Chatsy: AI agents that take action, backed by a full toolkit

Hey Product Hunt! 👋 Launching Chatsy today - AI agents that actually take action, backed by a complete support toolkit. Why we built this: Yes, there are agentic chatbots out there. But most stop at tool calling. Your agent can check an order status, sure - but then what? Where's your knowledge base? Where does the conversation go when the agent can't solve it? You end up duct-taping together 3-4 different tools. We built the full stack in one platform. What you get: 🤖 Agentic AI with tool calling - Connect to your APIs with OAuth2 support. Your agent intelligently picks the right tool based on user intent. 📚 Built-in Knowledge Base CMS - Create help articles that sync with your agent in real-time. No external tools needed. 📬 Team Inbox & Ticketing - When the agent can't solve something, it escalates to your team seamlessly. Complete the loop. 🔄 Real-time data sync - Crawl websites, upload documents (PDF, DOCX), everything stays current automatically. The difference: Most platforms give you an agent with tools. We give you the complete customer support platform - from AI to human handoff, all integrated. Tech stack: Next.js 16, Vercel AI SDK, PostgreSQL + pgvector for production RAG, latest AI models. Free tier available. Try it at chatsy.app - would love feedback especially from teams managing customer support across multiple tools right now. What's your current stack look like?
