Description
Coherence connects reading with remembering. Focus on web pages and PDFs, highlight and annotate in context, ask AI as you read, then save the content to your library and build your AI-powered knowledge base. Turn any web page or PDF into an interactive experience. Search and ask questions across what you’ve kept when you need it again. Access your knowledge base from anywhere.
