Thesr for Legal Publishers

Your collection, found in an instant. Even inside your readers’ AI.

A best-in-class legal search engine, a modern reader and a native connection to the AI assistants your subscribers already use. In your colours, on your infrastructure or ours, with security designed to protect your content.

Search

Search built for lawyers, not just a text box.

Your readers write queries the way they reason. The engine reads the full text of every document in its own language, recognises the forms of a word and ranks results consistently, highlighting the passages that answer.

  • Exact phrases — in quotes, in order, and nothing merely similar.
  • AND, OR, NOT — and their French equivalents ET, OU, SAUF, to build the most precise queries.
  • Forgiving — accents, case and word forms are ignored; a misspelt title is still found.
  • Filters — by collection, category and sub-category, and by period.
  • All your formats — PDF, Word, PowerPoint; scanned archives read by character recognition; two-thousand-page treatises read chapter by chapter.

AI assistants

Your content, where your subscribers already ask their questions.

Claude, ChatGPT, Copilot or Le Chat: your subscribers connect their assistant to your collection through MCP, the open standard for AI assistants. The assistant searches and reads your documents, and every result links back to your reader.

  • Your rights apply — an assistant only reaches what its subscriber may read: your subscription model applies inside the AI too.
  • Under your control — permitted capabilities, rate limits, revoking access: everything is configurable, every call is logged, and nothing can be deleted.
  • No training — Thesr never uses your content to train a model.

White label and integration

Your platform, in your colours, inside your systems.

In your colours

Your logo, your brand guidelines, your domain name: readers stay with you, from the first screen to the reader.

On your infrastructure

Deployed in your containers, on your private cloud or on your premises — or hosted by Thesr in France if you would rather not manage anything.

Connected to what you have

Your subscription management and billing stay yours: Thesr connects to them, and to your identity provider through single sign-on.

Security

Your collection is an asset. It is protected like one.

A collection is pillaged through repeated downloads and shared access. Thesr monitors usage continuously and acts before the damage is done.

  • THESR Guardian — detects mass downloads and unusual sign-ins, and can block an address, end a session or lock an account.
  • Controlled access — passwordless sign-in, two-factor authentication, single sign-on; one session per account, which discourages sharing access.
  • Isolated files — every document is opened in a sealed environment with no network; every customer is kept apart.
  • Rate limits — for readers and AI assistants alike, with every access logged.
  • In France — hosting in France with verified daily backups, or on the infrastructure of your choice.
