Jina AI

Reader API that converts URLs to clean markdown, plus embeddings, rerankers, and DeepSearch — now part of Elastic.

AI search APIs are the infrastructure layer that gives large language models access to current web information. Unlike traditional search engines, these APIs return semantically relevant, structured results optimized for retrieval-augmented generation (RAG) and AI agent workflows. They're essential for any AI product that needs to answer questions about the real world beyond its training data.

Editorial assessment

The Reader API (r.jina.ai) is genuinely useful — paste a URL, get clean markdown. Open-source, fast, and the embeddings/reranker models are competitive. The October 2025 Elastic acquisition changes the calculus. Integration with Elasticsearch's ecosystem is a plus, but expect Jina's standalone identity to fade over time.

Exa

Exa focuses on search rather than extraction, complementing rather than competing with Jina's Reader API.

Crawl4AI
