Vernelys installs itself where
you already work
Up and running in minutes
Once installed, the “Excel Tools” tab appears the next time you open the app, without changing the way you work.
Employees 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.
The way you use Excel changes today
Dropped in, so carried along
A PDF dragged into the workbook is inside the .xlsx file. It lives and travels with the file.
The workbook leaves, its PDFs go with it
Send the file to whoever you like: it arrives whole. On opening, the “Preview” button finds the same documents. No more hyperlinks breaking on the first share.
Text, Sum, Table
The document appears beside the sheet, with nothing to download. Select what you need: a label, a column of figures or a whole table.
Collaborative, with review built in
Every extraction records who made it. The reviewer approves or rejects. Comments can be added freely to explain or add context.
The action you keep repeating,
on the keys of your choosing
The shortcut manager binds a key combination to a piece of formatting: fill, font colour, borders, cell format. You can create it, move it or delete it at any time; availability is checked live, including against Excel's own shortcuts.

Describe what you want, your assistant does it
A chatbot doesn't know my workbook.
This one read it before you spoke. The pane opens on the active sheet and on the range in front of you, with its columns, its values and its empty cells. You have nothing to describe to it before you ask for something.
An AI writing on its own into a production workbook, absolutely not.
You are the one who allows it. The shield in the input bar sets what the assistant is allowed to do. "Ask each time", the default, has it propose every write before making it; "Automatic", the setting used here, lets it write, and the ribbon's Undo button reverses everything. It writes formulas rather than pasted values, so the column stays live.
I can't write VBA, nor review the VBA someone writes for me.
You don't have to review it. In Developer mode, the assistant opens Module1 and writes the macro. Every line acts in front of you: the rules are drawn, the header turns green and the amounts take their unit. What you approve is the result, without having to go into the code.
Your templates in one shared library, inside Excel
They live on individual machines, each in its own corner. Vernelys brings them into a shared library, opened straight from Excel.
Templates and extraction models
Everyone's tools,
and yours on top
The audit, free of charge
We go through what you do in Excel with you: what the add-in already covers, what deserves building, and 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: the connection to your business systems, the automation of a process you redo every month, or a calculation rule specific to your work. The component installs into the add-in itself, and follows its updates like the rest of the tab.
Built for your organisation
Connected to your systems
The workbook pulls its data from your business software, and sends its results back.
Automations
The process you redo every month, in the same order, behind one button.
Bespoke processing
Your calculation rules and your checks, applied to the active sheet.

For accountants and auditors:
make your testing work less of a chore
You point to the year's VAT returns as PDFs. Vernelys reads them and writes one row per return: every box of the CA3 in its own column, ready to be reconciled against the accounts.
You import the batch of invoices to sample. Each one is read and poured into the same list: one row per invoice, with its data extracted and laid out as a table.
You point to the ledger and the invoices meant to support it. Vernelys sets each entry against its document: the amount read on the invoice, the variance if there is one, and the documents that are missing.
Sheet “VAT audit”: 6 rows written from 6 documents. Columns: Return, Net sales (01), Gross VAT (16), VAT on assets (19), VAT on other (20), Carried fwd (23), Credit (25), VAT due (28).

A chatbot doesn't know my document.
This one read it before you spoke. The pane opens on the active document, with its outline, its sections and the figures already quoted in it. You have nothing to describe to it, and no paragraph to copy into a browser window, before you ask for something.

"Ask each time", the default, has it propose every passage before writing it; "Automatic", the setting used here, lets it write, and Word's own undo takes back over.

Your templates and styles in one shared library, inside Word
A template gives you the right document to start from; a style set formats the one you have already written. Word saves both, on the machine that made them; Vernelys brings them together for the whole organisation.

Vos actions répétitives accessible en 1 clic
Résumer un fil, en traduire les échanges, améliorer un message, proposer une réponse : toutes ces actions sont déjà paramétrées pour vous.
Deux modules lancés, pas une phrase tapée.
Disponibles à tout moment
Les quatre actions s'affichent en cartes à l'ouverture du volet. Une fois la conversation lancée, elles restent dans le menu éclair de la barre de saisie, et un clic suffit pour les relancer.
Un clic, pas un prompt
Les quatre actions sont déjà rédigées et s'appliquent au message ouvert. Vous n'avez rien à taper, ni à copier votre courriel dans un autre outil : le résultat s'écrit dès le clic.
Le volet demande ce qui manque
Pour traduire, il faut connaître la langue d'arrivée ; pour répondre, savoir à qui. Le volet pose la question en un clic de plus, au lieu de choisir à votre place.
The email writes itself, you send it
Drafting a reply, shortening it, changing its tone, correcting what you have just typed: it all happens in the pane, on the open message.
It read the message before you did
The pane opens on the message in front of you: its subject, its sender, its attachments. You ask for a reply, and you don't have to recount the situation or copy a paragraph into a browser window.
The reply is written into the draft
It lands in Outlook's own reply window, not in a panel alongside. Nothing to copy and paste, and undo takes back over: what was put down comes out like any sentence you would have typed.
One line from you, and the send stays yours
Shorter, more formal, a deadline to add: one line is enough to have the draft reworked. What you type yourself is proofread, corrections shown word by word, and the message stays a draft until you click Send.

The answer is in your files. It arrives in the draft
For more context, query your document agents
From Outlook, without opening anything else: the pane reads the message in front of you and queries, at the same time, the document agents you have set up in the platform.
The cited documents, there to open
Every piece of information carries the source it came from, and the document opens in the pane.
Write the right prompt once, reuse it endlessly
Without the library

Written once, reused in two clicks, on any message.
The AI provider
is yours to choose
The engine that writes changes in one click, on the very next request if you like. Your commands don't move.
No provider imposed. OpenAI, Mistral, Claude, Gemini, Grok: you decide.
Nothing to reinstall. Switching engine takes no intervention, no configuration and no new habit to learn.
The catalogue follows the market. A model comes out, it joins the list: there is no migration for you to plan.
