What is it?

Raven is an AI assistant app for macOS and iOS that turns uploaded documents into interactive content. You add files to a project, then ask questions about them or request summaries, and answers are generated from the content of those files.

It extracts text from images, PDFs, audio files and video files, and transcribes audio and video so the material can be queried. Files are organized into projects and copied into a local Raven Projects folder in Documents. AI features run on Apple Foundation Models, so processing happens on the device without sending data to servers, and the AI features do not require an internet connection.

The project is built with SwiftUI and uses GRDB.swift for storage, along with Apple's Vision, Speech, PDFKit and AVFoundation frameworks. It requires macOS 26 and Xcode 26, and the project is still in active development.
