What is ChatGPT?
ChatGPT is a widely used conversational assistant for everyday tasks — from rewriting emails to explaining tricky concepts.
It's a solid generalist with a big plugin and tooling ecosystem.
What is Dify?
Dify is an open-source platform for building, deploying and operating LLM-powered applications and AI agents. It aims to be a complete development platform for generative AI, combining a visual workflow builder, retrieval-augmented generation (RAG), agent capabilities, model management and observability into one tool — so teams can go from idea to production AI app without assembling a dozen separate components.
The platform's visual studio lets developers and even semi-technical users design AI applications by connecting prompts, models, data sources, tools and logic in an intuitive interface. Its built-in RAG pipeline makes it straightforward to ground AI responses in your own documents and knowledge, which is essential for accurate, trustworthy assistants and chatbots. Agent features allow the AI to use tools and take multi-step actions, while support for many different language models means you're not locked into a single provider and can choose the best or most cost-effective model for each task.
Because Dify is open source, organizations can self-host it for full control over their data and infrastructure — a major draw for companies with privacy, compliance or customization requirements — or use the cloud version for convenience. It also includes the operational essentials that production AI needs: monitoring, logging, prompt management and APIs to embed your creations into other products. This breadth makes Dify suitable for building customer-facing chatbots, internal knowledge assistants, AI workflows and agentic applications. With its blend of visual building, RAG, agents and open-source flexibility, Dify has become a popular foundation for teams that want to build real AI products quickly while retaining control. For developers and companies operationalizing generative AI, it offers a comprehensive, self-hostable platform that covers the whole journey.
