🚀 Key Features

🌊 5-Pass Neural Synthesis

Axiom uses a multi-agent waterfall to synthesize knowledge across 5 distinct layers:

• Layer 1: Structural Taxonomy: Identifies core entities, bylines, and technical metadata.
• Layer 2: Conceptual Deep-Dive: Isolates the "load-bearing" ideas and technical frameworks.
• Layer 3: Dialectical Perspectives: Reconciles diverse examples, counter-arguments, and edge cases.
• Layer 4: Semantic Connections: Maps the content to your existing knowledge graph and real-world apps.
• Layer 5: Generative Learning: Crafts actionable paths, retrieval-augmented Q&A, and follow-up prompts.

📁 Hierarchical Organization

Axiom doesn't just create notes; it builds a structured knowledge graph. Based on the AI's taxonomy analysis, notes are automatically filed into deep hierarchies with corresponding Maps of Content (MOCs):

MOCs/
├── Biology/
│   └── Cell Biology/
│       └── 00-Cell Biology MOC.md
├── Business/
│   ├── Entrepreneurship/
│   ├── Finance & Investment/
│   ├── Leadership/
│   └── Marketing/
└── Venture Capital/
    ├── 00-Venture Capital MOC.md
    └── ...

⚖️ Precision Tokenomics

• Usage Heartbeats: Visual feedback for token count and cost increments for every pass.
• Tiered Pricing: Accurately tracks costs across modern model tiers (Flash, Pro).
• Atomic Recording: Usage is persisted immediately after every pass to ensure accurate tracking.
