Just drag and drop nodes to build your own AI workflow in 5 minutes! 

Flowise It is a revolutionary low-code LLM application building tool. Developers can quickly build intelligent workflows based on large language models through a visual drag-and-drop interface. The project has received 36.7K stars on GitHub in less than a year , and is praised by developers as "Lego blocks in the AI ​​era."

// Typical application scenario code example
const  flow = {
  nodes : [
    {  type'Document Loading'params : {  path'Annual Report.pdf'  } },
    {  type'text vectorization'model'text-embedding-3-small'  },
    {  type'Question and answer chain'prompt"Summarize the key data in the document"  }
  ],
  connections : [
    {  source'Document loading'target'Text vectorization'  },
    {  source'text vectorization'target'question-answer chain'  }
  ]
}

Project Practice

Building an Intelligent Email Classifier

  1. Drag in the "Mail Receiving" node to configure the IMAP protocol
  2. Connect the "Text Classification" node to select the classification model
  3. Add "Auto Reply" node to set different scenario templates
  4. Deploy as API to access corporate email system
