Caption Writer (Langflow)

What it does

Instagram Copywriter is an official Langflow starter template. You type a topic; one AI agent looks it up with a web search and writes a caption with an opening hook, emojis, a call to action and hashtags, then a second agent adds a prompt you can paste into an image generator. It writes the text only: it does not make the image or post anything. It suits people who run a brand or personal account and want a first draft grounded in current facts.

It checks the web before writing, so the caption is about what is current, and the style rules sit in a prompt you can edit to match your own voice.
