unglamorous: dates, specifics, one clear request, and a deadline. Institutions respond to structure far more reliably than to how strongly you feel, however justified the feeling. The prompt is built around that, which is why the firm version reads as calm rather than angry - and gets answered more often.
