What is Kortex?
Do you ever feel like your best ideas are scattered across different apps, notebooks, and documents? It's frustrating when you're ready to create, write, or study, but you spend more time searching for information than actually using it. You need a space where everything comes together – your thoughts, research, notes, and drafts – a place that helps you connect the dots and move from idea to finished work smoothly.
Kortex is designed to be that unified space. It brings all your ideas, notes, highlights, and writing into one interconnected environment. By combining your personal knowledge base with intelligent AI assistance, Kortex helps you capture information effortlessly, synthesize complex ideas quickly, and write with unprecedented speed and clarity, without compromising your unique creative process.

Use Cases
Crafting a Research-Driven Article: Imagine you're writing an in-depth article. Use the Kortex web clipper to save key passages from online sources directly to your highlight library. Import relevant PDFs and add your own notes and thoughts. Then, open these sources alongside your draft in the writing pane. Ask kAI to summarize complex sections or suggest connections between different points, allowing you to build your argument efficiently with all your research readily accessible.
Organizing Coursework and Study Notes: As a student, you're juggling lectures, readings, and assignments. Use Kortex to capture notes during class and save highlights from digital textbooks. Import course documents and organize them with tags. When it's time to study, ask kAI to generate summaries of specific topics based on your collected notes or even suggest a study plan pulled from your materials, making revision more focused and effective.
Planning and Drafting Creative Content: For creators, inspiration strikes at any moment. Quickly capture fleeting ideas into Kortex captures. Use Kortex Elements to build reusable templates for blog posts, social media updates, or video scripts. When writing, reference your past ideas and related notes in the side pane. You can even use kAI+ to get editing advice on your drafts or brainstorm creative angles using your existing documents as context.
Kortex offers a refreshing approach for anyone who works with ideas and words. By bringing your knowledge, notes, and writing into one connected environment and augmenting it with intelligent AI capabilities, Kortex helps you stay organized, overcome creative hurdles, and write more effectively.
