Build custom electronics with AI — describe it, and it writes the firmware
Describe the device you want and the AI selects the right modules and explains the build step by step.
Atech writes working firmware for the ESP32 motherboard so the assembled device runs without manual coding.
Modules snap into a motherboard with no soldering; standard Arduino-compatible sensors and add-ons also work.
Inspect any kit or build in interactive 3D so you know what you are assembling before it ships.

Describe your idea and Replit builds a working app in minutes
Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
Delivers exceptional UI generation and full-stack app creation, but focuses less on traditional multi-language code editing than Replit.
