Question: I'm looking for a platform that helps me organize and annotate research papers across multiple devices.

If you want a service to house and annotate research papers on multiple devices, Audemic Scholar is a strong contender. It transforms ordinary research PDFs into an interactive format so you can listen to papers, take notes and highlight passages on any device with a web browser. The interface has accessibility features like dyslexic font and playback speed control, and it can help you better grasp complex information.

Another good option is Enago Read, an AI-powered research assistant designed to help researchers find, read and understand papers more effectively. It includes a Reading Space for collaboration, Smart Organization for project management and Personalized Recommendations for papers you might be interested in. It also features tools like Summary Generation and Collaborative Tools for sharing and annotating literature, so it's a good choice for researchers who have to process and analyze a lot of academic material.

Unriddle is another AI tool that can help you read and research documents by asking questions and summarizing complex information. It can handle big PDF files, too, with features like automatically linking related documents, creating interactive graphs to show relationships and collaborating through shared workspaces. That makes it good for researchers who need to quickly understand and extract information from lots of documents.

Last, ChatPDF lets you use an AI interface to ask questions about PDFs and get answers and summaries. It can handle multi-file chats so you can organize files into folders and have a conversation with a group of PDFs. That can be useful for researchers who want to quickly ask questions of documents and can handle PDFs in any language.
