Social Media Post Generator
Give it the idea in a sentence, choose a tone and a format, and you get three complete posts to choose from. The generator knows each platform's length and what shows before the fold. Copy one, or schedule it and it lands in the composer ready to publish.
Results come from Claude, tuned per platform. Edit them: the best version is the one that sounds like you. We do not store what you type.
Writing for Social Media
The platform decides the shape: LinkedIn wants short lines and a first line under 12 words; X wants one idea in 280; Facebook wants under 80 characters if you can; Instagram wants a hook and line breaks.
Post formats that work in 2026
- The list: "3 things I got wrong about…": the first line names the count.
- The contrarian take: one belief, why it is wrong, what to do instead.
- The story: a specific moment, what changed, the lesson in one line.
- The question: a real one you want answered: comments follow.
- The how-to: steps, short lines, no fluff.
