Private AI that works with your data
Artificial intelligence (AI) is no longer just a hope for the future – it has become an everyday tool that helps organizations manage information more efficiently, accelerate decision-making processes, and reduce manual routine work. However, applying AI to sensitive or business-critical documents raises questions about data security, compliance, and control.
The solution is private document-aware AI, which allows artificial intelligence to work with a company’s own files and knowledge without compromising data protection and privacy.
Who is private document-based AI suitable for?
All areas that deal with large volumes of documents, internal knowledge, and unstructured data will benefit from this technology:
Legal field
-
Comparison and analysis of contract texts
-
Responding based on case law, internal policies, and regulations
-
Responding to customer inquiries with the support of legal sources
Finance and audit
-
Interpretation of international standards (IFRS, GAAP)
-
Creating reports from multiple document sources
-
Accelerating audit preparations and preventing risks
Healthcare and pharmaceuticals
-
Drug information and research content analysis
-
Rapid response to internal treatment guidelines and procedures
-
Maintaining privacy when handling sensitive patient data
Industry and manufacturing
-
Reviewing safety manuals, maintenance logs and technical inspections
-
Resolving technical issues based on documentation
-
Internal knowledge retention and accessibility
Research and development
-
Analysis of research papers and scientific articles
-
Finding connections between topics in large blocks of data
-
Supporting working groups with content-based knowledge creation
How does document-based AI work?
The system relies on two key components:
-
Vector-based database (e.g. Qdrant), which allows documents to be searched and ranked semantically.
-
Language model (LLM – Large Language Model), which can generate meaningful, context-sensitive, and understandable responses.
A typical workflow via a third-party API (e.g. OpenAI) looks like this:
-
Company files (PDF, DOCX, emails, manuals, etc.) are uploaded to a securely isolated system.
-
The contents of the files are converted to vectors (for example, using
text-embedding-3-largemodel) and saved in the local vector bank. -
When a user asks a question, the system finds the most relevant passages from the documents.
-
These snippets are passed to a language model (e.g. GPT-4o) via an API to generate a response.
Does an API-based solution mean data leakage?
EiIf the system is configured correctly, the solution connected to the API is also secure. Why?
-
Only necessary text segments are transmitted, not the entire document or database.
-
OpenAI’s commercial customer data is not stored or used to train modelsif the appropriate privacy settings are set (e.g.
data_opt_out). -
The API connection is encrypted. (HTTPS/TLS), so the information is transmitted securely and is not readable by third parties.
- The company’s user interface is secured with user rights, passwords, brute force attack protection, a firewall, and, if necessary, 2FA authentication.
This approach is well suited for companies whose data is sensitive but who do not require complete locality.
What to do if a full inspection is necessary?
If an organization is required to meet strict information security standards (e.g. GDPR, ISO / IEC 27001) or if customer contracts or national requirements require full data localization, then it makes sense to implement completely private installation.
In this case:
-
The generation of embeddings and processing of the language model are carried out completely on a local server or in a closed European-based GPU cloud service.
-
No data chunks are sent outside the network.
-
Answers and inquiries remain completely within the company’s internal network.
-
It is possible to implement role-based access, logging, 2FA and workspace differentiation based on usage rights.
Summary
Document-based private AI is not just another technological gadget – it is strategic solution, which can use the organization’s existing knowledge quickly, appropriately and securely.
Companies that:
-
work with large databases and documentation on a daily basis,
-
want to speed up decision-making processes and reduce information searching,
-
need control over the movement and use of data,
can gain a significant competitive advantage with private AI. And while API-connected solutions are secure enough for most, the most demanding can opt for a local installation – completely without compromise.
