Adding AI to your website: what is useful and what is not

In short: artificial intelligence is useful on a website when it meets a precise need: answering frequent questions, helping people find a product, saving time on writing or sorting requests. It can be added to WordPress as well as PrestaShop, through a plugin or custom-built. Two rules not to forget: tell your visitors they are talking to an AI, which has been mandatory in Europe since 2 August 2026, and protect their data.

How an assistant works on a website

An AI model, the program that writes the answers, does not know your company. To answer correctly, your website sends it, with each question, the relevant passages of your own content: FAQ, product pages, terms of sale. The AI then writes an answer based on your information, not on guesswork.

A reliable assistant relies on your content, and tells visitors they are talking to an AI.

Three ways to add it

  • A ready-made plugin

    For WordPress or PrestaShop: quick to set up, but limited to what the plugin offers.

  • An online service connected to the site

    An assistant hosted by a provider: simple, but check where the data goes and what each exchange costs.

  • A custom integration

    A direct connection to a model, such as those from OpenAI, Anthropic or Mistral AI, the companies behind ChatGPT, Claude and Le Chat: more control over answers and data, at the cost of development work.

The rules to follow

  • Inform your visitors: since 2 August 2026, the European AI Act requires telling people they are interacting with an AI, unless it is obvious. A simple mention at the start of the conversation is enough.
  • Label generated content: an image or video created by AI that imitates reality must be presented as such.
  • Protect data: personal data rules apply, supervised by the CNIL in France and the APDP in Monaco. Only send what is necessary, and choose services that state where and how data is processed.
  • Own the answers: what your assistant says commits your company. In Canada, in 2024, an airline had to honour a refund promise wrongly made by its chatbot.

Mistakes to avoid

  • Adding an assistant without a precise need

    A gadget that answers badly does more harm than no assistant at all.

  • Letting it answer without limits

    An assistant must neither invent a price nor promise a timeframe: it sticks to your information.

  • Forgetting to inform visitors

    It has been an obligation in Europe since 2 August 2026, and it is a matter of trust.

  • Sending sensitive data

    Health information, payment details, confidential documents: they have no place in a conversation with an AI.

  • Forgetting the usage cost

    AI services are often billed by the amount of text processed: a spending cap avoids bad surprises.

  • Never proofreading

    What AI produces must be proofread, especially what is published on your website.

Where to start

  1. Pick a measurable need. For example: answering the ten questions you are asked most often.
  2. Test small. On part of the site, or with a small group of customers.
  3. Measure. Questions solved, time saved, requests handed over, sales.
  4. Expand if it works. And drop without regret whatever brings nothing.

The notice to display

A simple sentence, visible from the start of the conversation, is enough. For example:

You are chatting with an automated assistant based on artificial intelligence. Its answers may contain mistakes: for any important question, please contact us directly.

Have an AI project for your website?

I add AI to your WordPress or PrestaShop website when it meets a real need: an assistant fed by your content, a smarter search, writing help. And you talk directly to the person who writes the code.

Frequently asked questions

Does an AI assistant replace customer service?

No: it answers simple, frequent questions, and must know when to hand over to a person for the rest.

How much does using an AI cost?

AI services are often billed by usage, according to the amount of text processed. A spending cap avoids bad surprises.

Does my data leave the country?

It depends on the service chosen. Check where data is processed, and whether it is used to train models: options exist to limit these risks.

Can AI write all of my website’s content?

It can help, but fully automatic content, without proofreading or expertise, brings little to your visitors. Google favours useful content, however it is produced.

Do I have to inform visitors?

Yes. In Europe, since 2 August 2026, a person interacting with an AI must be informed of it, unless it is obvious.

How much does an integration cost?

It depends on the use and the method chosen. I never quote without looking first. Describe your project: I reply within one business day, with a free, clear, itemised quote.
