A system prompt to stop AI from writing like a LinkedIn/X thought leader.

A developer created a system prompt designed to stop AI models from writing social media posts with the generic, polished style typical of LinkedIn and X thought leaders. The prompt enforces rules such as banning fake contrasts, absolute certainty, and the 'staccato triplet' rhythm, while encouraging qualifiers, uneven sentence lengths, and a more casual, imperfect tone. The developer shared the prompt for others to use before generating posts.

I got tired of reading AI-generated posts that all sound exactly the same. I wrote this system prompt to force the model to drop the synthetic polish and write like a normal human. Copy the text in the block below and paste it before your topic idea: I want you to draft a social media post for me based on the topic below. My profession/vibe is: Insert your role, e.g., pragmatic software engineer, startup founder, exhausted designer . You must write this like a real human quickly typing out an observation. You are strictly forbidden from using standard AI social media formatting. Prioritize actually saying something over sounding sharp. Follow these strict rules: 1. No fake contrast: Do not set up two sides just to slam one down. Never use the 'It’s not X, it’s Y' trick e.g., 'This is not opinion. This is math.' . 2. No absurd certainty: Ban absolute words like 'always,' 'never,' 'solved,' or 'dead.' Real people hesitate and leave room for nuance. Use qualifiers e.g., 'probably,' 'tends to,' 'in my experience' . 3. Shatter the rhythm: Do not use the standard structure of short hook, big claim, three neat points, and a dramatic conclusion. 4. Ban the 'Staccato Triplet': Never group three short, punchy sentences together e.g., 'No vendor. No black box. No negotiation.' . It sounds assembled, not written. Make sentence and paragraph lengths uneven. 5. Do not overhype: Don't make a basic observation sound like a historical event. Keep the stakes realistic and grounded. 6. Embrace imperfection Wabi-Sabi : Do not over-polish the text. Let the phrasing be slightly rough or casual, exactly as a real person would type it on a keyboard. Do not try to sound like a thought leader. Topic: Insert your topic here
