buddy

Buddy is a native desktop application that provides non-technical users with a personal assistant featuring persistent, learning memory. According to the site, it lives on your computer and acts as your second brain, and it builds a structured memory in the background, so users do not need to manage files, write complex prompts, or learn terminal commands. It is designed for conversation: users just talk to it.

The assistant remembers across sessions, including decisions, tasks, ideas, and context. It separates two kinds of memory: user knowledge in a personal wiki and what Buddy learns about the user in its own memory. It also learns from use, with patterns, concepts, and behavior adapting through accumulated interaction rather than configuration. It can surface deadlines and dated to-dos through OS notifications.

Buddy stores all memory as plain markdown files in a local folder, with no dark databases, cloud sync, or telemetry. It supports provider independence, allowing users to switch between Anthropic, OpenAI, or Google while memory remains intact in local files. Setup is via a friendly wizard, and installers are available for macOS and Linux. Under the hood, it is built with Tauri v2, Pi SDK, and git-backed markdown.
