PrivaSearch or Langdock?

Langdock is a German AI workspace in which your team can work with many models, including the latest. So the difference with PrivaSearch is not in the model, but in what the model gets to see and in what you still have to arrange yourself.

PrivaSearch

Your own client files, safely searchable from the AI assistant you already use.

€175 a month for the whole firm, up to 10 employees

Langdock

One workspace for chat, agents and many models from different suppliers.

€25 per user a month

Go to the Langdock website

In short

Three differences that matter.

  1. Both give you the latest models. With Langdock the document goes to the model as it is; with PrivaSearch only released passages with pseudonyms.
  2. Langdock is a workspace for everything. PrivaSearch is made for client files with personal data, with the AI policy, the DPIA and the AI training included.
  3. Langdock costs €25 per user a month. PrivaSearch costs one amount for the whole firm.

Side by side

Topic by topic.

What is said here about Langdock comes from that party's own website. The sources and the reference date are at the bottom.

Topic PrivaSearch Langdock
What the AI model gets to see Only passages in which names, addresses, numbers and other personal data have been replaced by pseudonyms, and only after a person has approved the privacy review. The link to the original stays in a vault and does not go along. The questions and documents your team enters, as they are. The site mentions no pseudonymisation beforehand.
The GDPR Designed for the GDPR: less data to the model, a mandatory review, a log of every action, plus the AI policy, the DPIA starter document and the entry for your record of processing activities. Langdock says on its site that it adheres to the GDPR. You arrange an AI policy, a DPIA and the training of employees yourself; a component for oversight is included until 1 January 2027 and costs extra per user after that.
Hosting EU-sovereign hosting: storage and processing with a European provider. The assistant you connect may be American; it only receives the pseudonymised passages. Hosted in the EU; also possible in your own cloud or on your own servers.
The models The latest model from Claude, ChatGPT Business or Mistral Vibe. You choose the assistant and the model; when a new model comes out, you simply use it. More than forty models, including recent models from OpenAI, Anthropic and Google.
What's included Search in your client files, the privacy review, the AI policy, the DPIA, the AI training for every employee, the audit log and the connection with your assistant. Chat, agents and an API; automated workflows at an extra charge per workspace.
The price €175 a month up to 10 employees, €350 up to 25. Per organisation, not per user; excl. VAT and the subscription to your assistant. €25 per user a month, excl. VAT. For 10 employees €250 a month, for 25 employees €625.

To be fair

Where Langdock is stronger.

  • The latest models from several suppliers in one workspace, without separate subscriptions.
  • Agents and automated workflows.
  • Can run in your own cloud or on your own servers.
  • A free seven-day trial.

And the other way round

When PrivaSearch is the better fit.

  • Your client files contain personal data that a model may not see unedited.
  • You want a person to release a document before it is searchable.
  • You do not want to draw up the paperwork for the GDPR and the AI Act yourself.
  • You do not want to pay per seat.

What's in PrivaSearch

Seven components, one subscription.

No separate packages and no extra charge per component. See the pricing.

  1. Search in your own client files Ask questions about your documents, with a reference to the source for every answer.
  2. Pseudonymise before the model Personal data is detected and replaced before any text goes to an AI model.
  3. Mandatory privacy review Nothing is searchable until a person has checked and released the document.
  4. AI policy, DPIA and record of processing activities Starter documents based on your own setup, for your lawyer or DPO to review.
  5. AI training for every employee The AI literacy from the AI Act, with an overview per person.
  6. Audit log and access management Every action recorded, with roles per project and mandatory two-step verification.
  7. Connection with your AI assistant Search from your assistant through MCP, within the same permissions and project boundaries.

The latest models

You work with the best model there is.

PrivaSearch supplies the passages; the thinking is done by the model you choose in your assistant. A platform that hosts open models itself works with smaller models that arrive later. A platform that chooses for you does not always choose the most powerful one.
