Mane AI is an open-source, privacy-first native macOS app (2026) that builds a local AI-powered knowledge base from your documents, code, images, and audio files. Using Retrieval-Augmented Generation (RAG) with local LLMs via Ollama, it enables natural-language search, chat with citations, semantic queries across modalities (text/code + image captions + audio transcripts)—all 100% offline, no cloud, no telemetry. Built with SwiftUI frontend, NestJS backend, LanceDB vectors; supports code project auto-indexing. Ideal for developers, researchers, or anyone wanting private, on-device AI search over personal files.
