How it works
What goes in and what comes out
You paste the post you are answering and, if you like, the point you want to make. An AI model (Llama 3.1 8B, run on Cloudflare Workers AI) writes four different X replys 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 X: Punchy and quick, one clear idea per reply. At most one hashtag, usually none. A single emoji at most.
Length
X allows up to 280 characters in a reply (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 40–120, 120–250 and 133–266 characters, within any limit.
