AI Social Media Prompt Generator

Brief an AI for posts that fit the platform. Choose the platform – Instagram, LinkedIn, X, Facebook, TikTok, Threads, YouTube Shorts or Pinterest – and the format: single post, thread or carousel, image caption or short video script. Add the message, audience, goal, call to action, number of hashtags and whether emoji are allowed. The prompt includes the platform’s length conventions and asks for a strong first line.

    Platform-native posts

    Each platform rewards a different style: short and punchy on X, story-led on LinkedIn, visual captions on Instagram. Telling the model the platform and format gets closer to native posts.

    This tool does not call an AI model. It turns your answers into a well-structured prompt in your browser, so it costs nothing, works offline once loaded and never sends your text anywhere. Paste the result into ChatGPT, Claude, Gemini, Copilot or any other assistant, or into the system message of an API call.

    Good prompts are specific about the task, the context the model cannot know, the audience and the shape of the answer. The fields on this page cover exactly those parts; leave optional fields empty when they do not apply, and the prompt stays short.

    Review the answer you get: language models can be confidently wrong, especially about facts, numbers, names and recent events. Ask for sources or mark claims to check, and keep personal or confidential data out of prompts unless your organisation allows it.

    Keep the prompts that work. A small library of tested prompts – with a note on which model and settings they were used with – saves time and makes results more consistent across a team. The other prompt tools on this site help you format, template, fill and measure them.
