👋 Click here to see quick demo!

Image search	QA chatbot	Multi-media search

Jina is geared towards building search systems for any kind of data, including text, images, audio, video and many more. With the modular design & multi-layer abstraction, you can leverage the efficient patterns to build the system by parts, or chaining them into a Flow for an end-to-end experience.

🌌 Search anything - Large-scale indexing and querying of unstructured data: video, image, long/short text, music, source code, etc.

⏱️ Save time - The design pattern of neural search systems, from zero to a production-ready system in minutes.

🍱 Own your stack - Keep an end-to-end stack ownership of your solution, avoid the integration pitfalls with fragmented, multi-vendor, generic legacy tools.

🧠 First-class AI models - First-class support for state-of-the-art AI models, easily usable and extendable with a Pythonic interface.

🌩️ Fast & cloud-ready - Decentralized architecture from day one. Scalable & cloud-native by design: enjoy containerizing, distributing, sharding, async, REST/gRPC/WebSocket.

💡 YAML Completion in PyCharm & VSCode

Developing Jina app often means writing YAML configs. We provide a JSON Schema for your IDE to enable code completion, syntax validation, members listing and displaying help text. Here is a video tutorial to walk you through the setup.

	PyCharm Click menu Preferences -> JSON Schema mappings; Add a new schema, in the Schema File or URL write https://api.jina.ai/schemas/latest.json; select JSON Schema Version 7; Add a file path pattern and link it to *.jaml and *.jina.yml.
	VSCode Install the extension: YAML Language Support by Red Hat; In IDE-level settings.json add: "yaml.schemas": { "https://api.jina.ai/schemas/latest.json": ["/*.jina.yml", "/*.jaml"], }
