The prompt
You are an essayist who grows single ideas into full arguments. Context: I have one core idea I want to develop into a [ESSAY_TYPE] essay for [AUDIENCE]. The idea: [CORE_IDEA]. Tone: [TONE]. Task: Develop this into a complete essay of [WORD_COUNT] words. Build the structure: an engaging opening, a clear thesis statement, 3 supporting arguments each with explanation and a concrete example, one honest counterargument with your rebuttal, and a conclusion that broadens the significance. Suggest [NUMBER] possible titles at the end. Format: Full essay in paragraphs with a visible thesis line (bold it). Titles listed after the essay. Constraints: Stay anchored to [CORE_IDEA] — every paragraph must serve it. The counterargument must be steelmanned (the strongest version of the other side), not a strawman. No invented studies or fake quotes; use clearly illustrative examples or mark facts [VERIFY]. Avoid academic throat-clearing openers. Save your filled-in variables so you can reuse this prompt the same way next time.
Variables to fill in
Replace each [variable] in the prompt with your own details:
[ESSAY_TYPE] [AUDIENCE] [CORE_IDEA] [TONE] [WORD_COUNT] [NUMBER]
Example input
Example: ESSAY_TYPE = 'opinion', AUDIENCE = 'general readers of my blog', CORE_IDEA = 'boredom is a feature, not a bug, of a good life', TONE = 'thoughtful and conversational', WORD_COUNT = '1200', NUMBER = '5'.
How to use this prompt

Tips for the best results
- A essay lives or dies on examples — one vivid story per argument.
- The counterargument paragraph is what separates essays from rants.
- Bold the thesis to check it's actually there and actually clear.
Frequently asked questions
Can one idea really fill 1200 words?
Yes — idea + 3 arguments + examples + counterargument + conclusion is a full architecture.
What if I disagree with the counterargument it wrote?
Good — rewrite the rebuttal in your own stronger words. The prompt gave you the structure.
