SmartChat

SmartChat is a complete chat platform with a plugin/extension architecture.

Folder Layout

• backend/: core SmartChat backend (auth, chat, sockets, plugin runtime)
• frontend/: SmartChat web client
• backend/plugins/chat-summarizer-plugin/: chat summarization extension plugin
• run-dev.sh: convenience script to run backend + frontend together

Plugin Extension Included

chat-summarizer-plugin adds summarization without modifying core chat routes.

Plugin endpoints:

• POST /api/plugins/chat-summarizer/private/:participantId
• POST /api/plugins/chat-summarizer/group
• GET /api/plugins/chat-summarizer/capabilities

Access model:

• Private summary: only messages between requester and selected participant
• Group summary: any authenticated user in SmartChat

npm install
cp .env.example .env

Frontend
