  • Combines large language models such as OpenAI and Anthropic to support diverse AI capabilities including text classification, question-answering chains, and chatbot interactions.
  • Utilizes Pinecone vector database for vectorized storage and retrieval of documents, enhancing the accuracy and efficiency of content-based queries.
  • Built-in Google Calendar API integration for real-time schedule queries and automatic appointment creation, minimizing scheduling conflicts.
  • Supports Slack message notifications, webhook-triggered data inputs, customizable JavaScript code nodes, and user-friendly annotations to facilitate workflow understanding and maintenance.

Core Problems Addressed

  • Automatically filters and tags large volumes of emails, saving manual classification time and improving work efficiency.
  • Converts complex document contents such as PDFs into queryable vector data, enabling intelligent content-based Q&A to help users quickly obtain key information.
  • Provides intelligent scheduling and appointment management by automatically detecting free time slots, avoiding conflicts, and enhancing meeting arrangement efficiency.

Application Scenarios

  • Automated email classification and label management for corporate mailboxes, suitable for customer service, sales, and administrative staff.
  • Knowledge base construction and intelligent Q&A for documents in legal, financial, research, and other fields, accelerating information retrieval.
  • Intelligent scheduling assistant for sales, consultants, technical support, and other roles requiring frequent client or colleague meetings.
  • Internal enterprise automation for notifications and task triggers, improving team communication and collaboration efficiency.

Main Workflow Steps

  1. Intelligent Email Classification: Listens for new emails via Gmail trigger, invokes AI text classification models to analyze email content, automatically tags emails with labels such as “automation” or “music,” and sends notifications through Slack.
  2. PDF Document Processing and Q&A: Automatically downloads specified PDF documents, uses PDF loaders and recursive character splitters to segment text, generates text embeddings via OpenAI, and inserts them into the Pinecone vector database. Users submit queries through a chat interface; the system retrieves relevant vectors and combines them with GPT-4o to generate precise answers based on document content.
  3. Smart Scheduling Assistant: Receives user appointment requests via chat triggers, employs multi-turn conversations and contextual memory, queries Google Calendar API for availability, and upon confirming no conflicts, automatically creates 30-minute meeting appointments to complete intelligent schedule management.

Involved Systems and Services

  • Gmail: Email reception and label management
  • Slack: Message notifications
  • Webhook: External data input triggers
  • OpenAI GPT-4o, Anthropic models: Text classification, Q&A, and dialogue generation
  • Pinecone Vector Database: Document vector storage and retrieval
  • Google Calendar API: Schedule availability queries and appointment creation
