Flux: AI-Powered PCB Design Assistant
Flux is your AI-powered design assistant that lives in your Flux Editor projects, answers complex questions, and helps you move faster by automating PCB design tasks.
Overview
Flux is an AI-powered hardware design assistant integrated directly into Flux Editor. This custom-trained large language model (LLM) understands your schematics, components, electrical connections, and bill of materials. With Flux, you can accelerate part selection, evaluate alternatives, receive design feedback, and with your approval, make direct changes to your schematic.
Join the Flux channel in our Slack community to share your experiences and discover new use cases.
Getting Started with Flux
Access Flux through the Chat tab in the right sidebar or by right-clicking anywhere on your project canvas and selecting "Flux". For detailed guidance on using AI in your design process, see our AI-assisted PCB design tutorial.
Starting a conversation
Simply type your question or request in the Chat tab. Flux maintains context within conversation threads, allowing for natural back-and-forth exchanges about your design.
Flux may take a few seconds to respond as it processes your design information.

Project Context Access
Flux analyzes your project to provide relevant suggestions:
- Project metadata: Uses project name and description for context
- Components and netlist: Understands your circuit's structure and connections
- Part information: Accesses datasheets for compatibility and design recommendations
- Layout: Understands your projects layout with its footprints, silk and traces
- Comment locations: Recognizes the physical context of your questions
- Flux Editor documentation: Provides guidance on tool features and workflows
Flux primarily works with schematics and currently has limited understanding of PCB layout and trace positioning.
