It's the sword of Damocles hanging over every German law firm: § 203 StGB (violation of private secrets). While the free market uses AI to become more productive, professionals often stand still out of fear. And rightly so. Anyone who carelessly uploads client data to the cloud risks not only a fine, but his license and imprisonment.
We're in 2025. The pressure on law firms and tax advisors is enormous.
On one hand: Shortage of skilled professionals. There are hardly any qualified tax assistants or legal assistants left. Files pile up, deadlines become a balancing act.
On the other hand: The data flood. Clients no longer deliver shoeboxes, but terabytes of digital receipts, emails, and chat histories.
The solution would be Artificial Intelligence. An AI that pre-formulates pleadings, comments on balance sheets, and summarizes files. But almost all leading AI solutions come from the US. And that's where the problem begins.
The Dilemma: Why "Standard-APA" Isn't Enough for You
Many US vendors wave a "Data Processing Agreement" (DPA) and claim to be GDPR-compliant. For a normal company, this might (with reservations) suffice. For you as a professional with confidentiality obligations (§ 203 StGB), it often isn't enough.
The law requires you to ensure that third parties ("assistants") don't gain unauthorized knowledge of the secrets.
A US cloud provider is subject to the CLOUD Act. US authorities can force access to data. If you load client data (e.g., in criminal law or sensitive M&A deals) into a cloud where a foreign intelligence agency could theoretically read along, you potentially violate your duty of confidentiality.
Even if the risk is minimal: Do you want to be the lawyer who sets the precedent?
The Solution: "Air-Gapped" Intelligence
At Syntriq, we developed TheroAI specifically for this scenario. We solve the problem not legally (through complex clauses) but physically.
The safest way to prevent data from flowing out is to never send it in the first place.
1. Local Inference (Local Inference)
TheroAI runs completely on your law firm's infrastructure. The AI's brain (the Large Language Model) runs in a Docker container on your own server.
When you ask a question ("Summarize this lawsuit"), the data never leaves your firm network. No API calls to California. No "training" in the cloud. The text is processed locally on your GPU and immediately forgotten.
2. No "Black Box"
As a lawyer, you need to know how a tool works. TheroAI is based on open technology. We can show you (and your IT audit) exactly where the data lives, who has access, and that there's no "phone home" mechanism.
Use Cases: Where TheroAI Does the Work in Your Firm
Once the legal hurdle is overcome through local installation, massive efficiency gains open up:
A. Mass Litigation (The "Diesel Scandal" Effect)
Law firms often drown in similar lawsuits. Thousands of pages of pleadings that differ only in details.
* TheroAI Use: The "Legal Agent" reads the opposing pleading (200-page PDF), compares it to your standard arguments, and immediately flags the opposing party's new, deviating arguments. You save 4 hours of reading time per file.
B. Due Diligence & M&A
In corporate acquisitions, data rooms with thousands of contracts need to be reviewed. "Change of Control" clauses must be found.
* TheroAI Use: You ask the AI: "List all contracts that contain special termination rights upon a change of ownership." The AI delivers an Excel table with references and linked clauses. Since this happens locally, sensitive deal data stays in-house.
C. Tax Classification (Mapping)
Tax advisors must map complex facts to current tax court rulings.
* TheroAI Use: You load the current tax authority guidance and commentaries into the knowledge database. Then you describe your client's situation. The AI checks the facts against current law (RAG technology) and provides an initial assessment with source attribution.
Conclusion: Technological Advantage Without Liability Risk
For a long time, lawyers and tax advisors had to watch other industries race ahead digitally. Security was the brake.
With TheroAI's local inference technology, we release that brake. You can now use high-end AI and still remain compliant with § 203 StGB.
It's time your law firm has time for what matters: advising your clients, not pushing papers.
