Write 'amplifier circuit with input and output stages' and get a schematic diagram in seconds.
Technical schematics and block diagrams are time-consuming to draw by hand. With Mermaid Chart's AI generator, you describe the system architecture or circuit in plain English — 'power supply → regulator → microcontroller → wireless module' — and get clean, editable Mermaid code rendered as a professional diagram.
From 'temperature sensor → ADC → processor → display' to a rendered diagram.
No knowledge of Mermaid syntax required.
Tweak the generated code, restyle colors and labels, export anywhere.
The generated Mermaid text IS your schematic — store it in your repo.
Describe the components and connections in natural language. AI generates Mermaid block diagram syntax which renders instantly. You can refine the text, adjust styling, or regenerate until the schematic matches your intent.
System architecture diagrams, circuit block diagrams, signal flow diagrams, network topology diagrams, and hardware interconnect overviews.
Free plan includes the full editor — no credit card required.
