AppAgent is an LLM-based multimodal agent framework designed to operate smartphone applications without manual scripting. It integrates screen capture, GUI element detection, OCR parsing, and natural language planning to understand app layouts and user intents. The framework issues touch events (tap, swipe, text input) through an Android device or emulator to automate workflows. Researchers and developers can customize prompts, configure LLM APIs, and extend modules to support new apps and tasks, achieving adaptive and scalable mobile automation.

LLPhant is an open-source Python framework enabling developers to create versatile LLM-driven agents. It offers built-in abstractions for tool integration (APIs, search, databases), memory management for multi-turn conversations, and customizable decision loops. With support for multiple LLM backends (OpenAI, Hugging Face, others), plugin-style components, and configuration-driven workflows, LLPhant accelerates agent development. Use it to prototype chatbots, automate tasks, or build digital assistants that leverage external tools and contextual memory without boilerplate code.
