Jina AI vs Not Human Search

Jina AI provides token-billed APIs for multilingual, multimodal embeddings, a reranker for search relevance, and the Reader endpoint (r.jina.ai) that converts any URL into clean Markdown for LLM grounding. New accounts get an auto-generated API key with a ten-million-token free trial before moving to paid rate tiers (100 RPM/100K TPM free, up to 5,000 RPM/50M TPM on the top plan). Recent additions include an Elasticsearch-native inference plugin and MCP/CLI integrations for agent workflows.

Not Human Search indexes websites and MCP servers by "agentic readiness" — how easily an AI agent can interact with a site via APIs, machine-readable docs, or MCP — exposing search, per-domain reports, and a live /check crawl that returns a 7-signal readiness score. It ships a public OpenAPI spec and an llms.txt file at its API root, with anonymous access to basic queries capped at a free 10-checks-per-hour rate limit, and Stripe-billed starter/pro/scale plans for higher-volume access or commerce endpoints like score monitoring and GEO score-fix services.
