What it solves

It provides a Java client library for interacting with the Dify platform, allowing Java developers to integrate generative AI capabilities—such as chatbots, text generation, and knowledge bases—into their own applications without writing raw API calls.

How it works

The library acts as a wrapper around Dify's APIs, offering specialized clients for different application types (Chat, Completion, Chatflow, Workflow, and Datasets). It supports two primary interaction modes: blocking (synchronous) and streaming (asynchronous via callbacks), and includes built-in support for session management, file handling, and RAG pipeline orchestration.

Who it’s for

Java developers who want to build AI-powered applications using the Dify platform and need a type-safe, structured SDK to manage AI workflows and knowledge bases.

Highlights

• Comprehensive App Support: Dedicated clients for chat, text completion, orchestrated chatflows, and general workflows.
• Flexible Interaction: Supports both blocking responses and real-time streaming for "typewriter" effects.
• Knowledge Base Management: Full lifecycle support for datasets, including document uploading, segment management, and semantic retrieval.
• Advanced Workflow Features: Integration for human-in-the-loop (Human Input) nodes and support for separate reasoning streams (reasoning_chunk).
• Multimedia Capabilities: Built-in support for speech-to-text and text-to-speech conversions.
