🎥 Webinar on 27 October: ChatGPT is back, every new feature tested live

Why Claude is replacing ChatGPT in companies - Les Echos op-ed by Emma Pariente

Emma Pariente

This morning, the op-ed by Emma Pariente, CEO & co-founder of AI Sisters, went live in Les Echos.

Here is what prompted her to write it - because it is not only what you might think.

‍

The ethical trigger: yes, but it is not the main point

‍

Yes, there was the ethical trigger. OpenAI signing with the US Department of Defense.
Anthropic refusing.
Thousands of cancelled subscriptions in a week.

It is real and it matters, but reducing the switch to Claude to that alone would miss the main point.

The real question is not ethical.
It is practical.
Why are thousands of professionals trying Claude and not going back?

‍

The real reason for the switch: what we see in the field
‍

At AI Sisters, we train teams in large corporations: finance, legal, communications, HR.
‍The switch happens live, session after session.

What changes with Claude is not a feature, it is a level of rigour.
‍Claude does not just answer, it goes beyond the request, it spots inconsistencies, cross-checks information and anticipates what you have not yet put into words!

In practice, here is what AI Sisters clients see in our sessions:

A 200-page report becomes a usable analysis in a few minutes
A complex contract with several appendices: Claude keeps track of the whole document, not just the last question
A heavy Excel file: it processes it in full without breaking down, where ChatGPT loses the context

It feels like having an extremely intelligent, very reliable assistant that truly understands the standard required - and above all, one that delivers.

What Claude makes possible that others do not yet
‍

Beyond the quality of its answers, the Claude ecosystem has grown considerably.
The features that make the difference for companies today:

Artifacts - generates ready-to-use deliverables with no copying and pasting
Skills - persistent instructions that adapt Claude to your business context
Projects - long-term context memory, essential for long projects
Cowork - team collaboration in a shared Claude space
Dispatch - orchestration of complex multi-step tasks

These features considerably extend what can be done with AI today, particularly for demanding professional uses.

What this changes for companies that train their teams

‍

The switch to Claude raises a practical question for HR directors and other executives: do teams already trained on ChatGPT need retraining?

The short answer: you do not necessarily need to start again from scratch, but yes, the change needs support.

Prompts that work on ChatGPT do not give the same results on Claude.
The way you interact is different. Teams that learn to use Claude properly now gain a significant head start. Corporate Claude training is designed precisely to support this change.

This is exactly what AI Sisters does in its role-based AI workshops: adapting the training to the tool your teams actually use: ChatGPT, Claude, Copilot or all three!

‍

Question

Is Claude really better than ChatGPT for professional use?

On high-stakes tasks - analysing long documents, writing complex deliverables, keeping track of context - Claude regularly outperforms ChatGPT in tests carried out with AI Sisters clients. ChatGPT remains very strong on creativity and speed of execution for short tasks.

Question

Do you have to choose between Claude and ChatGPT?

No. Both tools have their place in a well-designed AI ecosystem. The AI Sisters recommendation: Claude for analysis, long-form writing and complex projects - ChatGPT for quick brainstorming and creativity. Copilot if you work in a Microsoft 365 environment.

Question

How do you train your teams on Claude specifically?

That is exactly what AI Sisters does in its workshops. Each session is built around the tools your teams actually use, with use cases adapted to your business and your processes. No generic training - tailor-made, in person.

How can I train my teams in AI without it taking months?

It is the question we hear most often. The short answer: with the right method, a single day is enough for your teams to really start changing their habits. At AI Sisters, we have built a three-step approach, tested on more than 350 projects:

Step 1 - Understand, not just "discover"
We start with an AI Show: a live, immersive session with real-time demos on real cases. No generic slides. Your teams leave with a clear view of what AI can (and cannot) do for them.

Step 2 - Practise on real topics
Hands-on workshops are organised by role: HR, Finance, Marketing, Sales, Legal, Ops. We use your real documents, your real emails, your real tools. Prompts are tested live.

Step 3 - Embed new habits at D+30
One month later, we run an impact review: what has been adopted, what is still blocking, what needs adjusting. This follow-up is what makes the difference.

In short: training your teams in AI does not take months. With an approach built on immersion, role-based practice and impact follow-up,

Can AI training really be adapted to my sector (healthcare, finance, industry...)?

Yes, and that is exactly what separates useful training from training people forget.

Before each project, AI Sisters carries out a pre-audit: we analyse your typical documents (contracts, emails, reporting, product sheets), your tools (Office suite, Google, CRM, ERP) and your workflows.
We identify where AI can create value in your specific context. Then we choose, from our 40 business experts, the one who knows your sector best.
An HR team in an industrial group will not see the same examples as a B2C sales team. Prompts, exercises, use cases - everything is adapted.

‍In short: AI Sisters adapts each training programme to the reality of your sector, thanks to a pre-audit and 40 business experts. Healthcare, finance, industry, services: content is built on your real documents and your real constraints, not on generic examples.

Can AI training be funded by my OPCO?

Yes, in most cases.
AI Sisters training is Qualiopi-certified, which makes it eligible for OPCO funding (French training funds). The level of funding depends on your skills operator, the scheme used and your available budget, but in many cases a significant part of the cost can be covered.

In practice, we support you through the whole application: detailed quote, compliant programme, supporting documents, follow-up until reimbursement.

‍In short: thanks to Qualiopi certification, AI Sisters training is OPCO-fundable. The amount varies with your operator and your situation, but it can mean substantial savings.

Is AI training better on-site or remote?

Both work. What matters is the intention behind the format.
‍
On-site is ideal for a strong kick-off: a seminar day, a moment of collective co-creation, a team starting out together.

Remote is perfect for multi-site or international teams - our online sessions use training assistants via chat to keep things interactive (Q&A, co-writing prompts, live exercises).

Either way, the method stays the same: AI upskilling + practice + follow-up. And every session is led by a business expert, not a generalist trainer.

‍In short: on-site or remote, the format adapts to your organisation. AI Sisters keeps the same level of quality and interactivity in both cases, with business experts dedicated to each session.

Which tasks can I really hand over to AI in my team today?

The best way to answer is by role.

‍HR: screen CVs, generate job descriptions, write emails to candidates, prepare interviews.
‍Finance: explain an Excel table, write a commentary on results, prepare a forecast budget.
‍Marketing / Comms: create an editorial calendar, adapt a message into several formats, A/B test hooks.
‍Sales: write prospecting emails, personalise sequences, prepare responses to tenders.
‍Legal: analyse an NDA, flag risky clauses, generate a first draft to review.
‍Leadership: summarise committee meetings, prepare strategy notes, build impact scenarios.

In our AI workshops, we do not show fictional cases. We take your real documents and test AI on them, live.

Before AI: 2 hours to write meeting minutes.
With AI: 20 minutes.
‍
Before AI: 3 hours to analyse an Excel file.
With AI: 30 minutes.

‍In short: AI can speed up dozens of practical tasks in every department. AI Sisters helps you identify the ones with the most impact for your team, and test them straight away on your own documents.

My team is not technical. Can they still use AI?

Yes. In fact, that is the whole point.

Our approach is 100% role-based, with no technical jargon. We start from your teams' real problems (lost time, repetitive tasks, heavy reporting) and show how to turn them into simple prompts.

At the end of the workshop, each participant leaves with ready-to-use prompt templates adapted to their job.

The goal is not to train data scientists. It is for every employee to be able to say: "This is how AI helps me in a typical day."

‍In short: You do not need technical skills to use AI every day. AI Sisters turns the tools into accessible, role-based practices, and gives every participant prompts they can use the very next day.

How can I be sure AI does not make mistakes in a sensitive context (legal, medical, financial)?

It is a more than legitimate question, and we address it directly in our training.
We do not just show what AI can do. We also stress what should not be delegated to it, how to review and validate its answers, and how to combine a clear business brief with a well-built prompt to get the best quality.

Our experts know the constraints of your sector: compliance, deadlines, accuracy, GDPR, approved tools.
Nothing is left to improvisation.

‍In short: AI Sisters builds the limits and risks of AI into its training. Your teams learn to use AI reliably, knowing what they can hand over to it and how to check the results.
