An Instagram caption generator from text takes a passage you select—a quote, a stat, or a story beat—and turns it into a caption draft that fits Instagram: conversational tone, line breaks, and space for hashtags. You get a starting point instead of a blank box.
What caption generators do
Caption generators use your input text to produce a draft tailored to Instagram: length, tone, and structure that work in the feed. You select or paste the source, the tool suggests a caption, and you edit for your voice and add hashtags. The value is speed and a consistent starting point, not a final post—you still choose what to use and how to tweak it.
