FAQ

Are these captions unique to my input? +

The captions are pre-built samples matched to your selected tone. For fully custom captions written from your brand voice, try Mani's full platform.

What is the ideal caption length per platform? +

Instagram: 150 characters for feed, up to 2200 allowed. TikTok: short and punchy, under 150. X/Twitter: under 280. LinkedIn: 100-200 for engagement. Facebook: under 80 for best reach.

Should I include hashtags in my caption? +

On Instagram and TikTok, yes. On LinkedIn, 3-5 max. On X/Twitter, 1-2 relevant ones. On Facebook, hashtags have minimal impact.

Can I edit the captions before posting? +

Absolutely. These are starting points. Personalize them with your product name, specific details, and brand language for the best results.

How is this different from ChatGPT? +

Generic AI writes generic captions. Mani's full platform learns your brand DNA first, then writes captions that sound like your team wrote them. This free tool shows the format.

Want captions that sound like your brand?

Mani learns your brand DNA and writes captions, ads, and full campaigns in your voice. Not generic AI copy.
