Why Butler exists

Sovereignty is the whole point.

AI has opened doors onto computing that were not open before: automation, and an ease with the machine that genuinely changes how work gets done. The problem lies elsewhere. Over the next few years AI will settle into every layer of companies infrastructure in Europe, and the overwhelming majority of that use rests, and will rest, on American and Chinese giants. That is where the question of sovereignty begins.

Because one of Europe’s great resources is the way it thinks. Our education, our research and our professional craft are among the most valuable things this continent has. And when you use an AI you do not only hand over what you are working on, you hand over how you work. Our way of resolving problems, of doing things leaves the continent, trains a model, and returns to us as a product: a loop of dependency, a digital colonisation of our education and our know-how. Extrapolated, we would not need that education any more, because the models have it for us. But since we do not control the models, and their price, we no longer control our own intelligence.

Hence the importance of keeping part of our work with AI under control: on a physical machine we own, that we can see and hear, standing close to us. It is a safety net first, the day access to the big models closes, or is repriced, part of the work stays here and stays ours. It is also the only serious way to handle sensitive data: the tool is encapsulated, and it is controlled. That is precisely why Butler exists, an AI toolbox under the desk that already does a good share of the job well, and with which you own a piece of your sovereignty and your freedom.

The compute is concentrated

A handful of companies control the hardware that frontier models are trained on. Everyone else rents access — at a price, and under conditions, they do not set.

One of Europe’s great resources is how it thinks

What leaves is not only your work — it is your method. It trains a model somewhere else, and comes back as a product you rent.

Nothing loops back out of Butler

Butler runs on hardware you control. Nobody knows what you do with it, and not one byte of it is fed back to train a model — not ours, not anyone’s.

One tool instead of five subscriptions

Chat, meetings, translation, research, documents — in one place, on one machine, for one price. No stack of per-seat American SaaS.

That is the whole idea: keep the work, the data and the know-how where they were produced.

The problem

Powerful AI shouldn’t cost you your data.

Every document uploaded to a cloud AI service leaves your control. Butler Suite is built for teams that can’t compromise.

Data leaves your control

Proprietary research, client records and strategy documents end up on someone else’s servers — outside your jurisdiction.

Compliance is a minefield

GDPR, medical confidentiality, attorney–client privilege: cloud AI makes every upload a legal question.

Dependency by design

Subscription prices rise, APIs change, services shut down. Workflows built on external systems are hostages.

Knowledge evaporates

Meetings, decisions and expertise disappear into inboxes and heads. Nothing is searchable, nothing compounds.

The tools

What is actually in it

Everything Butler does, grouped by the work. Each one is a real tool your team opens and uses — not a line on a feature list.

Writing & language

4 tools

  • Chat A conversation with an assistant, with your own documents and the live web available to it.
    Chat
  • Translator Side-by-side translation of text or a whole PDF.
    Translator
  • Proofreader A review pass over a document that returns suggestions you accept or dismiss one at a time.
    Proofreader
  • Butler Studio A collaborative document editor, with the assistant right inside the interface.
    Butler Studio

Your documents & what Butler makes of them

5 tools

  • Deep Research A question in, a structured and fully sourced report out — Butler plans the subtopics, searches, reads the sources and writes.
    Deep Research
  • Scholar Review An AI review of a PDF — paper, thesis or report — where every remark is anchored to the exact spot in the document.
    Scholar Review
  • Knowledge bases Your own document libraries. Butler indexes them so answers cite your files instead of guessing.
    Knowledge bases
  • Web Vacuum Crawls a website and stores its pages locally, in one of your knowledge bases.
    Web Vacuum
  • Assistant Training Build your own chat assistant: give it a role and connect it to your knowledge bases.
    Assistant Training

Meetings & records

3 tools

  • Meeting transcription Turns speech into a written transcript, then into a report you can edit and export.
    Meeting transcription
  • Meeting Report Templates Manage a set of templates that control what goes into a meeting report and how it reads.
    Meeting Report Templates
  • Speaker Dictionaries Teach Butler the voices of your group so transcripts carry real names instead of “Speaker 1”.
    Speaker Dictionaries

Making things

4 tools

  • Presentation Creator Turns a paper, a thesis or a report into a compiled LaTeX Beamer deck — figures placed, slides written, PDF built.
    Presentation Creator
  • Animation Studio Make your own animations: Butler writes a scene with Manim — the library behind the 3Blue1Brown videos — renders it and hands you the video.
    Animation Studio
  • PDF Handling Six utilities for working with PDFs.
    PDF Handling
  • Excalidraw Boards A flipchart for sketches, diagrams and visual notes, saved as boards.

Capabilities

One secure workspace. Every AI capability your team needs.

Your hardware, your model

A local GPU server runs open large language models with continuous batching — dozens of parallel users, zero external calls.

Air-gapped by default

Butler runs inside your network. Reachable from any browser on it, invisible from the outside.

Built for teams

Accounts, roles, two-factor authentication, shared folders and usage analytics — enterprise plumbing included.

Knowledge that compounds

Transcripts, documents and notes become a private, searchable knowledge base your AI can actually use.

How it works

Running in three steps

1

It arrives ready

A compact GPU appliance, preconfigured. Plug it into your network and it is running the same afternoon.

2

Your team opens a browser

Butler opens in a browser, in the building or from anywhere over its own VPN. Documents, knowledge bases and meeting reports are shared inside the team.

3

Work flows in, nothing flows out

Meetings, documents and chats are processed on the Butler itself. Your existing tools can use it where they are, through its API.

Who it’s for

For organizations where confidentiality is not a feature request.

Research institutions

Protect unpublished results and grant-sensitive data while giving every group modern AI tooling.

Medical & legal practices

Patient records and case files processed under confidentiality obligations — on premises, provably.

Finance & public sector

Regulatory filings and citizen data handled inside your perimeter, with audit logging built in.
