Build your own writing agent.
A personal AI writing partner that turns your raw ideas — a voice memo, a frustration, a half-formed framework — into LinkedIn posts and long-form newsletter articles that sound unmistakably like you. Not generic. Not robotic. Yours.
Set aside about 15 minutes and do it in one sitting. Prefer talking to typing? You'll be able to speak your answers. Answer in your own words — the agent is only as much "you" as what you put in.
Name your agent.
Give it a name with character — something you'll enjoy summoning. An acronym, a persona, a single evocative word.
Tip: short and distinctive works best. You'll be talking to it by name.
This one really shapes your agent — a sentence or two makes a big difference.
Meet your agent.
A few answers were light
Your prompt still works, but these sections will be thin. Go back and enrich them, or proceed and edit the prompt directly below.
Here's your finished master prompt, assembled from your answers on a proven 12-part structure. You can edit it directly — click Edit, then click into the text. Then copy or download.
Meet your agent's personality, roasted and ready. Download it as an image and upload it to LinkedIn (or screenshot it) to show the world who's writing alongside you. Tap shuffle if you want a different take.
A cleaner snapshot of your agent — handy when comparing notes with others building theirs.
Where will your agent live?
Pick the AI tool you use and follow the steps. The master prompt is the same everywhere — set it up once and your agent always writes in your voice. You can come back and add it to the others anytime.
