The site that rewrites itself for every visitor

Modular sites that use Vercel Edge Middleware and AI to adapt their copy, images and benefits in real time based on who's visiting — industry, role, region — without slowing the page down.

One site, a different experience for each visitor

When a Finance manager lands on the homepage, the message, examples and benefits are automatically rewritten (by AI) in their language; when someone from Healthcare arrives, the page instantly reconfigures for the medical niche.

It all happens at the edge, before the page loads — so it's fast, not a flickering client-side script. It's the technology enterprises pay top dollar for, delivered modularly and affordably by Websem.

What you get

  • Edge segment detection

    From available signals (geo, campaign/UTM source, referrer, optional firmographic enrichment on company IP), without slowing the page.

  • Modular, AI-rewritten content

    Headline, subhead, benefit and CTA variants per segment (industry, role, company size), with a safe fallback to the default.

  • Niche images & proof

    Visuals, client logos and case studies that swap based on the detected industry.

  • A/B testing & editorial control

    Libraries of variants you approve; the AI assembles, but never publishes anything 'wild'.

  • Per-segment measurement

    Conversion rate by industry/role, so you see exactly what works and for whom.

  • Modular = scalable

    Add a new segment (another industry) without rebuilding the site.

Reference claim: up to +40% conversion. Estimate based on industry benchmarks for personalized experiences; not (yet) a result measured by Websem. Replaced with the real figure after the first pilot.

How it works

  1. 01

    Detect

    The segment at the edge, in milliseconds, from available signals (geo, campaign, referrer, optional firmographic).

  2. 02

    Assemble

    The page variant from approved modules — AI-rewritten copy in the segment's language, plus niche images and proof.

  3. 03

    Measure

    Conversion per segment, continuously optimizing the variant library.

  4. 04

    Scale

    Add new segments through configuration, not by rebuilding the site.

Typical stack

  • Next.js 15
  • Vercel Edge Middleware
  • Edge Config / KV
  • Vercel AI SDK
  • firmographic enrichment (reverse-IP B2B)
  • GA4 (per-segment attribution)

Differentiators

  • Personalization at the edge, before render — no client-side flicker.
  • Editorial control: the AI works only from client-approved variants — no off-brand messaging.
  • Modular: a new segment = configuration, not a rebuild.
  • Privacy-first: based on context signals, no personal data in URLs or invasive profiling.

Proof · Pilot

Start with a homepage pilot

We don't have a public case yet — and we won't invent one. We start with a pilot on your homepage (2–3 segments) and A/B measurement. Once there's a real result, it becomes a showcase.

Frequently asked questions

Întrebări frecvente

Won't it slow my site down?

No. Personalization happens at the edge (Vercel Middleware), before the page is served, so there's no flicker and speed stays in the green.

Does the AI write on my site on its own?

Not unsupervised. It works only from variants you approve; you keep editorial and brand control.

What visitor data do you use?

Context signals (region, campaign, referrer and, optionally, firmographic on company IP). No personal data in URLs and no invasive profiling — GDPR-compliant.

Can I start small?

Yes: a homepage pilot with 2–3 segments and A/B measurement, then we expand.

Does it work over my current site?

If it's on Next.js/Vercel, yes, as an add-on. Otherwise, we build/migrate it.

Want a site that adapts to each client?

Request a personalization pilot — 30 minutes, free. We pick 2–3 segments and A/B test the real impact.
