Jina AI

The Jina AI website presents a search foundation offering built around multilingual and multimodal search models. The page highlights a Reader API that converts any URL to Markdown for grounding LLMs (accessed by prepending r.jina.ai to a URL), an Embeddings offering described as multimodal and multilingual, and a Reranker described as maximizing search relevance. It also references a search endpoint (s.jina.ai) that returns web search results, an MCP server option for using its APIs in LLMs, a CLI, and an API key with billing. The page lists many Reader parameters such as CSS selectors for extraction, caching controls, proxy and cookie options, and JSON response formatting. It also lists research publications on embedding, reranker, and vision-language models.
