If you're looking for something to replace Papermark, Bit.ai is a top contender. It's an AI-powered document collaboration platform with features like advanced design, powerful search and real-time collaboration. The platform supports interactive living documents, AI-powered writing and a wide range of integrations, so it's good for real-time collaboration and secure document sharing with features like trackable links and password protection.
Another contender is DocsDNA. It's geared for document analytics and collaboration, with AI-powered document analysis, multilingual support and advanced OCR abilities. It can handle lots of different document types and has strong user management and collaboration abilities, so it's good for teams that need to process and manage documents.
Dropbox is also a good option. Although it's best known for storing and sharing files, it's got features like real-time document analytics, file protection and permission controls. With several pricing tiers to accommodate different needs, Dropbox is a good all-purpose tool for collaboration and data protection.
