Describe it.We’ll engineerthe rest.
Type what you want to make. In about a minute you get the wiring, a parts list with Indian prices, a 3D model, a printable case, the code and a build guide. Then a real engineer can sign it off, and our manufacturing partners can build it at scale.
Your first design is free. No card needed. Pro and Studio when you want more.
Works with Arduino Uno R3, Arduino Nano, ESP32 DevKit V1, Raspberry Pi Pico W, Raspberry Pi 4 Model B, Siemens S7-1200 CPU 1214C DC/DC/DC, Mitsubishi FX5U-32MT/ES, Arduino Opta WiFi.

Everything you need to build it, on one sheet.
This is the plant monitor exactly as the app makes it: wiring that matches your board’s real pins, parts you can order today, code that uses the same pins, and checks against your board’s power limits.

Then a real engineer signs it off.
Automatic checks catch wiring mistakes. A qualified engineer catches the rest: parts that won’t survive real use, safety problems and cheaper alternatives. Every finding is pinned to the exact wire or part it’s about.

Questions
Is it free to try?
Yes. Every account's first design is free, with everything a paid design has: wiring, parts with prices, the 3D model, a printable case, code and safety checks. No card needed. After that, Pro or Studio keeps you designing.
Do I need to know electronics?
No. Every project comes with a parts list you can order, a wiring diagram you can follow wire by wire, and a build guide written for first-timers. Experienced builders can ask for advanced parts and skip the hand-holding.
How do you stop the AI from getting the wiring wrong?
Every design runs through automatic electrical checks before you see it: pins that don't exist, two parts on one pin, 5 V going into 3.3 V parts, missing grounds, and loads that would overdraw the board. If a check fails, the design is sent back and fixed automatically, and anything left over is shown clearly on the safety tab.
Which boards are supported?
Arduino Uno R3, Arduino Nano, ESP32 DevKit V1, Raspberry Pi Pico W, Raspberry Pi 4 Model B, Siemens S7-1200 CPU 1214C DC/DC/DC, Mitsubishi FX5U-32MT/ES, Arduino Opta WiFi. More boards are added regularly.
Who are the engineers who review designs?
Qualified electronics engineers with professional hardware experience, vetted by our team. They check the things software can't judge: whether parts suit your real use, safety, reliability and cost. Approved designs get an Engineer verified badge.
How does manufacturing work?
Request quotes from any project. We send your parts list, wiring and enclosure to manufacturing partners that fit your quantity and needs, post their quotes side by side, and manage the order once you accept one. Sourcing costs ₹4,999, credited against your order, and order management is 5% of the order value.
Can I use it for mains (230 V) projects?
Designs stay on low-voltage DC. For anything that switches mains power we use certified modules and you should have the final wiring checked by a qualified electrician.
Can I sell what I build?
Yes. The designs and code you generate are yours to use, modify and sell.
What will you build first?
Your first design is free.
