What is Cossistant?
Cossistant is an open-source AI and human support framework designed for React and Next.js applications. It provides a support inbox, AI agent team member, and self-learning knowledge base that crawls docs and conversations to auto-build FAQs. The framework is built to feel like part of your product rather than a separate tool, with programmable actions and custom UI capabilities.
How to use Cossistant?
- Install Cossistant in your React or Next.js app using package managers like pnpm, npm, yarn, or bun (e.g., pnpm add @cossistant/next). Configure the AI agent with custom prompts, personality, and skills. The agent answers common questions, escalates to human support when needed, and learns from team answers to improve future responses.
