Exabase

Exabase is the data layer for AI agents. It gives your agents persistent memory, cloud storage, and semantic search so they can remember users, store files, and retrieve context across sessions. The Memory API is a self-organizing memory system that stores facts, preferences, and events, then builds a living knowledge graph that tracks relationships, resolves contradictions, and evolves with every interaction. It's not a vector database. It's real, self-improving memory. The Resources API provides a cloud-native filesystem for agents and users. Store files, notes, bookmarks, and documents with full CRUD, folders, tags, and semantic search built in. The Bases API lets you create isolated cloud workspace instances on demand. Each one comes with its own memory, files, and search, fully controlled by your app and auditable through the API or web console. Stop building memory infrastructure from scratch. Give your agents a place to work.

Ext-Infer

Ext-Infer is a PHP 8.3+ extension designed to generate embeddings for in-process vector indexing and approximate-nearest-neighbor search. It forms the generation half of a fully local Retrieval-Augmented Generation (RAG) stack for PHP, working in tandem with ext-turbovec, which indexes and searches the embeddings. This setup eliminates the need for external vector databases, Python sidecars, or data leaving the machine, ensuring a streamlined and secure process. Key Features and Functionality: - In-Process Embedding Generation: Ext-Infer allows for the creation of vector embeddings directly within the PHP environment, facilitating efficient data processing without external dependencies. - Seamless Integration with Ext-Turbovec: Designed to work alongside ext-turbovec, Ext-Infer enables a cohesive workflow for indexing and searching embeddings, enhancing the performance of PHP applications. - Elimination of External Dependencies: By operating entirely within the PHP ecosystem, Ext-Infer removes the need for external vector databases or additional programming languages, simplifying deployment and maintenance. Primary Value and Problem Solved: Ext-Infer addresses the challenge of integrating efficient vector embedding generation within PHP applications. By providing an in-process solution, it eliminates the complexities associated with external dependencies and data transfers, offering developers a streamlined, secure, and efficient tool for implementing advanced search and retrieval functionalities directly within their PHP projects.
