What it costs
This tool costs credits — the Generate button shows the exact price live before you run it. Credits reset daily, and a run that fails costs nothing at all.
Is what I type sent anywhere?
Yes — the text you type is sent to the AI provider that writes the captions, because it's part of the prompt. Don't paste anything confidential into it.
Does it look at my photo?
No — it only works from your written description, so the more detail you give, the more specific the caption.
