If you've opened a prompt here, you've seen words in square brackets, like [BRAND NAME] or [AUDIENCE]. Those are variables. You type in your own details and the prompt rewrites itself.

Simple idea. But how you fill them changes the result a lot.

Be specific, not long

"Young mums in Chattogram who shop on Facebook" is better than "everyone". It's also better than a whole paragraph. One clear line.

Use real names and numbers

We also added word suggestions while you type, so common words pop up and you can tap instead of typing. Small thing, but it's nice on a phone.
