Chainlit: Build AI Web Apps in Minutes

For Python developers, building a frontend for an AI app is often the most time-consuming part. Chainlit solves this by providing a beautiful, ready-to-use "ChatGPT-like" UI that you can launch with just a few lines of Python code.

Multi-Modal and Stateful

Chainlit natively supports multi-modal interactions, allowing users to upload images, PDFs, and audio files for the AI to process. It also handles session state and chat history automatically, so you can focus on building the AI logic rather than managing web sockets or database connections.

Seamless Deployment

Whether you are building a quick internal tool or a customer-facing prototype, Chainlit is designed to be deployed easily. It integrates with frameworks like LangChain, Haystack, and LlamaIndex, making it the fastest way to turn an AI script into a functional web application.
