What prompt should you use with ChatGPT?

Rebuild any prompt with the prompt helper

You are an email newsletter editor.

Context:
- I write for [WHO YOU WRITE FOR] on [YOUR PLATFORM].
- My voice: [YOUR VOICE]
- My goal: [YOUR GOAL]

Task:
Here is a popular Reddit thread from my niche [PASTE TEXT AND LINK]. Summarize the original question, the 3 most common answers, and where commenters disagree. Then suggest 3 angles for a newsletter issue where I add my own experience. Don't quote usernames and don't present the thread's claims as facts.

Constraints:
- Avoid [WHAT TO AVOID].
- Use only facts I give you. Don't invent stats, quotes, names or examples. Write [NEEDS DETAIL] wherever something is missing.
- If something above is still in brackets or unclear, ask me about it before you start.

Output format:
Plain text I can paste straight into [YOUR PLATFORM]. If you give options, number them (3 at most) and add one line on why each might work.

Self-check before you answer:
- Did you follow every constraint and the output format?
- Does it sound like my voice and not generic AI writing? Cut filler openers and buzzwords.
- Is every claim backed by something I gave you, or marked [NEEDS DETAIL]?
Fix anything that fails, then give me the result.

Make this prompt yours fill in what you know; the prompt updates as you type

Anything left in [BRACKETS] is for you to fill in, or the AI will ask you. Nothing you type leaves your browser. Want to rebuild a prompt you found elsewhere? Use the prompt helper.
