Multi-Agent Conversation
This workflow enables simultaneous conversations between users and multiple AI agents, supporting personalized configurations for each agent's name, instructions, and language model. Users can mention specific agents using @, allowing the system to dynamically invoke multiple agents, avoiding the creation of duplicate nodes, and supporting multi-turn dialogue memory to enhance the coherence of interactions. It is suitable for scenarios such as intelligent Q&A, decision support, and education and training, meeting complex and diverse interaction needs.
Intelligent Q&A and Citation Generation Based on File Content
This workflow achieves efficient information retrieval and intelligent Q&A by automatically downloading specified files from Google Drive and splitting their content into manageable text blocks. Users can ask questions through a chat interface, and the system quickly searches for relevant content using a vector database and OpenAI models, generating accurate answers along with citations. This process significantly enhances the efficiency of document information acquisition and the credibility of answers, making it suitable for various scenarios such as academic research, enterprise knowledge management, and customer support.
Daily Cartoon (w/ AI Translate)
This workflow automatically retrieves "Calvin and Hobbes" comics daily, extracts image links, and uses AI to translate the comic dialogues into English and Korean. Finally, the comics, complete with original text and translations, are automatically pushed to a Discord channel, allowing users to access the latest content in real time. This process eliminates the hassle of manually visiting websites and enables intelligent sharing of multilingual comics, making it suitable for comic enthusiasts, content operators, and language learners.
Multimodal Image Content Embedding and Vector Search Workflow
This workflow automatically downloads images from Google Drive, extracts color information and semantic keywords, and combines them with advanced multimodal AI models to generate embedded documents stored in a memory vector database. It supports text-based image vector searches. This solution addresses the inefficiencies and inaccuracies of traditional image search methods and is suitable for scenarios such as digital asset management, e-commerce recommendations, and media classification, enhancing the intelligence of image management and retrieval.
Summarize YouTube Videos (Automated YouTube Video Content Summarization)
This workflow can automatically retrieve the transcription text of YouTube videos and utilize artificial intelligence technology to extract key points, generating a concise text summary. Through this process, users can quickly grasp the essential information from the video, saving time on watching lengthy videos. It is suitable for content creators, researchers, and professionals, helping them efficiently acquire and manage valuable information, enabling rapid conversion and application of knowledge.
LLM Chaining Examples
This workflow demonstrates how to analyze and process web content step by step through multiple chained calls to a large language model. Users can choose sequential, iterative, or parallel processing methods to meet different scenario requirements. It supports context memory management to enhance conversational continuity and integrates with external systems via a Webhook interface. It is suitable for automatic web content analysis, intelligent assistants, and complex question-answering systems, catering to both beginners and advanced users' expansion needs.
Auto Categorize WordPress Template
This workflow utilizes artificial intelligence technology to automatically assign primary categories to WordPress blog posts, significantly enhancing content management efficiency. It addresses the time-consuming and error-prone issues of traditional manual categorization, making it suitable for content operators and website administrators, especially when managing a large number of articles.
