FAQs
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?
This is the answer.
3. How does ZeroEntropy process the data I send? Can you deploy on premise?
We take security very seriously. ZeroEntropy is SOC 2 Type 2 and HIPAA compliant.
We also offer a fully managed EU-based instance to comply with regional boundaries.
For additional control, ZeroEntropy can be deployed on-premise.
4. Is there a free trial?
Yes. You can try our Starter plan free for two weeks, including 1,000 queries and 1M tokens of ingestion.
5. What is the query latency?
Here is a table summarizing latencies for both the search engine and reranker:
Reranker (75 kb payload) | Retrieval API (205MB of UTF8 bytes) | Retrieval API + Reranker | |
|---|---|---|---|
p50 | 129.7 ms | 156.1 ms | 220.5 ms |
p90 | 146.1 ms | 181.4 ms | 253.1 ms |
p99 | 193.9 ms | 276.2 ms | 320.2 ms |
6. What kind of support is offered?
We offer standard support for Starter and Teams plans, and advanced white-glove onboarding and integration support for Enterprise clients.
You can also join our Slack community to get support.
7. Is it easy to integrate with my product?
Yes. Our developer-first documentation, API reference, and Slack community make integration seamless.
