Generator · 100% free, no signup · Updated May 2026
Bios that convert — for every platform, in one tool.
A free social media bio generator that creates concise, conversion-focused bios for Twitter, Instagram, LinkedIn, TikTok, and YouTube. Outputs format-specific variants respecting each platform's character limit and standard structure (positioning + proof + CTA).
Type your niche (what you do), your audience (who you help), and your CTA (newsletter / product / DM). The generator outputs 5 bio variants tuned to each platform: TikTok (80 chars), IG (150 chars), X (160 chars), LinkedIn (220 chars headline + 2,000-char about).

Who this is for
New creators establishing accounts across platforms and existing creators rewriting bios after a niche pivot.
The problem this solves
Most bio generators output platform-agnostic text that overruns TikTok's 80 chars and underuses LinkedIn's 220-char headline. The generator is character-count aware: it writes 5 distinct bios per platform, each fitted to that platform's real limits and conventions (TikTok line-breaks, IG hashtag-handle pattern, X compact-symbol style, LinkedIn keyword-headline pattern).
Profiles with a structured 3-element bio (positioning + proof + CTA) convert visitors to followers at approximately 2-3× the rate of free-form bios — yet only 31% of creator profiles use this structure consistently across platforms.

Frequently asked
What's the right bio structure?
Line 1: what you do for whom. Line 2: proof point (audience size, results, credentials). Line 3: CTA with link. Works for all platforms with character-count adjustments.
How long should each platform's bio be?
Twitter: 160 chars. Instagram: 150 chars. LinkedIn About: 2,600 chars (but front-load first 220). TikTok: 80 chars. YouTube: 1,000 chars (but only 100 visible on mobile).
Should I include keywords in my bio?
Yes — for LinkedIn and Twitter, where bio text is searchable. Pick 2-3 niche keywords. Avoid keyword stuffing — generic terms like "passionate" hurt more than help.
Should I mention my newsletter or paid product in bio?
Yes. Bio is the only place where every visitor sees your funnel. Lead with the free CTA (newsletter, lead magnet); paid mentions go in pinned posts.
How often should I update my bio?
Quarterly minimum. Refresh after major milestones (new product launch, audience milestone, credential update). Stale bios with outdated counts signal inactivity.
