Writing posts with AI: why a blank prompt box makes you explain yourself every time

AI models don't carry anything from one conversation to the next. Even services with a memory feature work by adding saved notes back into the conversation. All the model knows is what is in the prompt box at that moment.

That is why people who write social posts with AI often say the same thing: every post starts with introducing yourself again. What you write about, how you sound, which phrases you never use, what this post is based on. Leave any of that out and the draft comes back sounding like anyone could have written it.

The three things you keep typing again

• Your voice. A tool that doesn't know how you sound writes in its own voice. You either explain it in every prompt or fix the result by hand.
• Your rules. The words you avoid and the things every post has to include live only in your head.
• Your sources. The article you read last week or the note you jotted down on the train has to be found and pasted in before you can start.

None of these is hard on its own. But repeat them a few times a week across several channels and, as many people put it, explaining starts to take longer than writing. Then comes the day you skip the explaining, and that day's draft drifts further from how you actually write.

A place for it before a better prompt

The usual advice here is to write down what you keep re-explaining once, in one place, and reuse it. Keep a note with a description of your voice, a few sample posts and a list of words to avoid, and paste it in every time you write.

That works, with one weak spot: the pasting is still on you. It gets skipped on busy days, and sometimes an outdated version ends up in one channel.

In the tool I'm building, I split this into two places the tool reads on its own every time. What doesn't change from post to post goes into the brand profile: a description of your voice, up to five samples of your own writing, up to 30 banned words and up to 20 rules every post has to follow. Whatever you fill in goes into the instructions for every draft. The samples are there to match rhythm, and come with an explicit instruction not to copy them. What changes from post to post goes into material: notes, links and feeds you follow collect there, and when you add a link, the body of that page is read and attached. When you write, you pick up to five pieces of material for the post.

What still stays with you

Having the context up front doesn't make the first draft final. You still read it, edit it and decide where it goes. What shrinks is the step before that: explaining who you are to a tool you'd rather had remembered.

When you hand a post to AI, how many sentences do you type before you get to what you actually want to say?
