Agentic AI studio

We design and ship agentic AI systems that build real software.

Darren Labs builds tools that remove repetitive work, starting with open AI models and engineering software you can use today.

The story

The studio builds itself as you scroll.

One scene, four moments. Scroll to build it.

Plate IThe studio builds itself

Three zones: AI Studio · VoltWorks Power · AI Architecture Patterns. Drag to orbit · Scroll builds the scene · Select an item for a short description.

01 · Studio

One person directs. Agents build. A human verifies.

Darren sets the goal and defines what “good” looks like. Agents build the first version. Darren reviews the result.

Brief → Generate → Verify → Fix → Re-verify.

02 · VoltWorks Power

Power-system CAD without repetitive drafting.

Engineers design with confidence. Newcomers can follow the drawings.

True-scale 3D: 1 unit = 1 m; inspect equipment at full size.
Single-line-diagram (SLD) builder with an integrated 3D view.
Engineering calculators that show their work: IEC 60364 and 60909, IEEE 1584-2018, NFPA 70E.

03 · AI Architecture Patterns

Diagrams, trade-offs, judgment.

A visual design library for AI systems: what works, what it costs, and when not to use it.

Visual patterns in plain language.
Measured trade-offs: gains, costs, and failure modes.
Runnable demos: try the idea instead of only reading about it.

04 · Verify loop

Brief, build, check with our own eyes, fix, check again.

That loop built this site, VoltWorks, and MEP Suits. Nothing goes live unchecked.

Open models, free to run.

Two models, two jobs. Run them on your own machine with Ollama. No account, no fee.

Wowo7b

For notes and first drafts. Turn a rough site note into a readable checklist, or a messy drawing note into a draft you can edit.

Engineering tools you can open now.

Built by an engineer, for the people who do the work.

Free

VoltWorks Power

Power-system CAD without repetitive drafting: calculators that show their work, a single-line-diagram builder, and a true-scale 3D substation viewer.

Open VoltWorks Power

Free

MEP Suits

Building-services calculators and a live 3D system viewer for plant-room work. Every tool shows its method and checks against published design bands.

Open MEP Suits

Free

Omni Eyes View

A live globe of aircraft, vessels, satellites, and CCTV layers, free to explore.

Open Omni Eyes

How we work.

One loop, for everything we ship.

Brief

Define what good looks like, and what the result must not do.

Build

Agents build the first version. Humans review it, not just approve it.

Verify

Check it with our own eyes, fix what fails, and check again before it goes live.

About

Darren Labs was founded by Darren Lieu, a CAD designer in building services. He sets the direction, agents build the first version, and he checks the result before it goes live.
