How it works
AI caption generator: how it works
An AI caption generator writes the post's text from a prompt or context you provide — it can be a free-form prompt, a photo, or, with more complete tools, a business briefing saved ahead of time. The quality of the result depends directly on the quality of that context.
In practice
3 ways to give the AI context
A free-form prompt, every time
You write what you want in a text box for every single post. Quick to start, but repetitive — tone can drift from post to post.
From a photo
The AI describes what it sees in the image and suggests a caption. Useful, but does not always capture the brand's voice.
From a saved briefing
You describe your business, your audience, and your tone once — the AI uses that for every caption it generates, no repeated prompt needed.
How VitrinaFlow helps
The briefing goes in once, the caption comes out every day
VitrinaFlow uses the third approach: your business briefing (product, target audience, tone of voice) is filled in once, and the AI generates the caption — and the image — every day following that briefing, with no prompt to type in day to day.
