Blog posts are full of quotes, stats, and insights that can become Instagram captions. The step is to pull one idea, shorten it, and add your voice and a CTA.
Manual approach
Skim the blog post and note 1–3 lines that are quotable or surprising. Turn one into the center of your caption: add a short intro, the quote or stat, and a closing line or question. Match the tone of your feed. Use line breaks and maybe 3–5 hashtags. One caption per idea keeps the post focused.
One-click caption from text

You get an Instagram caption draft to copy and edit. Handy when you’re reading and want to post without rewriting from scratch. Free tier: 10 generations; paid plans for more.
