Common Questions
1. What makes ZeroEntropy different from traditional search engines?
Traditional search uses static keyword or semantic matching. ZeroEntropy is optimized for retrieval quality out of the box — combining dense, sparse, and reranked relevance in a single API. We treat every query as a learning opportunity: • You get state-of-the-art relevance, not a bag-of-words match. • You don’t need to tune BM25 weights, vector thresholds, or rerank configs — we handle that. • You don’t maintain an infra Frankenstein of vector DBs, LLMs, pipelines — we unify it.
2. Does ZeroEntropy handle PDF parsing and chunking?
3. How does ZeroEntropy process the data I send? Can you deploy on premise?
4. Is there a free trial?
5. What is the query latency?
6. What kind of support is offered?
7. Is it easy to integrate with my product?
