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.
- Generate production-ready mechanical CAD from text or voice prompts
- Automatic PCB layout and schematic generation from prompts
- Export manufacturing files including Gerber for fabrication
- Web-based workflow accessible via browser (cloud-hosted)
- Tiered subscription plans with design quotas or unlimited usage
- 7-day free trial for new users
- Outputs industry-standard file formats compatible with CAD/EDA tools
- No public API or SDK documented on the referenced page
Best for
- Rapid hardware prototyping: Convert a product concept described in a meeting into initial mechanical CAD and PCB layouts to accelerate prototype fabrication.
- End-to-end product development: Produce both enclosure CAD and electronic schematics/PCB designs from a single prompt to speed up integration between mechanical and electrical teams.
- Electronics startup MVPs: Quickly generate manufacturable PCB layouts and Gerber files to iterate hardware MVPs without large engineering headcount.
- Enclosure and mount design: Create production-ready mechanical components and assemblies for housing PCBs and sensors based on functional requirements.
- Design iteration in meetings: Use voice prompts during reviews to request changes and receive updated CAD or PCB outputs for fast decision-making.
- Scale design output for teams: Use subscription tiers to standardize automated design generation across multiple products and designers.
- Rapid prototyping of hardware concepts by converting product descriptions to CAD and PCB designs
- Automated generation of schematics and Gerber files for small-batch manufacturing
- Designers and engineers accelerating iteration cycles by using natural-language or voice-driven design inputs
- Startups and makers producing production-ready files without full in-house CAD/EDA expertise
- Exporting designs for handoff to contract manufacturers or further refinement in standard CAD/EDA tools
Praex
Praex
Open-source AI coding copartner with its own Velox, Faber and Lucia models, available in terminal, mobile and web.
Key features
- Own Model Family: Velox II, Faber II and Lucia II are tuned and served by Praex on its own infrastructure, sized from quick edits to frontier-scale problems.
- Terminal CLI: Install with a one-line script and let the agent read files, run commands, edit code and verify tests directly in your terminal.
- Cross-Device Sessions: Start a task in the terminal, steer it from your phone and review it on the web with the same agent, memory and session.
- Bring Your Own Keys: Run Praex on any model with your own API keys or hardware at no extra cost.
- Open-Source Core: The CLI is an MIT-licensed fork of opencode, so the agent harness can be inspected and modified.
- No Sign-Up Chat: Start chatting on the web with the free Velox II model without creating an account.
Best for
- Fixing Failing Builds: Hand the agent a broken deploy and let it read configs, run tests and patch source until tests pass.
- Everyday Quick Edits: Use the free Velox II model for instant answers and small code changes in the terminal.
- Deep Reasoning Tasks: Escalate to Faber II on Pro for complex coding and multi-step reasoning.
- Mobile Task Steering: Kick off a refactor at your desk and monitor or redirect it from your phone.
- Self-Hosted Workflows: Point the CLI at your own models or keys to keep code on infrastructure you control.
