Builder

Turn ideas into reality: design-documents-code-services

One AI platform that carries documents, design, coding, and the running service. It reads what you upload, looks up what is missing, and only then asks.

Stack up tools, and the results still drift apart

Using different AI tools for ideas, documents, screens, and code may look fast at first, but split context leads to repeated changes and reviews.

01
Planning in one tool, documents in another
Each one works fine on its own. But the next tool knows nothing of what the last one decided. You explain the same thing four times.
02
Documents stop at a draft
A page written from one line carries no trace of thought. The reader notices first.
03
Development stops at a prototype
With no design, a fix breaks something else. With nothing recorded, you cannot hand it to the next person.
04
Months pass and there is nothing to show
A few pages and a screen that does not run. That is hard to take to the next step.

What you need is not more AI tools, but one shared standard that keeps them working together.

Start without a developer, or from where you stopped

“We have no developer”
The AI writes the design, the code and the documents. You decide what to build and check the result
“We started and stopped”
No design document needed. We read the screens and data you already have, recover the structure as it stands, and continue from where you stopped
“I don't know servers”
You never have to prepare a server. Sign up and you begin in the browser right away, and the same work continues in the desktop app if you prefer

Five steps, one place

From an idea to a working service: 8 stages

From planning through documents, code, and completion reports, every decision carries into the next stage.

Lite and Pro — through planning, design, and documents

Harness Collect

Gather public-sector and procurement notices, then pick the ones worth bidding on.

Organise the work

Turn what you want to build into a project and tasks. Every decision and result is managed here.

AI Neural Analysis

Read documents, screens, and data to understand the current structure and how they relate.

AI Design, six kinds

Define menus, data, features, permissions, and test criteria in order.

Apply company standards

Apply your company terminology, work rules, and templates to the design.

Create design documents

Create plans, specifications, and business proposals directly from the approved design.

Solo and Max — through execution and completion

Build the service

Turn the design into code and check it immediately in the browser.

Run it on your computer

Run and check the same service in the desktop app.

Create completion documents

Create completion reports and deliverables from the code and work records.

Because each stage is connected, the same standards carry into later work and documents when the design changes.

This is how it actually goes with the AI

No explanation, just the conversation. The AI reads first, looks things up, shows what it found, and then asks.

Me
[1 meeting note, 1 inventory spreadsheet attached] I need a warehouse in/out management screen.
AI
I read the meeting note and the spreadsheet. Item codes use two formats: the first 320 rows are six digits, the last 80 are eight. Page 3 of the meeting note lists “clean up old codes” as an agenda item with no decision.
AI
This has to be settled before any screen. Unify on eight digits, or accept both? Which?
Me
Eight digits. Keep the old codes for reference only.
AI
Then the item table gets a separate “old code” column and the input screen accepts eight digits only. Permissions follow the note: warehouse team enters, purchasing team views. Writing the design draft.

Plausible documents you cannot use are the market's complaint. Asking instead of inventing is how this product works.

Documents come from two places

Work documents written from your company material become the raw material for the design; plans and specifications then come from the approved design, and completion reports from the actual code and work records. Neither is rewritten separately.

What documents are based on

Design documents and business plans

Created from the approved screen, data, and work standards.

Completion reports and deliverables

Created from the actual code and work records, so uncompleted work does not appear in the report.

How documents are created

Reads, looks up, then asks

Upload your material and the AI first tells you what it read and what it found, then asks only what the material does not answer.

Tables, diagrams, and charts included

Build organisation charts, process diagrams, and charts directly in the document.

Written to your company template

Upload a reference template and its tables and fields are filled in, including HWP forms.

Files ready to use

Word, PowerPoint, Excel, HWP

Review, share, or submit the files right away. Quality is checked before export.

Two things always stay in the draft

Needs confirmation

Numbers without evidence stay blank

Market size, revenue estimates, transaction counts: values not in your material are not invented but marked “needs confirmation”. Filling them in is a person's job.

Source

Every item shows where it came from

Each item is tagged with the document or conversation it came from. When a reviewer asks, you can answer on the spot.

How a design becomes a working service

We turn a design carrying your company standards into work instructions, build the code, then check it against those same standards.

1
Understand the current structure
Read documents, screens, and data to understand what is connected and how.
2
Set the build standards
Define menus, data, features, permissions, and test criteria for what will be built.
3
Create AI work instructions
Add your terminology, work rules, and design standards to a request so AI can act on it clearly.
4
Build and check the code
Build code from the work instruction and check the result immediately in the browser.
5
Review it against the standards
Check the code against the design and company standards, then show what needs revision and why.

AI Harness is a structure that governs and controls AI so it can work safely and predictably.

Company data and AI work are processed in separate places

Company materials are read and analysed in a domestic cloud; external AI is used only to create code and documents.

Store and search company materials — domestic cloud

Source documents are processed and stored on NAVER Cloud Platform GPUs, then retrieved there when needed.

AI Neural Analysis — domestic cloud

ez2AI-Core reads existing materials to understand relationships between data and screens, without an external connection.

Create code and documents — external AI

External AI is used only to create code and documents. It receives work instructions and results, and the model can be chosen.

Separated by company and team · on-premises option

Materials are stored separately by company, team, and user. For restricted environments, the service can run on your own servers.

Accredited test report KST-26-131 (ISO/IEC TS 4213:2022 6.2.4, issued 2026-08-04) · Cloud service confirmation KACI CSA-014-2026-03 (valid through 2027-03-23; registered service name: ez2AI Cloud).

What happens when you start from code

The difference between a structure that collapses as features are added and one that gets stronger.

	Vibe coding	Harness coding
Start	Code first. Generation with no design	Design first
What the AI knows	General knowledge	This business's structure, relations, and rules
Process	Throw a prompt, look at the result	Design → instruction synthesis → generation → review
Output	Code fragments	Design docs, tests, code, work log
Adding features	Collapses as it grows	Gets stronger as it grows
Months later	Nobody knows why it was built that way	The record is there, so the next person continues
Result	Prototype	A running system

That is why Harness Builder is different

Design, documents, code, and review all follow one shared standard.

One standard carries through to the end

Manage screens, data, and business rules in one design so documents and services move in the same direction.

Start with the way your company works

Apply your terminology, work rules, and templates first to produce results fitted to your organisation from the start.

Do not explain the same decisions to AI again

Confirmed designs and work records carry into the next task, so decisions do not need to be repeated.

Continue building an existing system

Read existing documents, screens, and data to understand the current structure, then continue design and development from where it stopped.

Review the result against the standards

Check the result against the design and company standards, with the needed revisions and their grounds.

Nothing is invented without grounds

When evidence is insufficient, it does not make up a plausible answer; it leaves the point for a person to confirm.

What to know before you start

No usage overages: The fee is monthly and usage does not add extra charges.
External AI cost: Individual plans (Lite, Solo) cover their own external AI cost. For business plans (Pro, Max), whether seats are included and whose name the account is in are settled in the quote.
You own the code and deliverables: All rights to the code and deliverables you create belong to you.
Consulting and server setup are separate: If needed, these are quoted separately at published rates.

Validate first, then scale

Start before you hire or outsource

Build something real before committing people or budget, then make your next decision with confidence.

01
Build first, then decide
See the screens and workflows you need before hiring a developer or commissioning an agency.
02
Start alone, scale with a team
When your team forms, simply move up a plan. Your accumulated designs and company knowledge move with you.
03
Let the next person continue immediately
Design documents, tests, and work records remain together, so a new owner does not have to start by asking again.

At first the AI asks a lot. It does not know your work yet.

From the second task it asks less. It remembers what you decided last time.

Use it long enough and it hardly asks. Like someone who has worked with you.

A tool that does everything for you is easiest on day one and disappoints from there. Harness Builder is the opposite.
