The honest brief
Contextual AI

- Purpose-built for grounded, citation-backed answers
- Agentic search and research layer
- Private VPC and single-tenant deployment options
- Founding team pioneered RAG research
- Pricing is enterprise sales-led, not transparent
- Aimed at technical/regulated industries, not consumers
- Requires data and knowledge-base setup to shine
ZeroEntropy

- zerank tops several reranker benchmarks
- Cheaper than Cohere rerank
- Open-weight small model (Apache 2.0)
- Single API with Python/TS SDKs
- Multilingual across 100+ languages
