Functionary provides a declarative way to register custom tools — JavaScript functions encapsulating API calls, database queries, or business logic. It wraps an LLM interaction to analyze user prompts, determine which tools to execute, and parse the tool outputs back into conversational responses. The framework supports memory, error handling, and chaining of actions, offering hooks for pre- and post-processing. Developers can quickly spin up agents capable of dynamic function orchestration without boilerplate, enhancing control over AI-driven workflows.

Sentient is a stateful AI Agent platform designed to power non-player characters and virtual personas. It features a memory system that records events, a goal scheduling engine that plans multi-step actions, and a conversational interface for natural dialogue. Developers configure personas with customizable traits, objectives, and knowledge bases. Sentient SDKs and APIs for Unity, Unreal, JavaScript and Node.js enable seamless integration, on-premise or in the cloud, to deliver immersive, interactive digital experiences.
