Real software demo shown

Accelerate every stage of the lifecycle—from design review, to build, to manufacturing exports—using our searchable, fully interactive environment where you can click any connector, trace any net, and instantly illuminate signal paths via the integrated Data Panel.

Why Design with Termino?

Engineered to remove the weight and manual tediousness of legacy CAD software & tools.

Stop messing around making "collage Powerpoint art" in Visio, Lucidchart, Draw.io, etc.

Stop wasting time on library management.

Start building better, faster, and more reliably.
Focus on the engineering and design that matters!

Automated Interactive Diagrams

  • Eliminate Drawing Fatigue: Say goodbye to manual click-and-drag grid alignment, overlapping line routing, or coordinate adjustments.
  • Smart Auto-Layout: Manhattan routing engine automatically recalculates clean 90-degree vector paths in real-time.
  • Dynamic Iteration: Move connector blocks freely and watch all connected wire pathways recalculate instantly.
  • Intelligent Search & Filtering: Dynamically highlight and filter individual wires & signals by net name, gauge, connector, or circuit group.

Rapid Development & Iteration

  • Spreadsheet-Native: Work directly with familiar spreadsheets (CSV, Excel) rather than high-friction setups.
  • Friction-Free Updates: Modify connection data, wire attributes, and add custom columns as desired. No clunky restraints.
  • Zero Infrastructure Bloat: No heavy database installations, complex components configuration, or expensive library management required.

Build-Ready Drawings
