Kortex is built for those who want to write smarter, not harder. The platform encourages interconnected writing by allowing you to link ideas, notes, and highlights across documents.

This multi-dimensional search ensures you can always locate the ideas and references you need, even if you don’t remember the exact keywords.
Collaboration is at the core of Kortex. You can share individual documents and templates with friends, students, or teammates, or create new workspaces for group projects. Exporting your files or workspace as markdown is simple, ensuring you’re never locked into the platform. Kortex also makes it easy to duplicate documents across workspaces, streamlining your workflow and making team collaboration more efficient.
Highlights from PDFs, books, tweets, articles, and more can be saved in a clean, searchable library view. Kortex offers integration with Readwise, and native support for Kindle highlights, web clipper, and audio highlighter is coming soon. This feature ensures your most important insights are never lost or buried in disorganized documents, making it easier to reference and build upon your collected knowledge.
