Claude & GPT: AI at work, not in a demo.

The two best AI models on the market, built in where they genuinely save time: chatbots, assistants, content, automations.

AI at Widesign

What we build with Claude & GPT

A general-purpose model answers everything, and misses the point. The value appears when the AI works on your content, your rules, your real cases. That is our job: defining what the AI reads, what it can do, and integrating it cleanly into your tools.

Why Claude & GPT

Why build with Claude & GPT

Reason 01
The right model for the right job
Writing, document analysis, customer dialogue, data extraction: each model has its strengths. We test on your real cases and choose on results, not on trends.
Reason 02
Your data under control
What the AI can read, do and say is defined in black and white before it goes live. The business access we use excludes training the models on your data.
Reason 03
Reversible integration
The architecture separates your business logic from the AI model: if a better model comes out tomorrow, we switch engines without rebuilding your integration.
Reason 04
Predictable costs
Usage is costed before going live: estimated volume, configured caps, alerts. You know the monthly cost before signing, not when the invoice arrives.
Reason 05
People stay in control
Human approval wherever it is sensitive, escalation at the slightest doubt, a complete activity log: AI speeds up your team, it does not decide for them.

Our clients come for a website that reflects who they are

They leave with a website or a tool designed for their line of work, and they keep the keys.

EFFI Engineering website

EFFI Engineering

The website had aged and no longer did justice to the company's work. We reworked the structure, rewrote the content page by page, and prepared the redirects so that no existing ranking was lost.

Full website redesign
Térinéo website

Térinéo

The project started from a blank page, with no website and no online presence. We built the shop from end to end: visual identity, product pages, checkout flow and secure payment.

An online shop launched from scratch
Kebchi Solidarity website

Kebchi Solidarity

On a donation platform, every extra step makes people give up. We tightened the journey so that a contribution can be completed in a few clicks, on a phone as well as on a computer.

Four à Pain Européen website

Four à Pain Européen

Real technical know-how with no shop window online. We built the entire website, presented each product range on its own page and used the vocabulary of professionals in the sector.

Beyond the website, the challenge was two sales funnels. We built them from end to end, then produced the visuals and video edits that feed them.

Let's talk about your project

AI built in within a strict framework

Useful AI proves itself on your own cases, not in a demo. We move forward in written steps, and the AI only accesses your tools after your approval.

Step 01

The discovery call

Together, in thirty minutes and with no commitment, we identify the tasks where AI would save time and those where it has no place. If the answer is no, we tell you.

Step 02

The AI's written scope

We write down what the AI will be able to read, do and answer, what goes to a human, the estimated usage costs and the fixed price. You sign on this precise document.

Step 03

The screens and sample answers

Before any code, you approve the assistant's screens and a set of questions with the expected answers. This test set then serves as the reference for judging the work.

Step 04

The prototype on your real cases

We test Claude and GPT on your real documents and your real questions, then integrate the chosen solution in stages. Each stage is shown to you before going further.

Step 05

Supervised go-live

The assistant goes live with cost caps, an activity log and handover to a human. We train your users to check and correct its answers.

Step 06

Monitoring the answers

We regularly review the conversations, correct answers that miss the mark and adjust the instructions. If a better-suited model comes out, the integration lets us switch engines.

They talk about their experience

What our clients remember: listening, deadlines met, and a result that reflects who they are.

Honest advice

Integrating AI without losing control

The known pitfalls, made-up answers, exposed data, come from integrations without a framework.

Ours is simple: an explicit data scope, behavioural limits, an activity log, and a person supervising. AI does the work, you stay in charge.

  1. 01
    Explicit sourcesthe AI states its limits instead of making things up.
  2. 02
    Minimal accessit reads what is necessary, nothing else.
  3. 03
    Traceabilityevery agent action is logged.
  4. 04
    Human escalationdoubts always come back to you.
We can hear you from here.

Your questions about Claude and GPT

It depends on the task: we test both on your documents and your questions, then keep the one that answers best, sometimes both. The integration is designed to switch models without rebuilding everything.

No. We use the vendors' business access, which excludes training on your data, and we set out in writing what the AI is allowed to consult.

Not within our framework. The assistant relies only on your content, admits when it does not know rather than making things up, and hands over to someone on your team as soon as a doubt arises.

The models are paid for by the volume of text processed. We estimate this volume during the scoping session, set caps and show you the spending tracker: the monthly bill holds no surprises.

A prototype tested on your real cases comes first, to check that the AI adds something. The full timeline is written during the scoping session, once the scope is agreed.

Yes, but without jargon: we show your users what the assistant does, how to spot a doubtful answer and how to correct it. That way they stay in control of the tool.
