"Klee is an AI-powered desktop application designed to enhance file, note, and task management while ensuring data privacy. Unlike cloud-based systems, Klee operates locally, safeguarding user data by minimizing external data transmission. Built with advanced AI technologies, including open-source models like Llama 3 and Mistral, Klee transforms traditional note-taking into an interactive brainstorming and productivity tool. The app's MacOS version, developed with Swift and SwiftUI, ensures seamless performance and efficiency. A standout feature of Klee is its local implementation of Retrieval-Augmented Generation (RAG), which organizes and displays files stored on the device. By segmenting documents into smaller chunks, vectorizing them, and storing them locally, Klee can quickly retrieve relevant information from a knowledge base when users ask queries. These relevant pieces are then fed into a large language model to generate insightful responses, making file and data management smoother and more intuitive. Klee's focus on on-device processing ensures users can manage files and tasks with powerful AI functionality while keeping their data completely private. This unique combination of advanced AI with enhanced privacy features makes Klee a reliable tool for secure, efficient data management. "
