Six stages, from description to exportable C4 diagram.
Describe your blockchain system in plain English. You can describe the components, their relationships, users, external systems, and technology choices. No technical diagram knowledge required.
The AI model parses your description to identify: system components (wallets, contracts, oracles, APIs), relationships between components, user types and their interactions, external systems and integrations, and the appropriate C4 diagram level (Context, Container, Component, or Code).
Your description is matched against a library of known blockchain architecture patterns: DeFi protocols, NFT platforms, DAOs, RWA platforms, Layer 2 solutions, bridge architectures, oracle networks, and more. Known patterns improve diagram accuracy.
A C4 model diagram is generated following Simon Brown's C4 model standard. We generate Context diagrams (system overview), Container diagrams (technical components), and Component diagrams (internal structure) depending on your input detail level.
Components are automatically labeled with appropriate blockchain technologies: Ethereum, Polygon, Solana, Chainlink, IPFS, The Graph, OpenZeppelin, and 16+ other Web3 technologies based on your description.
The generated diagram is exportable as PNG, SVG, and JSON formats. The JSON export allows re-importing into diagram tools like Miro, Lucidchart, or draw.io for further editing.
10 core architectures, with per-pattern accuracy calibration.
| Pattern | Detection | Accuracy |
|---|---|---|
| DeFi Protocol | High | |
| NFT Platform | High | |
| DAO Structure | High | |
| RWA Tokenization | High | |
| Layer 2 Rollup | Medium | |
| Cross-chain Bridge | Medium | |
| Oracle Network | Medium | |
| CEX Architecture | Medium | |
| Wallet Infrastructure | High | |
| GameFi Platform | Medium |
The Blockhertz AI Architecture Generator is a productivity tool for common patterns. Novel or highly custom systems will need manual refinement in a diagramming tool after export.
