How it works
What goes in and what comes out
You give your name or brand and a few interests; you can rule out digits. An AI model (Llama 3.1 8B, run on Cloudflare Workers AI) writes five different TikTok usernames. 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: Catchy and easy to say out loud.
TikTok's rules
A TikTok username must be 2 to 24 characters: letters, numbers, underscores and periods, not ending in a period.
Every suggestion is cleaned before you see it: accents are folded to plain letters (so Vietnamese names work), spaces become the separator the rules allow, characters the platform refuses are dropped, and anything that still breaks the rules is thrown away.
