AI Social Media Bio Generator

Generate the perfect social media bio in seconds with AI. Free bio generator for Instagram, TikTok, X/Twitter, and LinkedIn. No sign-up required.

Write a bio that fits the platform

Every platform gives you a different amount of space and a different audience. Instagram allows 150 characters, TikTok 80, X 160, and LinkedIn 220 for the headline. A bio that works on LinkedIn will get cut off on TikTok, and a playful TikTok bio can look out of place on LinkedIn.

Tell the generator what you do, who you are, a few keywords, and an optional call to action. Pick the platform and a tone, and it writes several bio options that fit the character limit. Copy the one you like, or generate again.

What makes a good bio

The strongest bios answer three questions in one glance: who you are, what someone gets from following you, and what to do next. Lead with your niche or role, add one detail that makes you specific, and end with a call to action that points at your link.

  • Four tones: professional, casual, bold, and fun
  • Platform-aware character limits for Instagram, TikTok, X, and LinkedIn
  • Multiple options per generation, so you can mix and match lines
  • Free, no account required

Make the link in your bio count

Most platforms give you exactly one clickable link. A link-in-bio page turns that single link into everything you want to share: your latest video, your shop, your newsletter, and your other socials. The bio brings people in; the link is where they go next.
