Captioni – The AI Captions Generator for Social Creators

Captioni is an AI-powered tool designed for Instagram, TikTok, and OnlyFans creators who want to grow their audience and boost engagement without wasting hours thinking of what to post.

Unlike Jasper, Copy.ai, or Writesonic — which are built for agencies and corporate marketers — Captioni focuses 100% on social-first content. Instead of generic copywriting, it generates:

Captions that match your vibe (Barbie, Edgy, Glamour, Baddie, Innocent, Funny).

Hashtags that help your content reach new audiences.

Bios that make your profile stand out.

DMs & Stories that spark conversations and conversions.

Whether you’re posting a fashion photo, a funny meme, or an OnlyFans teaser, Captioni creates short, catchy, and natural text that feels authentic — not robotic.

Why creators love Captioni

Fast & easy: Generate post-ready captions in 5 seconds.

Made for mobile: Optimized for on-the-go creators.

Affordable: Free plan included, Pro at only $29/month (vs. $99+ for big AI tools).

Creator-focused: Not for corporates — built for influencers and solo creators.

Pricing

Free → 3 generations per day

Starter → $9 (15 generations / 72h, one-time)

Pro → $29/month (unlimited)

Premium → $79/3 months

If you’re tired of staring at a blank caption box, Captioni is your creative partner — helping you post consistently, grow faster, and stay true to your personal style.
