Why FaseCAD

Start sooner, no strings attached, with your AI

Project templates. Save any part of a schematic as a template and reuse it in your next project. Ships with examples: direct-on-line start, star-delta start, and digital and analog I/O cards.
Open source. GPL licence: free forever, with no paid edition and no locked features. You can read and change the code.
Easy to connect to your AI. Projects are saved as readable XML and the program also runs from the command line, so your AI assistant can read, review and edit schematics without closed plugins or extra licences.
