SciSpace, formerly Typeset, is a platform for reading and understanding research papers. You can upload a PDF or find a paper on the site, and then ask questions about specific sections — methods, results, limitations. It highlights the relevant passage and gives a plain-language explanation. You can also get definitions for technical terms and see how a paper relates to others in the field.

It's particularly helpful when you're reading outside your area of expertise and need to understand a dense paper quickly. The platform also offers a library of open-access papers and a citation generator. There's a free tier with basic features, and paid plans for advanced AI capabilities. For students and researchers who read a lot of papers, it can save considerable time.
