Your firm has its knowledge. thesr gives it its library.

You have already done it. thesr knows.

No more digging to find your work on questions already dealt with. thesr brings together your memoranda, opinions, research notes, legal sources, deeds and digital books, and lets you use them like a legal database.

For Law firms In-house legal departments Notary offices Universities
Our vision

Your work is not ephemeral.

thesr keeps its value by giving it structure, speed and continuity. No more endless searching, lost history and opaque drives: welcome a clear, fast, shared legal memory.

Without thesr
  • Time-consuming searches hours lost in disorganised drives and unfiled folders.
  • Knowledge lost when a colleague leaves work, research, analyses and deeds stay on individual computers, wiped when they leave.
  • Reinventing the wheel on every file because it is neither structured nor used, the firm's knowledge forces you to start from scratch on work already done.
  • Confidentiality that is hard to control access rights that differ from one tool to the next, hard to control end to end.
With thesr
  • Immediate results a search interface comparable to a legal database.
  • A lasting institutional memory knowledge that stays with the organisation, regardless of departures and turnover.
  • Immediate capitalisation your work, reasoning, sources and wording can be used for every new request.

How does it work?

  1. Drop into thesr your consultations, memos, deeds, sources, e-mails, analyses and digital legal sources.

    Drag and drop, or synchronisation from your connected document management systems and drives.

    thesr reads, files and indexes your documents.

  2. Search your library as you would a classic legal database, or call on your connected AI assistant:

    • with the syntax of legal databases: quotation marks, AND, OR, NOT; or
    • through Claude, ChatGPT or Copilot - in your library only, within the permissions you have set

  3. Create a dedicated workspace for each of your cases, personal or shared with another member of your team, bringing together everything you need:

    • the relevant documents;
    • the legal sources;
    • your notes and drafts;
    • your tasks.
    Learn more

    Create it yourself or through your connected AI assistant (folder structure, adding all the relevant legal sources from your thesr space for the case in question):

    • Pleading files — documents and sources gathered in one place, easy to reach.
    • Targeted search — a scope limited to what is relevant to your issue.
    • Quick notes — notes written from the workspace’s sources.
    • Task tracking — useful as soon as several people work on the case.

  4. It is the engine room of your cases (in Workspace).

    Drop a case’s documents into a thesr workspace and launch Resolve, or simply ask your AI assistant to do it for you.

    When Resolve is launched, your AI assistant (Claude, ChatGPT, Copilot, Mistral…) reads them and builds for you:

    • the chronology of the facts,
    • the file of legal sources and/or previous work relevant to the case documents,
    • an analysis by theme,
    • the next steps, and
    • the research still to be done.
    Learn more

    Resolve leaves you in charge, and every item can be checked:

    • every item points to its source, document and page; whatever rests on no document is shown as an AI suggestion, to be checked;
    • you decide. Nothing is kept without you. What you have validated is never rewritten, and nothing is deleted.
    • thesr keeps the documents, the access rights and the history. The assistant you have chosen reads only what your rights allow, and each of its actions is logged.

    Resolve works whatever the nature of your case: litigation, a transaction, due diligence, an advisory matter, an insurance claim, and so on.

Connectors

Secure connectors to all your tools.

thesr Sync

Connect thesr to your storage. Your documents are filed by category, indexed and synchronised.

SharePointOneDriveGoogle Drive

  • Only the folders you choose are synchronised, read-only.
  • Without modifying, moving or deleting your files.
  • A local folder simply watched, or kept identical: you choose.

AI assistants

thesr is available to your AI assistants through an MCP server.

thesr does not impose any AI assistant: use the one you prefer, straight from its own interface:

CopilotClaudeChatGPT

  • Search and cite your sources
  • Build workspaces
  • Write notes
  • File your documents
  • Import from your drives
  • Keep your to-dos

Your administrators decide what an assistant may do, within each user’s own permissions (nothing can be deleted, every action is logged, everything can be revoked).

Security

A sovereign, secure platform, hosted in France.

thesr was designed for sensitive documents: segmented access, controlled hosting, strong authentication and advanced options for demanding environments.

French company Hosting in France Built-in anonymisation engine On-premise option

Fine-grained access control

Decide at any time who views, edits or downloads, at the level of the user, the team or the firm.

Infrastructure for sensitive environments

Flows stay under control: no content goes to a third-party service unless you have decided so. thesr Guardian monitors the infrastructure continuously and checks the integrity of its log.

Strong authentication

Magic link, 2FA, SSO, device management and access logging.

Strictly confidential content

A built-in anonymisation engine processes your most sensitive documents: identifying information is replaced and the original file is not kept.

Use cases

Many uses, one promise.

Find quickly, use effectively and durably secure your documentary knowledge.

Law firms

Build on your past work, save time on the next.

In a law firm, knowledge is everywhere and nowhere: in the pleadings of an old case, the memo of a colleague who has left, a decision downloaded three times, a template nobody can find. thesr brings it together in one shared library, organised by subject and fully searchable, where everyone finds in seconds the sources, the written work and the experience the firm has built up.

Each case can have its own dedicated Workspace. The documents are gathered there, the research is done in the firm’s library, and the notes are written next to their sources.

The firm no longer starts from scratch, the juniors benefit from the work of the seniors, and the knowledge stays with the firm when teams change, on a secure platform that keeps your data under your control.

In-house legal departments

You paid for this knowledge. Use it.

Every day, your teams ask lawyers about questions that others in your organisation have already had settled. The opinions pile up in mailboxes and closed files, without ever being used twice.

thesr turns every opinion received into shared knowledge. You brief your counsel on precise questions, building on what you already know: fewer billed hours, faster answers, expertise that stays with you.

Universities and business and engineering schools

A shared memory for your institution.

Lectures, research papers, dissertations, theses, case comments: the knowledge produced each year scatters as cohorts pass. What was produced one year is rarely found the next.

With thesr, the work of teachers, researchers and students is centralised, filed and accessible in seconds, on a platform that guarantees the sovereignty of your data.

thesr is published by a French company and hosted in France. Access is segmented by user, team and library, authentication is strengthened (magic link, 2FA, SSO) and every action is logged. For the most sensitive documents, a built-in anonymisation engine replaces identifying information and does not keep the original file.

Yes. The plans let you start simply, then add collaboration, governance, stronger security and capacity as you go.

We start from how you work, your volumes and your confidentiality requirements, and show you a credible scenario rather than a generic demo.
