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 Threads 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 Threads: Friendly and personal, a line or two.
Length
Threads allows up to 150 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 40–90, 71–142 and 71–142 characters, within any limit.
