Mentbot replies to comments on your Facebook and Instagram posts and messages each commenter privately in Messenger or Instagram Direct, so a "How much?" turns into a sales chat. Keyword and hashtag rules pick the reply and can be limited to specific posts; it can also like or hide comments and sends Telegram alerts for unread customer messages. No chatbot flows to build. $9 to $49 a month by daily comment volume, every feature on every plan, 14-day free trial with no credit card.
