OxViz – Onnx Graph Analyzer

OxViz — Learn ONNX models by exploring them visually OxViz is an interactive ONNX model explorer for iPhone, iPad, and Mac that teaches you how models are built and how data flows through them. Import an .onnx file and learn model structure step‑by‑step: visualize the graph, inspect operators and tensors, trace data paths, and produce clear, shareable documentation — all locally on your device. What you can do: - Visualize model architecture: see layers, connections, and data flow in a clean native interface. - Read model internals: inspect operators, tensor shapes, initializers, attributes, parameter counts, opsets, and metadata to understand what each component does. - Trace behavior interactively: follow upstream and downstream flows from any node to learn how inputs transform into outputs. - Diagnose common issues: run the Model Health Report to identify missing shapes, disconnected nodes, duplicate names, unresolved inputs, and unusual topology so you can learn problem patterns. - Create learning materials: export graphs and editable diagrams (PDF, SVG, PNG, .drawio) and generate a professional Model Health Report PDF for class notes, presentations, or handouts. Designed for learners and practitioners - OxViz is built for ML students, educators, researchers, and developers who want a hands‑on way to learn model design and debugging without sending models to a server. - Use it to study exported onnx models, prepare presentation examples, compare expected vs actual architectures, or document designs for reports and assignments. Privacy-first, local exploration All model analysis runs on your device — no account, no uploads — so you can safely explore proprietary or sensitive models while learning. Features at a glance - Import and inspect ONNX model graphs. - View operators, inputs, outputs, tensor shapes, attributes, initializers, and parameter counts. - Search and navigate large graphs quickly. - Trace flow from any node to reveal model behavior. - Model Health Report that explains common structural problems. - Export editable diagrams and professional report PDFs for teaching or documentation. - Native iPhone and iPad interface, with compatible Mac use through the iPad app. - Automatic graph layout optimized for clarity.
