If you're looking for something to replace Trieve, Algolia is a top contender. It offers AI-powered search infrastructure with a range of tools for fast, scalable, and easy search. That includes dynamic re-ranking based on user behavior, personalization and AI synonyms, and is good for a wide range of industries and use cases.
Another good option is Vespa, which offers a single search engine and vector database. It can handle vector search, lexical search and structured data search, and you can combine those in one query. Vespa is interesting for its ability to apply AI to large data sets and for its scalability, and it's got a free tier you can use to try it out.
If you're interested in Retrieval-Augmented Generation (RAG), Ayfie is a mature enterprise search and integration platform. It can deliver contextually relevant results, integrate with a broad range of data sources, and offer real-time insights for better decision making. The platform also has advanced security and access controls.
Last, Vectorize offers a custom RAG pipeline option. It lets developers convert unstructured data into optimized vector search indexes and offers built-in connectors to services like Hugging Face and Google Vertex. Vectorize has a range of pricing tiers, but it's a good option for companies that want to build productivity-boosting apps with large language models.
