What is the character limit for an Instagram bio?

Instagram bios are capped at 150 characters. The AI Bio Generator respects this limit on every Instagram variant. Emojis count as 2 characters in many cases — the generator factors that in.

What is the character limit for a LinkedIn headline?

LinkedIn headlines are capped at 220 characters. The full About section allows up to 2,600 characters, but the first 220 are what people see in search and feed — the AI Bio Generator optimises the hook for that window.

Should I include emojis in my bio?

Depends on the platform. Instagram and TikTok bios feel natural with 1-3 emojis. LinkedIn bios should use them very sparingly (none is often best for executives). Twitter sits in between. The AI Bio Generator applies the right convention per platform.

Yes. The AI Bio Generator is completely free, no signup, no daily limits beyond standard abuse protection.

Role, niche, vibe, notable proof points. The more specific, the better.

What makes a good social-media bio?

A good bio answers three questions in under 200 characters: who you are, what you do, and why someone should care. On Instagram and TikTok the audience scans in 1-2 seconds; on LinkedIn they will read in full. The best bios adapt voice to the platform.

Platform-specific tips

Instagram (150 chars): lead with one strong identifier (job + niche), add a proof point or vibe, end with a CTA or link. Emojis welcome but max 3.
LinkedIn headline (220 chars):role + company + what you actually help people with. Avoid jargon. Avoid “passionate about” — show specifics instead.
Twitter / X (160 chars): sharp identity line + one credibility marker. Personal voice over corporate. One link beats two.
TikTok (80 chars): very tight. Identity + niche + hook is the most you can fit. Emojis are common.
YouTube (1000 chars):can be longer, but lead with the value-prop hook in the first 100 chars (that’s what shows in search previews).

Why 5 variations?

Picking the right bio is taste-dependent. The AI Bio Generator returns 5 angles — credentialled, witty, mission-driven, numbers-led, and CTA-driven — so you can pick (or remix) the one that sounds most like you. Same input, very different vibes.
