The confidential pro — « My files never leave my workstation. »

Lawyer, doctor, HR professional, consultant, CPA, notary—you handle documents covered by professional secrecy or an NDA. A local LLM paired with RAG lets you query, summarize, compare, and cross-check them without ever uploading anything. And without the command line.

Our promise

By the end, LM Studio will run with a polished graphical interface (no terminal). A 13–24B model will be loaded. A folder of PDFs will be indexed through AnythingLLM or the built-in Documents feature. You’ll be able to ask your archives questions in French, get exact citations with page numbers, and export a summary—without a single byte leaving your machine.

Who it's for this path is for you

We'd rather tell you early than let you waste 30 minutes for nothing.

✓ This is for you if
  • ✓Your documents are covered by professional confidentiality (lawyer, doctor, notary, certified public accountant).
  • ✓You work under an NDA, and cloud tools are contractually prohibited.
  • ✓You handle personal data subject to GDPR—avoiding transfers outside the EU is imperative.
  • ✓You want a clean, clear UI—not a command in a terminal.
  • ✓You have 100 to 10,000 PDFs to query without re-uploading them every time.
✕ Look elsewhere if
  • ·Your data is public and you just want an assistant: a cloud service will be simpler.
  • ·You manage terabytes of documents: you need a server deployment, not a workstation.
  • ·You want real-time processing on hundreds of documents per second: a simple RAG pipeline won't hold up; see vLLM or TGI.

Frequently asked questions

The real questions we get by email and on Mastodon. If yours is missing, open a ticket.

Yes, by design: no data is transmitted to a subcontractor. You remain solely responsible for processing. Just make sure disk encryption is enabled (BitLocker, FileVault, LUKS) and that you have a conversation-retention policy.
