Captions That Start Conversations
A caption has one job in the first line: give people a reason to tap "more". After that, it should add value or context and end with a simple call to action, such as a question or an invitation to save the post.
Write for the platform
Instagram allows long captions, X keeps it short, LinkedIn rewards a clear first line and short paragraphs. The AI caption generator adapts to each, and you can check the final length with the Social Character Counter.
