AI Post Generator
Free AI post generator for LinkedIn, X and Instagram: type a topic, pick a tone and get a ready-to-post caption with hashtags.
The AI Post Generator writes ready-to-publish social media posts for LinkedIn, X (Twitter) and Instagram. Type a topic, an announcement or a rough idea, choose the platform and a tone — Professional, Friendly, Bold or Funny — and press Generate. In a few seconds you get a post shaped for that platform, with hashtags included.
Each platform gets its own style. LinkedIn posts are longer and professional, with a strong opening line, short paragraphs and 3-5 hashtags. Posts for X stay under 280 characters with 1-2 hashtags, and a live character counter warns you if an edit pushes you over the limit. Instagram captions are lively, use emojis and end with 8-12 hashtags so people can discover your post.
When the text looks right, press Copy, or Regenerate for a fresh version. On the X tab, Post on X opens the X composer with your text filled in. On the LinkedIn tab you can connect your LinkedIn account once and publish directly. Instagram does not allow posting from websites, so copy the caption and paste it in the Instagram app.
The generator is free and needs no sign-up. Your topic is sent to our AI service only to write the post, and your LinkedIn connection stays in your own browser. Always read the post before publishing: check names, numbers and claims, and add your own voice so it sounds like you.
