Kortex
AI-powered knowledge management and writing platform combining networked notes, research capture, and AI writing assistance for content creators and writers.
Kortex is an all-in-one knowledge management and writing tool designed for content creators, newsletter writers, and educators who need to organize research and produce content from a single workspace. Notes are connected via bidirectional links to build a personal knowledge graph, and the AI writing assistant generates drafts and suggestions grounded in the user's own saved content rather than generic internet data. Highlights and clips from articles, books, and web pages are saved with source attribution and become searchable nodes in the knowledge graph. Kortex is built by Dan Koe's team and has attracted a strong creator audience looking for a writing-first alternative to Notion for content workflows.
Key Features
- Connected notes with bidirectional linking for building a personal knowledge graph from saved ideas and research
- AI writing assistant trained on the user's own saved notes for context-aware, personalized content generation
- Highlight and clip tool for saving passages from articles, books, and web pages with full source attribution
- Daily notes structure for capturing fleeting ideas and automatically linking them to related project notes
- Content creation workspace combining research notes, outline drafts, and final writing in a single document flow
- Template library for newsletters, thread outlines, course structures, and content brief formats
- Publishing export to Substack, Medium, and Notion for distributing finished content without reformatting
Use Cases
- Newsletter writers organizing weekly research captures into a connected library before drafting each issue
- Content creators using AI writing grounded in personal research rather than generic prompts for original output
- Educators building a knowledge base of concepts that surfaces relevant past notes while creating new course content
- Bloggers and writers building a second brain that accumulates and connects ideas over months and years
Pros
- AI generates from your own notes - writing assistance grounded in personal knowledge produces more original output
- Bidirectional linking creates emergent connections between ideas that linear notes apps like Apple Notes cannot surface
- End-to-end from research capture to publishing export in one tool reduces context switching across Notion, docs, and CMS
Cons
- Most valuable after months of consistent note-taking - new users see limited AI benefit until a knowledge base is built
- Publishing integrations less capable than dedicated CMS tools like Ghost for full-control content distribution
- Free plan restricts AI writing credits to a limited quota - active creators need the paid plan for regular generation
