An AI-powered website, turnkey

By Cédric Barme · Founder of NSY

An NSY website is not a dressed-up theme: it is a bespoke product, with AI integrated where it genuinely serves — assistant, search, content — and search optimisation designed for Google and for the AI assistants that now recommend providers. A turnkey offering, priced on your need.

What the package includes

• Bespoke design and build — a distinctive visual identity, no generic template; bilingual where your market justifies it.
• Useful AI integration — chatbot (LLM-based — Claude, OpenAI, Mistral — or a rule-based engine free to run, depending on the need), semantic search, controlled content generation.
• SEO + GEO optimisation — structured data, llms.txt, conversational FAQ: your site understandable and citable by Google as well as ChatGPT, Claude, Gemini or Perplexity.
• Performance and sobriety — short load times, controlled CPU/battery use, suitable hosting (Vercel, Cloudflare, Infomaniak).
• Go-live and evolution plan — deployment, handover training, 6- and 12-month roadmap.

The method, without surprises

Everything starts with the feasibility questionnaire: 7 guided steps that frame your project — goals, content, constraints, budget. Within 48 business hours you receive an honest read: what is feasible, the ballpark, and the next step. Then: mock-up, short iterations with regular demos, go-live. The person who designs the site is the one who delivers it — no subcontracting.

Proof over promises

The site you are reading is the demonstrator: bilingual, a chatbot with zero API cost, a resource-frugal real-time 3D model, complete structured data. On the client side, PRV Concept — an association showcase site with bespoke design, bilingual, forum and shop — is in production, and its twenty-year-old forum feeds the chatbot as a knowledge base: how an AI chatbot gets wired into a forum. The FAQ answers the budget, timeline and maintenance questions.

New build or redesign

The package described here starts from a blank page. If your site already exists, the work changes nature: earned search visibility has to be preserved, content and data carried over, redirects planned — that is the subject of the website redesign page. The feasibility questionnaire separates the two paths from its very first question and only shows what concerns you.

Who it is for

SMEs, mid-caps, associations and independents who want a site worthy of their business — and who prefer a single point of contact applying critical-systems standards (NSY has served banking and insurance since 2018) to an agency stacking layers. Three clients in parallel maximum — for real attention to every project.

NSY works across France, remotely — and on site when it helps. For example: website creation in Orléans (Centre-Val de Loire) or technical missions in Paris · La Défense.
