 we are laser-focused on building AI-powered tools and services that significantly boost the productivity of researchers and professionals. Every researcher or professional goes through the stages of knowledge discovery, knowledge acquisition, knowledge creation, and knowledge dissemination.

Powered with proprietary AI algorithms and a unique approach to solving problems with design and tech, RAx is set to be the default workspace for any research-heavy projects. Launched in 2019, the product connects information (Research papers, Blogs, Wiki, Books, Courses, Videos, etc.) to behaviors (reading, writing, annotating, discussing & more), opening up newer insights and opportunities in the academic space that was otherwise not possible (or not imaginable).


About the team
We are a bunch of passionate researchers, engineers, and designers who came together to build a product that can revolutionize the way any research-intensive projects are done. Reducing cognitive load and helping people to convert information into knowledge, is at the core of our mission. Our engineering team is building a scalable platform that deals with tons of data, AI processing over the data, and interactions of users from across the globe. We believe research plays a key role in making the world a better place, and we want to make it easy to approach and fun to do!
