About Substy AI
Substy is the first platform to combine a full CRM and an autonomous AI chatbot in a single system built exclusively for OnlyFans and Fanvue agencies - and today it's the most widely adopted solution on the market.
The CRM is a complete agency workspace: add your chatters with custom access levels, let them chat directly from the platform, create and track tracking links (TikTok, Reddit, Telegram), classify fans automatically into Spenders, VIPs, Newbies, and Timewasters, and monitor every chatter's performance in real time - revenue, response rate, average basket.
The AI Chatbot runs 24/7 without human input. It sells PPV, handles objections, re-engages cold fans, and adapts its tone in any language - fully autonomous, not a co-pilot.
The hybrid mode is the game changer: AI handles fans below a spend threshold, human chatters take over only for VIPs. Agencies cut costs by 25% while automating 90% of messages.
Compatible with OnlyFans and Fanvue.
