Substy AI
Unified Agency CRM
The Substy CRM serves as the central command center for your agency. It is a browser-based workspace where you can add and manage your team of human chatters with custom access levels, allowing them to chat directly from the platform. It provides a clear, real-time dashboard to monitor key performance indicators like total revenue, individual chatter response rates, and average basket size. A fundamental feature is the automatic classification of fans into categories such as Spenders, VIPs, Newbies, and Timewasters, enabling targeted communication strategies from the start.
Autonomous AI Chatbot
Unlike simple assistant tools, Substy's AI Chatbot operates 24/7 without requiring human input or supervision. It is a fully autonomous sales and engagement engine. The AI initiates and maintains natural conversations, can sell Pay-Per-View (PPV) content and bundles, handle common fan objections, and re-engage fans who have gone cold. It adapts its tone and language dynamically, supporting multiple languages to cater to a global audience, all while memorizing individual fan interactions to personalize future conversations.
Intelligent Hybrid Chat Mode
This feature is a foundational game-changer for operational efficiency. The hybrid mode allows agencies to set a specific fan spending threshold. The autonomous AI chatbot automatically handles all conversations with fans below this threshold. Human chatters are then only escalated to take over conversations with high-value VIPs and top spenders. This system ensures premium service for your most profitable fans while automating the vast majority of messages, dramatically cutting labor costs and increasing scalability.
Performance Tracking & Analytics
Substy provides detailed, real-time analytics that are crucial for informed decision-making. Managers can track the performance of every chatter and the AI system, monitoring generated revenue, conversion rates, and engagement metrics. The platform also includes functionality to create and track the performance of marketing tracking links from platforms like TikTok, Reddit, and Telegram, giving clear insight into which marketing efforts are driving fan acquisition and revenue.

Substy AI
Automating Routine Fan Engagement
Agencies can use Substy AI to handle the initial and ongoing conversations with the majority of their fan base. The AI greets new fans, answers frequently asked questions, and maintains engagement through regular, personalized messaging. This ensures no fan is left unattended, improving overall satisfaction and retention rates while freeing up human chatters from repetitive tasks.
Systematic PPV and Content Sales
The platform is fundamentally built to drive revenue. Substy's AI can be scripted and trusted to sell PPV content, offer media bundles, and send free content teasers autonomously. It follows best-practice sales scripts, handles price objections, and sends optimized upsell messages, converting conversations into sales around the clock, which directly increases the agency's average revenue per fan.
Scaling Agency Operations Efficiently
For growing agencies, managing an increasing number of creator accounts and fans can become overwhelming. Substy AI allows an agency to manage more accounts without linearly increasing its team of human chatters. By automating 90% of messages, a small team can effectively oversee a much larger portfolio, enabling scalable growth while controlling one of the largest cost centers: labor.
Optimizing Human Chatter Performance
The CRM component allows managers to monitor the performance of their human chat team with clarity. By seeing real-time data on each chatter's revenue generated, response rate, and other metrics, managers can provide targeted coaching, optimize scripts, and ensure the team is focused on the high-value VIP interactions where human nuance delivers the greatest return on investment.
