Caelus AI is a subscription-based web application designed to streamline user acquisition for businesses through automation. This AI tool operates 24/7, monitoring social media platforms, specifically Twitter and Reddit, for keyword mentions related to competitors, pain points, and relevant product terms. Users can customize the keywords they wish to track, enabling Caelus AI to engage potential customers effectively by auto-replying to mentions or notifying users for personal responses. The AI learns from existing posts to ensure its responses align with the user's brand tone and communication style.

The platform's cloud-based operation allows for real-time monitoring and engagement, making it a valuable assistant for businesses aiming to enhance their social media presence.
