The reply model is built from your captions, video transcripts, bio and past replies, so answers read like something you would actually write rather than generic bot text.
Each comment is classified as a question, praise, spam, competitor bait, negative or noise, then routed to a reply, a like, a hide or no action at all.
You pick whether a surface is optimized for clicks, reach or trust, and the tool tunes how it answers and what it hides to match that objective.
Handles Facebook Page posts, ads and live streams, Instagram professional accounts, TikTok videos and YouTube videos and ads from one dashboard.
