iOrchestra Vibe Engineering
iOrchestra
Design hardware from text or voice prompts to production-ready mechanical CAD, PCB layouts, schematics, and manufacturing files.
Key features
- Prompt-to-Production Outputs: Transforms text or voice prompts directly into production-oriented design artifacts such as mechanical CAD, PCB layouts, schematics, and Gerber/manufacturing files to shorten design cycles.
- Mechanical CAD Generation: Produces production-ready mechanical CAD models and assemblies usable in standard CAD workflows, enabling rapid creation of enclosures, mounts, and mechanical components from high-level requirements.
- PCB Layout and Schematic Automation: Automatically generates electronic schematics and places/routs PCB layouts suitable for manufacturing, reducing manual PCB design effort.
- Manufacturing File Export: Exports manufacturing-ready files (including Gerber outputs) so designs can be handed off to PCB fabrication and EMS partners without manual rework.
- Voice and Text Interaction: Accepts both voice and text prompts to describe product requirements, enabling fast ideation and hands-free design iteration during meetings or on-the-go.
- Iterative Refinement: Supports refinement cycles where designers adjust requirements via prompts and receive updated CAD/PCB outputs, accelerating revisions and concept exploration.
- Subscription Quota Management: Plan-based quotas and limits (e.g., PLUS with 100 designs/month or MAX unlimited) to match team scale and output needs.
