Question: I'm looking for a research assistant tool that can process visual information and provide real-time knowledge on various topics.

The first project, xAI, provides xAI's Grok, a conversational AI that can respond to a broad range of questions in a humorous and engaging way. It accepts multimodal input, including documents, diagrams and photos, and can understand long-term context and solve problems in coding and math. Grok is useful for researchers who need help getting information, processing data and generating new ideas. It's in early beta testing, but expect it to mature with user feedback.

Another good option is Unriddle, an artificial intelligence-powered information retrieval system. It lets you read and research documents more quickly by creating an AI assistant on top of any document. Unriddle can find information, summarize complex subjects, take notes and help you draft documents. It works with more than 90 languages and can be integrated with a Chrome extension, which makes it a good choice for PhD students and R&D scientists who have to read lots of documents.

If you're looking for something more specialized that works with PDFs, check out ChatPDF. It lets you upload PDFs and then ask questions that are answered with summaries and citations to source documents. ChatPDF can handle multi-file chats, documents in any language, and powerful summaries and quick answers, which makes it good for students and researchers who have to read academic papers and other research documents.
