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 Facebook comments 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 Facebook: Warm and conversational, like talking to people you know. Emoji are fine in moderation. No hashtags.
Length
Facebook sets no hard length for a comment that we could confirm, so the counter shows a plain character count.
Short, Medium and Long aim for about 40–120, 120–250 and 250–500 characters, within any limit.
