What platforms does this support?

Instagram, TikTok, LinkedIn, Twitter/X, and Facebook. The AI adapts the caption style, length and emoji usage to match each platforms norms.

Can I control the tone of the caption?

Yes — choose from Engaging & Fun, Professional, Inspirational, Humorous, or Minimal & Clean. Each produces noticeably different output.

Does it add hashtags too?

The caption may include a couple of natural hashtags, but for a full set use the AI Hashtag Generator tool alongside this one.

How long are the captions?

Typically 2–5 sentences — long enough to be engaging, short enough to hold attention. You can always edit to fit your style.
