What is SOSEI?
SOSEI is an AI website rebuilder that turns an outdated site into a modern, standards-compliant one in about one to three minutes. You submit your website address and SOSEI runs a free 40-point audit in seconds — it only reads your public site — then generates a rebuild. Every rebuild ships with a defined baseline by default: WCAG 2.1 AA accessibility, a GDPR cookie-consent banner, a sitemap plus robots.txt and an llms.txt file for AI crawlers, self-hosted fonts, six generated legal pages, images rehosted rather than hotlinked, a contact form with inbox, and SSL and hosting included. It's tuned across 161 industries. SOSEI is a subscription service rather than a one-time build, positioned to keep the site current as Google and AI search change. If you don't have a site yet, it can also build one from scratch. According to the homepage, it has shipped 106 rebuilds and run 1,010 free audits, with an average site score improving from 83 to 94 before and after. The main caveat is that specific subscription prices aren't shown on the landing page, so you'll need the pricing page to see plan costs.
What is SOSEI used for?
Best for small businesses with an outdated website that want a modern, accessible, GDPR-compliant rebuild without hiring a developer.
