Jina AI

What Jina AI is

Jina AI builds the retrieval layer rather than the chat layer. Its products include embeddings for semantic search, rerankers for ordering results, a reader that turns web pages into usable text, deep search, and small language models, all aimed at multilingual and multimodal retrieval and RAG systems.

What you can do with it

• Generate embeddings for your documents
• Rerank candidate results for relevance
• Pull web pages into a pipeline
• Run deep search over a corpus
• Build multilingual retrieval applications

Who it is for

• Developers building search products
• Teams assembling RAG pipelines
• Applications needing multilingual coverage

What to watch out for

• Retrieval quality depends on chunking and metadata strategy, not only the model
• Reading web pages inherits site terms and copyright constraints
• Free token allowances are small, so budget for real indexing work
• Embedding models differ across languages; evaluate on your own corpus
