About BuildSheet

Turning natural language into validated Bills of Materials — from concept to kit.

The Problem

We live in a golden age of software, but hardware is still gated. If you have an idea — a solar-powered cat feeder, a custom macro-pad, a CB750 engine rebuild — you hit a wall. You don't know which parts are compatible, where to source them, or what a real BOM looks like. That gap between "I want to build this" and "here's what to order" costs hobbyists, engineers, and small shops enormous amounts of time.

What BuildSheet Does

BuildSheet is a generative hardware platform that turns natural language into structured, sourceable Bills of Materials.

1. Architect Agent — Describe your build in plain English. BuildSheet reasons about engineering constraints and generates a valid BOM with component specs and wiring notes.
2. Sourcing Agent — Leveraging Google Shopping grounding, the agent finds real purchase links, checks stock levels, and calculates total cost across vendors.
3. Safety Auditor — Validates your BOM plan against configurable safety and compliance checks before you commit to procurement.
4. Visual Assembly View — Auto-generates an interactive block diagram showing component relationships, port types, and connection dependencies.

All outputs are draft-quality and intended to accelerate the documentation process — not replace engineering judgment. Every generated BOM should be reviewed and verified before procurement or fabrication.

The Origin

BuildSheet was built by Blake Barrett during the Google AI Hackathon 2025, starting from a real problem: documenting a Honda CB750 engine rebuild. Finding the right parts across a dozen vendors, cross-checking compatibility, and keeping a clean BOM was a full-time job on top of the actual wrenching.

The hackathon produced a working prototype. Since then, BuildSheet has grown into a production-grade web app with Firestore-backed projects, Stripe-powered subscriptions, and a full suite of export and collaboration tools.

What's Next

• Text-to-CAD — custom enclosure generation that fits your generated kit
• Community Registry — a marketplace of verified builds others can clone and order
• NHTSA recall data integration — flag parts with active safety recalls in your BOM
• Server-side backend — move from browser-only storage to full multi-device sync
