Struggling to keep your ideas organized and accessible?
Your scattered notes across multiple apps are making you miss connections between your best ideas. You're wasting precious time searching for that perfect reference or insight you know you saved… somewhere.
This mental chaos is killing your productivity and creativity. Every blank page feels like starting from scratch, even though you've already done the research.
Kortex AI solves this nightmare by unifying your second brain in one powerful workspace. With kAI assistant, interconnected notes, and powerful search, you'll never lose an idea again. It's the all-in-one solution for writers, creators, and knowledge workers who want to transform scattered thoughts into brilliant content.
What is Kortex?
Kortex AI is a digital workspace that works like a “second brain” for writers and knowledge workers. It combines note-taking, content creation, and knowledge management in one platform. Kortex uses AI technology to organize information, generate content, and find connections between your materials. It includes multiple AI models in one place, letting users cancel other AI subscriptions. The platform can chat with your documents, summarize content, and provide writing assistance. Users can store documents, import highlights from Readwise, and capture YouTube video transcripts for easy reference
Kortex's built-in AI assistant helps transform rough ideas into polished content. Users can toggle kAI with a simple “Tab” command to expand notes into comprehensive documents, get writing suggestions, or synthesize information from multiple sources. The platform integrates multiple AI models, allowing users to maintain access to powerful language processing capabilities.
The platform employs a second-brain approach to knowledge management, allowing users to create connections between documents, notes, and highlights. This interconnected structure helps surface relevant information when needed, preventing ideas from getting lost in isolation. Users can connect documents, captures, elements, and highlights and have them all open in one clean interface.
Kortex includes a robust library for storing and organizing highlights from various sources including PDFs, books, articles, and more. The platform supports Readwise integration, with native Kindle highlights, web clipper, and audio highlighter features in development. This creates a simple and searchable library view for all your highlights.
Kortex allows users to search by tags, related words, document contents, captures, elements, and highlights. This makes finding specific information much easier without needing to remember exact phrases. This advanced searchability ensures you never lose an idea again.
Build templates, outlines, and guide your writing with Kortex Elements. This feature has become an instant “must have” for note-takers and writers, helping eliminate writer's block by providing structure to the writing process. Elements help organize information in a structured but flexible manner.
Kortex allows users to export files as markdown, ensuring they never feel locked into the platform. Users can also share individual documents and templates with others or create collaborative workspaces. This flexibility lets you own your knowledge and easily collaborate with others.
Organize your documents, captures, and highlights to find them at the click of a button. Then, open them up to reference while you write. This helps avoid “Note Taker's Chaos” and keeps your digital workspace clean and efficient.
Users can paste YouTube links to automatically capture video transcripts, making it easy to reference and incorporate information from video content. Future updates will expand this capability to other types of content, enhancing the platform's versatility.
