Much more than an AI website builder — this is a complete website visibility system!
What really impressed me about SOSEI is how much it brings together in one system.
A lot of website tools focus on just one thing — SEO, performance, design, accessibility or AI website generation. SOSEI approaches the website as a whole system.
It starts with a 40-point website audit covering design, mobile experience, SEO, AI discoverability, accessibility, GDPR/privacy, performance and more. But the really useful part is that the audit doesn't just produce a score — it turns the findings into a prioritized action plan, explaining what needs attention, why it matters, how to fix it, and the expected impact versus effort.
The AI visibility functionality is particularly interesting. SOSEI checks what ChatGPT, Claude and Gemini say when potential customers ask questions about a business, measures how often the business is mentioned, and shows which competitors are being recommended instead. That's a very different metric from traditional Google rankings and, in my opinion, one of the most forward-looking parts of the platform.
It also lets you benchmark your website against up to three competitors using the same 40-point audit, so you can see where you are actually ahead or falling behind across SEO, AI discoverability, accessibility, GDPR, mobile, performance and design.
Then it goes one step further: SOSEI can rebuild the existing website, rather than simply telling you what's wrong with it. It crawls the important pages, preserves useful content and images, keeps the brand recognizable, and creates a modern multi-page experience. The layouts aren't simply dropped into one generic template — the system adapts the design to the business, industry, brand and existing content.
From a technical perspective, there is a lot going on under the hood:
• SEO + semantic structure
• Google search visibility
• AI / GEO / AEO optimization
• Structured data / schema
• AI-crawler compatibility
• sitemap.xml, robots.txt and llms.txt
• mobile-first implementation
• WCAG 2.1 AA accessibility
• GDPR cookie consent
• self-hosted fonts
• SSL and hosting
• automatically generated legal pages
• server-rendered pages
• contact form and inbox
• daily backups with one-click restore
• before/after website comparison
• chat-based editing and regeneration
I also really like the idea of treating a website as something that needs to stay current, rather than something you redesign once every few years and forget about. SOSEI keeps monitoring AI visibility, provides ongoing recommendations and allows the site to be rebuilt against current standards as search, AI, accessibility and privacy requirements evolve.
That's ultimately what makes this interesting to me: it's not just an audit, and it's not just an AI website generator.
It's much closer to a complete cycle:
Analyze → understand → prioritize → fix → rebuild → measure → keep improving.
And the free audit makes it very easy to see where a website currently stands before committing to anything.
This is one of the more comprehensive approaches to website health and visibility I've come across.
Definitely worth checking out if you manage a website, work in SEO, run an agency, or simply want to know whether your website is actually visible in the AI era.
