Jina AI vs Perspective

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.

Perspective API, built by Google's Jigsaw team, scores text for toxicity, insults, threats, and related attributes using ML models trained on human-rated comments, returning probabilities from a JSON REST endpoint (commentanalyzer.googleapis.com). It's free and quota-gated rather than metered, but Google has announced the service will be shut down after 2026 and is only accepting quota-increase requests through February 2026. New integrations should plan for a different moderation provider before then, since Google has said it won't offer direct migration support.
