01 — Legal AI assistant
The assistant that takes the initiative.
Wired into your firm's data, it doesn't wait to be asked. Your emails, your documents, your deadlines are what trigger it: it grasps the context, proposes a plan of actions, and acts only with your approval.
- a.Proactive, not reactive — it works from what comes into the firm to anticipate the actions, instead of waiting for a query.
- b.It proposes, you approve — a plan of actions before anything is written. Nothing runs without your go-ahead.
- c.Sourced answers — Légifrance · JudiLibre · BOFIP · EUR-Lex, every statement verifiable in one click.
02 — Cases & documents
Every document becomes usable data.
Drop in a document: it's read, classified and structured. Parties, dates, amounts and clauses are extracted — then made available to the assistant and the AI tools.
- a.Smart ingestion — entity extraction, automatic filing to the right case.
- b.Structured data — parties, dates, amounts, clauses: searchable, never again buried in a PDF.
- c.At the AI's service — everything extracted feeds the assistant and the analyses, no re-keying.

03 — AI tools
Your analysis methods, industrialised.
Beyond the chat: tools that apply your grids and playbooks to an entire portfolio of documents, and produce a sourced memo.
- a.Analysis grid — the same criteria extracted across every document, compared in a table.
- b.Playbooks — your recurring methods, saved once, replayed in one click.
- c.Sourced memo — issue → state of the law → application to the facts, citations included.
04 — Word & Microsoft 365
Your tools, augmented — not replaced.
Themis fits in where you already work: Word, Outlook, your calendar. Drafting is assisted, templates pre-fill themselves, mail and appointments stay in sync.
- a.Assisted drafting — suggestions and checks without leaving the document.
- b.Smart templates — your boilerplate pre-filled from the case data.
- c.Outlook & calendar in sync — emails attached to cases, hearings aligned.

Confidentiality
Themis vs consumer AI tools.
A consumer assistant is not designed for legal matters. The differences are not cosmetic — they engage your professional liability.

|---|---|---|
| Professional secrecy | Built for itGDPR processor under contract · ISO 27001-certified infrastructure | Not guaranteedgeneric terms, not enforceable |
| Hosting | European UnionAI processing in EU regions | Variesoften outside the EU |

Comparison based on the public terms of service of the main consumer assistants.
Sovereignty architecture
Your data is hosted and processed in the European Union.
Data travels a short, encrypted and auditable path through Themis — from document upload to the assistant's answer.

Contractual guarantees
Never a consumer API
Only contracted enterprise infrastructure, in European regions — no transfer to services intended for the general public.

The model provider retains neither your queries nor your documents: retention is disabled contractually and technically.
No training data
Nothing that passes through Themis feeds the training of any model — neither ours nor a third party's.

Security & confidentiality
The questions you must ask us.
Is my data used to train AI models? +
No, never. Neither your documents, nor your queries, nor your conversations with the assistant are used to train any model — ours or our providers'. This guarantee is contractual and architectural: we exclusively use enterprise AI offerings where training on customer data is disabled.
Where is my data hosted? +
In the European Union, without exception. The database, document storage and AI model inference all run in European regions subject to the GDPR. The list of our sub-processors and our impact assessments (DPIA) are available on request.
How is professional secrecy guaranteed? +
As a contractually-bound GDPR processor: your documents are encrypted in transit and at rest on ISO 27001-certified infrastructure, access is logged, and rights are finely managed per role within the firm. Zero retention on the model provider's side guarantees that no copy of your documents survives processing.
