All your tools
Right where you work
The Vernelys platform on desktop and on mobile, and the Excel, Word and Outlook add-ins inside the Microsoft apps.
An AI platform shaped around your organisation and hosted in France, built to give your teams their time back. It opens on your computer and on your phone, and the Excel, Word and Outlook add-ins work inside the software you already use.
Your organisation's workspace
Assistant, meeting minutes, document agents working on your client files, and administration for your teams. On your computer and on your phone.

A ribbon tab and a side pane in the software you already open, for pulling data out of your PDFs, formatting, shortcuts and assisted drafting.
Explore the add-insEmployees bring AI into your organisation through their own tools, on accounts you never see.
Your employees work with the same models, inside a protected, sovereign framework.
Microsoft and LinkedIn, Work Trend Index 2024: 78% of people using AI at work bring their own tools.
Out of ten employees, eight send documents to their own AI tools, outside the organisation. Vernelys closes that perimeter: the same vendors and open-source models stay available, but through a single door, with processing in the European Union, no retention, no training and end-to-end encryption.
Stop stacking up subscriptions
Four tools means four subscriptions, four logins and four invoices. Vernelys brings them into a single workspace.
A single subscription
One workspace, one login, one invoice. Simpler, and more economical.

Every model on the market,
inside a professional setting
Your documents never leave your workspace. They are stored in France, processed in Europe, and they train no model. Web search stays optional, question by question.

We track the model market for you
New models are released every month. We evaluate them and update the platform, with nothing for you to do.






Continuous updates
When a model performs better on the work you actually do, we put it into service. Your settings and your habits stay exactly as they were.
Reviewed before going live
Every new model goes through a security and compliance review before it reaches your workspace.
Included in your subscription
New models arrive within your current subscription, with no module to buy and no price revision.
There is no contract to renegotiate and no migration to plan when one provider pulls ahead of another.
The shared foundation,
then the bespoke work
The platform and its modules form a shared foundation: every organisation using it runs on the same technical base and the same security rules. When one of your processes doesn't fit, we audit it and then build it, and the resulting component joins that shared foundation instead of living alongside it.
The audit, free of charge
We go through your processes with you to separate what the platform already covers from what needs building, and from what gains nothing by being automated. You leave with a written, costed scope, with no commitment.
The bespoke build
We build what you're missing and install it into the shared foundation, with the same account, the same permissions and the same separation of client files as the rest of the platform. From then on it follows updates like any other module.

Encrypted in transit and at rest
Queries and documents are encrypted while travelling and while stored on our systems. Access is restricted to authorised staff and is logged.
Built for professional codes of conduct
Designed with accounting and legal professionals to meet the requirements of their governing bodies and regulators: auditability, confidentiality, separation of client files.
No data used for training
Our contracts with model providers prohibit any use of your content for training.
