What it solves

LastChat provides a privacy-focused, highly personalized AI assistant experience for Android users. It centralizes multiple AI providers and advanced capabilities like long-term memory and code execution into a single mobile application.

How it works

The app acts as a client that connects to various AI providers. It implements a RAG-based memory system using embeddings to allow assistants to recall past conversations. For technical tasks, it integrates a Python engine (via PRoot-based Linux environments) and a QuickJS engine for JavaScript execution. It also supports the Model Context Protocol (MCP) for extended tool use and integrates web search for real-time data.

Who it’s for

Android users who want a powerful, customizable AI assistant with local data storage, multi-modal capabilities, and the ability to run code directly on their device.
