How it works
What goes in and what comes out
You say what the post is about and add the facts, links or call to action it must include. An AI model (Llama 3.1 8B, run on Cloudflare Workers AI) writes three different Threads posts 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: Conversational and genuine, inside 500 characters. Ends with something people can reply to. One topic tag at most.
Length
Threads allows up to 500 characters in a post (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 100–250, 237–475 and 237–475 characters, within any limit.
