Best For: Creators, Freelancers, Job Seekers, Online Daters
Pricing: 💯 Free — Unlimited generations, no login
Why It’s Essential
Your bio is your digital handshake — and you’ve got <1 second to impress.
Most bios are boring: “Coffee lover ☕️” or “Just being me!”
Our free AI bio generator crafts scroll-stopping bios tailored to your:
- Platform (Instagram, LinkedIn, TikTok, Tinder)

Hashtags aren’t dead — they’re smarter than ever.
Instagram posts with 9–11 hashtags get maximum engagement. TikTok videos with trending tags go viral faster. LinkedIn posts with 3–5 professional tags gain 3x more visibility.

- Select tone: Trending, Popular, Niche, or Balanced
- Get 10–20 optimized hashtags instantly — no fluff, no spam
Real Use Case
