Build a prompt

Fill in a few boxes and your prompt builds itself as you type, ready to paste into ChatGPT, Claude, Gemini, or any other AI chat tool. Only the first box is required. The more you add, the less the AI has to guess, and guessing is where it gets creative in ways you didn't ask for.

One sentence is plenty. Start with a verb, like "write," "plan," or "explain."
The facts it can't guess: names, dates, numbers, what's already happened. Leave out anything private.
Who will read or use the result. "Me" counts.
Pick one, or type your own.
A list, a table, an email, steps? Give a rough length if it matters.
Words, topics, or habits you don't want.

What you type stays in your browser. We don't save or send it. Still, don't type passwords, account numbers, ID numbers, or health details here or into any AI tool. Swap in a placeholder like [ACCOUNT NUMBER] instead.

Your prompt

Your prompt shows up here as you type. Start with the first box.

The AI can still get things wrong, and it sounds equally sure either way. Check every name, date, number, and price before you use what it writes. You're the editor.

Paste it into your AI tool. If the answer misses, tell it what's wrong in plain words and ask again. Our guide to writing a good prompt shows how.

What each part does
  • The task tells the AI what job it's doing. Without it, it'll pick a job for you, and it rarely picks the one you meant.
  • The details are the facts only you know. The AI can't see your dishwasher, your inbox, or your calendar. Anything you leave out, it either skips or guesses.
  • The audience sets the level. A note for your boss and a note for your nine-year-old should not be the same note.
  • The tone keeps it from sounding like a press release, unless you wanted a press release.
  • The format and length stop it from writing three pages when you wanted three lines.
  • The avoid list heads off the things you'd otherwise delete by hand.
  • The last line asks it to stick to your facts and ask when something's missing, instead of filling gaps with confident fiction.
