AI Website Production

An AI site isa site built with AI and structured so that you can keep running it with AI after launch. It is not only built with AI. After launch, most of your SEO and content work can be carried out together with AI. The site you are reading right now is the proof.

¥1,000,000+ (excl. tax, standard package) SEO, AIO and speed included Astro / Next.js / Webflow Every page checked by a person At least 2–3 months Updates by email (Site Care Plan from ¥15,000/month)

What

What makes it different from an ordinary site?

An ordinary site is an asset that needs a person every time you want to update it. An AI site is built so that its structure, content and analytics are allin a form AI can read and edit. That is why, after launch, analysis, improvement and new pages all move with nothing more than an instruction to AI. More than the low build cost,this operating efficiency is the real product.

You Can

What AI operation lets you do after launch.

Every one of them is a method we use ourselves to build and run this site. Webharu carries out the work, andyou just send your updates by email. If you would rather run the site in your own AI environment, we can discuss handing it over.

Consult AI about your own site

“What is weak about this page?” “What should we add next?” — because the whole site is readable by AI, you always have a consultant that knows your site inside out.

Turn analytics into improvement plans

Let AI read your Search Console and GA4 numbers and produce concrete plans for which page to fix and how. No more staring at the figures and stopping there.

Rewrite every article in one pass

You no longer need to re-outsource slipping articles one at a time. AI reviews every article across the site and rewrites them together.

Have AI build the keyword strategy

Where and how to go after the keywords you target next. AI builds the strategy from your search data, and you can go straight on to writing the articles.

Adding and fixing pages is fast

Because the structure is AI-friendly, requests to add or fix pages turn around quickly and cheaply. You get out of paying tens of thousands of yen for a small change.

Get found by AI search as well

Structured data and llms.txt come as standard, so AI search such as ChatGPT can cite you easily. The design goes after traffic from AI search, not just Google.

* The Site Care Plan starts at¥15,000/month. Items 03 and 04 are for sites with a blog (CMS); to add a CMS or to keep articles running, combine this withArticle Production. Just let us know what you need.

Proof

The example is the site you are on right now.

webharu.com itself is an AI site. We used AI to build 26 pages, migrate 62 articles and set up the forms and the analytics stack, and we run post-launch analysis, rewrites and new pages with AI too. The whole build is published together with the real git history.

Roles

What the AI did. What the human did.

Saying “all of it was AI” would be a lie. Here is how the work was actually divided — and that division is exactly what decides the quality of AI-built work.

What the AI (Claude Code) handled

Generating design mockups as HTML (several options)
Coding every page (Astro, animations included)
Extracting, converting and migrating post and case-study data
Structured data, SEO settings, performance tuning
Investigating and fixing bugs, checking the rendering on real devices

What the human (Masato Kurita, Representative Director) handled

Deciding the concept and structure (what the site is there to say)
The aesthetic call on design — if that is where it falls short, we do it again
Fact-checking the copy, and the sales calls (pricing, how it is presented)
Reviewing each stage and giving the go-ahead

In short:the AI does the doing, the human does the deciding. Because a person who has kept writing Webflow guides and has been particular about design can concentrate purely on review, the speed of AI and the quality of a human hold together.
