How does the AI write captions?
You provide a brief — the topic, vibe, and any key details — and the AI drafts captions that follow Instagram's casual tone, opening with a hook and closing with a clear call to action. You can regenerate until one fits.
Can I match my own brand voice?
Yes. Add notes about your tone, audience, and recurring phrases to your brief and the generator will reflect that voice across the captions it writes.
