Welcome to AI2U

Your knowledge. Your device. Your control.

AI2U is a revolutionary local-first knowledge management platform that puts you in control. No mandatory accounts. No cloud uploads. Just powerful tools that work instantly on your device.

What Makes AI2U Different?

🏠 Local-First Architecture

Your data lives on your device by default. It's faster, more private, and works offline. Cloud sync is optional - for when you want backup or multi-device access.

🎯 Three Ways to Work

Choose your preferred interface, or use all three with real-time sync:
- Visual Interface - Beautiful UI with list, graph, and grid views
- Developer Terminal - Lightning-fast CLI for power users
- AI Assistant - Natural language interaction with your knowledge

⚡ Real-Time Synchronization

All interfaces update instantly. Create a card in the terminal, see it appear in the UI immediately. No refresh needed.

🔒 Privacy by Design

Your data never leaves your device unless you choose
No tracking, no analytics on your content
Export everything anytime
Delete means delete

Index Cards: The Heart of AI2U

Our flagship Index Cards system transforms how you capture, organize, and retrieve knowledge.

The Philosophy

"If you can't fit your idea on a 4×6 card, you need to think harder.
Once you do, break it down into 3×5 cards."

This constraint-driven approach forces clarity and creates a natural hierarchy:
- 4×6 Master Cards - Big ideas, projects, major concepts
- 3×5 Sub Cards - Tasks, details, supporting information

Why It Works

Cognitive Load - Bite-sized information is easier to process
Hierarchical - Natural parent-child relationships
Flexible - Reorganize and link cards as understanding evolves
Searchable - Every card is instantly findable

Philosophy

Human-in-the-Loop AI

AI enhances but never replaces human judgment. You maintain control while AI handles the tedious parts.

80-20 Rule

80% of value comes from 20% of features. We focus on the essential 20% and execute it perfectly.

Constraint-Driven Design

Limitations spark creativity. The card size constraint forces clarity and conciseness.

Local-First, Cloud-Optional

Your device is the source of truth. Cloud is for convenience, not dependency.
