In the crowded world of digital note‑taking and personal knowledge management (PKM), Kortex emerges as a streamlined, AI‑driven platform designed to help creators, writers, and thinkers capture, synthesize, and act upon their ideas. Combining the familiarity of Google Docs, the structure of Notion, and the power of Obsidian, Kortex promises a minimal‑friction workflow to turn scattered thoughts into meaningful output. In this review, we’ll explore what makes Kortex stand out—and where it still needs work.
Product Overview
Kortex markets itself as “The AI-Powered Second Brain”, offering a unified space for ideas, notes, highlights, and writing under one intuitive roof. It aims to simplify the creative process with AI-assisted features, smooth writing flow, and powerful searchability.
Key positioning phrases:
- “like if Google docs, Notion, and Obsidian had a baby”
- Emphasis on a single workflow: capture → create.
