How it works
What goes in and what comes out
You give your name or brand and, optionally, what you do and what you care about. An AI model (Llama 3.1 8B, run on Cloudflare Workers AI) writes four different TikTok bios in the tone, length and language (English or Vietnamese) you choose. Each draft has its own copy button, and "Write new drafts" asks again with the same brief.
The prompt describes how people write on TikTok: Tiny and catchy: who you are and what to expect. One or two emoji.
Length
TikTok allows up to 80 characters in a bio (as of 2026). Each draft shows its count against that limit and is marked if it runs over, so you can trim it.
Short, Medium and Long aim for about 38–76, 38–76 and 38–76 characters, within any limit.
