Micro-agent is a lightweight, unopinionated JavaScript library designed to simplify the creation of sophisticated AI agents using large language models. It exposes core abstractions such as agents, tools, planners, and memory stores, allowing developers to assemble custom conversational flows. Agents can invoke external APIs or internal utilities as tools, enabling dynamic data retrieval and action execution. The library supports both short-term conversational memory and long-term persistent memory to maintain context across sessions. Planners orchestrate chain-of-thought processes, breaking down complex tasks into tool calls or language model queries. With configurable prompt templates and execution strategies, micro-agent adapts seamlessly to frontend web applications, Node.js services, and edge environments, providing a flexible foundation for chatbots, virtual assistants, or autonomous decision-making systems.

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.

Owl provides a developer-focused toolkit that enables the creation of autonomous AI agents capable of executing complex, multi-step tasks. At its core, Owl leverages LLMs for reasoning, augmented by a plugin system to call external APIs, execute code, and query databases. Developers define agents using a simple TypeScript API, specify toolsets, and configure memory modules to maintain state across interactions. Owl’s runtime orchestrates reasoning loops, handles tool invocation, and manages concurrency. It supports both Node.js and Deno environments, ensuring wide platform compatibility. With built-in logging, error handling, and extensibility hooks, Owl streamlines prototyping and production deployment of AI-driven workflows, chatbots, and automated assistants.
