Local AI · your own hardware · human approval
Local AI for business on your own hardware
Start with a free fit check and a free demonstration using anonymised or approved sample documents. If the result is convincing, test one ready-to-use workflow for six weeks against agreed acceptance criteria before you decide on production.

The outcome
No technology project without a practical result
The local AI workspace is configured for one verifiable process. The paid practical test determines whether its quality, speed and usability meet the agreed acceptance criteria for your business.
Drafts instead of blind sending
The AI prepares summaries, emails or next steps. Binding statements and external actions remain with the responsible person.
Ownership and exit clarified
You own the production hardware and customer data. Agreed configurations, exports and operating documentation are handed over for transparent continued operation.
Processing on your premises
The AI works where your documents are stored
Under the agreed local operation, document processing and AI inference run on the customer system. External interfaces, remote maintenance, backups, telemetry and updates are not hidden: each is identified in a data-flow overview.
This makes “local” a verifiable technical configuration—not a blanket data protection promise.
Controlled workflow
- 1. Approved documents
Only agreed collections and roles are included. - 2. Local processing
The selected model runs on the configured hardware. - 3. Result with source location
The answer or draft remains verifiable by employees. - 4. Human approval
Binding and critical steps are not carried out autonomously.
Industry packages
One technical core, clearly defined workflows
We do not start with a generic chat window. We start with documents, roles and an outcome your team can genuinely verify in daily work.
Starter package
Construction and skilled trades
Quotes, measurements, site diaries, variations and correspondence become searchable within an approved collection. The AI can summarise content and prepare drafts; pricing, commitments and sending remain under human control.
- Document search with source references
- Project and case summaries
- Preparation of emails and variation notices
- German, English or Turkish after acceptance testing
Tax firms and confidential environments
Before using real client data, firms review which documents, access rights and participants are required. The practical test begins only after data protection, confidentiality and support rules have been agreed.
- Search assessments and written submissions with source locations
- Summaries of incoming client communications
- Deadline alerts solely for professional review
- No autonomous tax advice or posting
DATEV integrations and local archiving are not automatically included.
Prove it first, invest second
Four clear steps before production
1. Free fit check
We assess one workflow, suitable sample documents and measurable acceptance criteria without charge.
2. Free demonstration
We demonstrate the approach using anonymised or approved sample documents. Real data only follows within the agreed safeguards.
3. Paid six-week practical test
For €4,900 excluding VAT, up to five named users test quality, sources, speed, access rights and the approval process against the agreed acceptance criteria.
4. Production decision
Only after a successful test do you receive an acceptance report and decide whether to commission production setup.
Transparency instead of a seal
Local operation supports control—but does not replace governance
Compliance and data protection depend on the specific use, access rights, data flows and operation. HK-Build provides the technical and documentary elements of the agreed system, but no legal or tax advice.
Included in the agreed project
- Data-flow and interface overview
- Roles, access rights and remote-maintenance concept
- Technical and organisational measures for the system
- Input for the data processing agreement and the customer’s own record of processing activities
- Training, acceptance testing and a documented exit
Deliberately not promised
- No blanket “GDPR certification”
- No “data are guaranteed never to leave the premises” without a complete review
- No legal classification without a specific use case
- No autonomous professional decision or unchecked posting
- No DATEV or archiving function without a separate quote
Official guidance: Section 62a StBerG, the BfDI model for commissioned processing and the European Commission on the AI Act. Contract documents for tax firms should be reviewed by a qualified professional before production use.
Clear pricing structure
Practical test, production setup and operations are separate
Hardware and third-party licences are listed separately. This shows what you own and which ongoing service HK-Build actually provides.

Frequently asked questions
Local AI, clearly explained
What does local AI mean?
In this offer, local AI means that the agreed document processing and AI inference run on hardware at your premises. External connections, remote maintenance, backups and updates are identified separately and agreed in writing.
Do all data always stay within the business?
Under the agreed local operation, document content and AI inference remain on the customer system. An absolute statement is only possible once remote maintenance, telemetry, external interfaces and backup destinations have also been reviewed and configured accordingly.
How much does a dedicated AI workspace cost?
The Local AI fit check and demonstration using anonymised or approved sample documents are free. The six-week practical test costs €4,900 excluding VAT and uses agreed acceptance criteria. Production setup starts at €12,900 excluding VAT and is commissioned only after a successful test and your decision; the practical-test fee is then credited in full. Hardware, licences and special integrations are quoted separately.
Is a local model as capable as major cloud AI?
Not in every case. The model, hardware, concurrent users and document volume are therefore tested with typical cases. Before production, the practical test shows whether quality and speed meet the agreed acceptance criteria for the selected workflow.
What happens after cancellation?
Customer-owned hardware and data remain with the customer. Agreed configurations, workflow exports and operating documentation are handed over. Without a support agreement, monitoring, support and future updates cease; external licences remain subject to their respective terms.
Is a DATEV integration included?
No. A DATEV integration is not part of the practical test or the basic configuration. It can only be offered separately after technical, contractual and data protection review.

Does local AI fit your workflow?
Tell us your industry, document types and the one workflow that currently costs the most time. We will assess the fit for free and, if suitable, demonstrate the approach with anonymised or approved sample documents before you decide on a paid practical test.
