## Frequently Asked Questions

### What is Clear Tangle?
Clear Tangle is an AI-powered personal knowledge management app that captures your thoughts, automatically organizes them with AI, extracts actionable tasks, and lets you chat with your entire knowledge base using advanced language models.

### How is Clear Tangle different from Notion or Obsidian?
Unlike traditional note-taking apps, Clear Tangle is AI-native. It automatically organizes your content, extracts tasks from your notes, finds information by meaning (not just keywords), and offers a chat interface to interact with your entire knowledge base.

### What makes the desktop apps special?
The Windows and macOS native apps feature global shortcuts (Alt+Space on Windows or Option+Space on macOS) to capture thoughts instantly from any application, plus a menu bar utility for quick access to your tasks and plans without opening the full app.

### Is Clear Tangle secure and private?
Yes! Clear Tangle is designed with privacy by default. Semantic search runs locally using Transformers.js, so your most sensitive data processing happens on your device. Your data never leaves for search operations.

### Does Clear Tangle work offline?
Core capture and semantic search features work offline with local AI. Cloud AI features like advanced chat require an internet connection.
