Orthogonal

Orthogonal is an AI-powered workspace that allows users to manage projects, notes, and files. It explicitly states it uses AI to process documents for tasks like search queries, document creation, and editing, and that it does not use user data to train its AI models, aligning with privacy controls. It also mentions collaborative workspaces for companies and individuals, indicating multi-user collaboration. While it doesn't explicitly detail 'automated sorting rules' or 'feedback-driven refinement' as described for Dynbox, its core offering of AI-powered file management, search, and privacy aligns well with several must-have features. The 'Ask AI' and 'Add Files' features suggest AI interaction with files and cloud storage integration.
