About the Social Media Bio Generator

A profile bio is the shortest piece of copy you will ever write and one of the most read. It has to say who you are, what you do and why anyone should follow, inside a character limit that differs on every platform.

Enter your name or brand, what you do, and which platform the bio is for, and Instant mode writes six bios built to that platform's real limit — 150 characters on Instagram, 160 on X, 80 on TikTok, 101 for a Facebook Page, 220 for a LinkedIn headline — with the character count shown next to each one.

Instant mode never touches the network. AI mode is optional, sends only the fields you filled in, and runs on a Generate click rather than as you type.
