A startup named Cove, founded by ex-Google Maps engineers, has secured $6 million from Sequoia Capital to develop an AI-driven infinite board interface for collaborative tasks. The platform allows users to generate multiple responses from a single AI prompt, enhancing project planning, writing, and research. Users can interact with a chatbot, edit generated cards, and share boards with collaborators, similar to Google Docs. Cove is currently web-based with a limit of 100 free cards, offering unlimited access for $10 per month. The founders aim to revolutionize human-AI collaboration.
