Drag, connect, simulate — Blocklang empowers engineers and researchers to build C++ & Python-powered workflows across every domain.
How It Works
Three simple steps from idea to running simulation
Drag & Drop Blocks
Design your model by dragging pre-built blocks onto the canvas and connecting them with wires.
Add Custom Logic
Write custom C++ or Python blocks — integrate AI models, OpenCV algorithms, or any domain-specific logic.
Simulate & Analyze
Run your simulation in real-time, visualize outputs, and iterate — directly in the browser.
AI-Powered Workflow Building
Claude AI is now embedded in Blocklang — describe what you need, and let the assistant build it
AI Worksheet Assistant
Open the chat panel inside any worksheet and describe your signal-processing pipeline. The assistant places blocks, connects ports, sets properties — and can create brand-new custom C++ blocks on the fly when no existing block fits.
- Auto-places & wires existing blocks
- Generates and compiles custom C++ blocks
- Powered by Claude (Anthropic) or Copilot
Bring Your Own API Key
Connect your Anthropic Claude API key from your profile settings in seconds. Your key is stored securely per-account and never shared. Switch providers or remove the key at any time.
- Stored securely per user account
- One-click connect / replace / remove
- Works alongside Microsoft Copilot
Block Generator CLI
Use the included Python CLI agent to generate complete block packages offline.
Describe a block in plain English and get a ready-to-use .json
definition and .cpp implementation in seconds.
