Conversational search on your unstructured data.  

Aryn brings generative AI to OpenSearch and data preparation for high-quality answers.

100% open source and built for developers.

Aryn Conversational
Search Stack


Integrated one-stop shop from data ingestion to conversational APIs, enabling developers to easily build conversational search applications and scale them to production in days instead of months. The stack includes OpenSearch, an enterprise-grade search platform, conversational APIs, and Sycamore, a new semantic data preparation system. 


Large language models (LLMs) need to be prompted with prepared, enterprise data to generate high-quality answers. The missing link is Sycamore, a robust and scalable semantic data preparation system. Sycamore uses LLMs for unlocking the semantic meaning of unstructured data and preparing it for retrieval-augmented generation (RAG) pipelines and generative AI.


The stack is 100% open source (Apache License v2.0), which gives developers the freedom to customize and build without "vendor lock-in." Easily choose and experiment with different generative AI models and customize prompts, without needing to become an expert in AI and search.




Aryn's mission is to answer questions from all of your data. Our passion is data and AI in the cloud. With the recent flurry of advances in AI, we believe that seamlessly processing and querying unstructured data is within reach. Towards this, we founded Aryn to re-imagine enterprise search.


Up to 90% of enterprise data generated is unstructured, and requires search technologies to make it useful. Today's options require significant tuning, complex data preparation, and rummaging through result sets. Instead, what if you could just ask questions of your data, and easily get accurate and crisp answers?


We use LLMs as assistants to enhance and simplify the data pipelines that comprise search stacks. Also, we provide a semantic data preparation system, Sycamore, for getting getting quality answers from LLMs and RAG pipelines. We handle the complexity of scaling, security, and manageability. And, it's all 100% open source.

Aryn (pronounced "air-in") means "high mountain." Over 90% of data today is unstructured, leaving enterprises with mountains of data that are difficult to conquer. Our goal is to help you summit that peak.
