BunkerM
On-premise AI assistant that lets your staff query plant equipment and company documents in natural language, with inference and storage staying inside your
If your problem is confidential documents leaking into ChatGPT rather than a lack of AI ambition, BunkerAI attacks the right layer — the retrieval and inference stack sitting in your own rack. The details that matter are permission-aware retrieval that respects existing document access rights, source-cited answers pointing to document and page, and human approval before any agent write action. The separate Engineering Copilot grounded in technical manuals, specs, standards and Git is more useful than a general CompanyGPT for most Mittelstand engineering teams. Budget for hardware, IT ownership and a scoped deployment conversation rather than a credit card checkout, and expect to weigh it

Skip BunkerAI if you have no GPU hardware, no internal IT owner, and no requirement that your documents and prompts stay inside your own network — a cloud assistant will get you further faster.
You own the hardware: the GPU server in your rack is a capital purchase that sits outside whatever deployment fee BunkerAI quotes.
That puts the total cost in the same bracket as owning server hardware plus a services engagement, rather than the per-seat math of cloud assistants like Microsoft 365 Copilot or ChatGPT Enterprise. It is likely to look expensive against a SaaS subscription and reasonable against a bespoke enterprise AI project, but you cannot tell without the

About BunkerM
BunkerAI deploys private AI infrastructure inside your own network rather than in a public cloud. The stack is three layers: a GPU server installed in your rack running Linux, a container runtime, model serving, monitoring, backups and authentication; a permission-aware retrieval layer over your documents and systems (SharePoint, file servers, PDFs, Office documents, wiki/Confluence, ERP, CRM, databases and Git); and a web AI portal plus chat assistant and agents that staff use in plain language. By default nothing is sent to an external model — inference, storage and the vector database all sit on hardware you own. The product line splits into applications rather than one generic assistant. The Company Knowledge application answers questions across manuals, PDFs, SharePoint and the internal wiki with citations to the exact document and page. The Internal AI Assistant is a private CompanyGPT for writing, summarising, translating and drafting reports. A separate Engineering Copilot grounds answers in technical manuals, specifications, standards, CAD documentation and Git. AI over Operational Data reasons over production data, logs and sensor history — the homepage's own example is "why did line 3 raise three temperature alarms yesterday?" — and BunkerAI backs this with its BunkerM industrial and MQTT experience. Agents can create a maintenance ticket or find invoices above a threshold from a supplier and summarise discrepancies, but human approval is required before any write action. Governance sits in the retrieval layer rather than on top of it. Access rights are respected, so an employee only sees answers built from documents they are permitted to read, alongside SSO, RBAC and a full log of every query and action. Air-gapped deployment with signed offline updates is available. Separately, BunkerM is a free, self-hosted, open-source MQTT management platform with AI, launched to reach beyond BunkerAI's enterprise deployments. Mittelstand manufacturers, engineering firms and mid-size companies with confidential documents are the target. Deployment is sold as standardised building blocks — BunkerAI states that about 80 percent of every deployment is the same and only the last 20 percent is tailored. Scope and pricing are worked out on a direct call. For teams that just want a cloud chatbot, this is heavier than necessary; for anyone who cannot legally send specs and contracts to a third-party API, that weight is the point.
Behind the Verdict
BunkerAI's honest differentiator is architecture, not model quality. The homepage says it plainly: local inference, local storage, local vector database, no outbound AI traffic unless you enable it. That is a statement about where data sits, and it is the thing a German Mittelstand manufacturer with confidential specs, contracts or quality manuals actually needs to solve. Strengths. The permission-aware retrieval layer is the part worth examining closely. BunkerAI states that retrieval respects your existing access rights, so an employee only sees answers built from documents they are allowed to read, and that SSO, RBAC and a full query and action log sit alongside it. Source citations point to the exact document and page — that is the difference between an assistant people trust for a quality manual and one they quietly ignore. The write path is deliberately conservative: agents can create a maintenance ticket or summarise supplier invoices, but a human approves before any write action. Air-gap deployment with signed offline updates is available. Deployment is described as standardised building blocks where roughly 80 percent is identical across customers and 20 percent is tailored, which is the right shape for a firm that does not want a bespoke research project. And BunkerM, the free self-hosted open-source MQTT management platform with AI, is a genuine on-ramp for teams that want to try the operational-data side before committing to a full deployment. Weaknesses. This is infrastructure, and it behaves like infrastructure. You need a GPU server in a rack, Linux and container runtime competence, and an internal owner who will keep the stack running after handover. The homepage does not name the specific open models it serves — it says "modern open models" and lists general, reasoning, embedding, vision and speech model categories — so if a specific model version matters to your procurement or compliance review, that is a question for the assessment call. Write actions are staged for operator approval, which adds latency if you were hoping for fully autonomous remediation. Answers depend on how well your documents are organised and permissioned in the first place; a messy file server produces a messy assistant. Where it fits. Regulated manufacturers, engineering firms and mid-size companies where the blocker is data protection, contractual exposure or board-level digital sovereignty rather than AI capability. Teams already reasoning over MES or historian data and wanting natural-language access without shipping that history to a vendor. Organisations that have banned ChatGPT internally and want to offer a controlled alternative instead of a prohibition. Where it does not. Cloud-first teams that want per-seat SaaS and no hardware to own. Small teams that only need document search. Anyone unwilling to commit internal staff time to run the stack after handover. And teams whose real problem is document findability — BunkerAI will not fix a

Real-world workflow fit
Concrete scenarios for the personas BunkerM actually fits — and what changes day-one when you adopt it.
Ask the Engineering Copilot which component fits a requirement, or what changed between two revisions of a technical manual, and trace each answer back to the cited page.
Outcome: Spec questions get answered without hunting through PDFs, and the citation lets the engineer verify before acting.
Ask why line 3 raised three temperature alarms yesterday, and receive reasoning over production logs and sensor history rather than a dashboard readout.
Outcome: Root-cause questions get an evidence-backed answer, and any corrective write action is staged for human approval first.
Deploy the private workspace so employees get a ChatGPT-class assistant over internal documents, with SSO, RBAC and a full log of every query and action.
Outcome: Staff stop pasting confidential material into public tools, and every query remains auditable.
Use Cases
- Query live equipment status and parameters in natural language without navigating dashboards.
- Generate shift reports by asking what happened during a given period.
- Receive proactive alerts when sensor readings exceed thresholds, even without active queries.
- Issue and confirm setpoint changes with a human-in-the-loop approval step.
- Maintain tamper-evident audit logs for regulatory compliance (ISO 9001, IEC 62443).
- Monitor multi-site building automation with energy efficiency goals.
- Ask which spec or component applies to a specific machine using the Engineering Copilot.
- Let employees use a controlled internal assistant instead of pasting documents into ChatGPT.
Limitations
- Requires locally deployed AI infrastructure, so you need on-premise GPU/CPU capacity and someone to own it.
- Write commands are staged for operator approval, which adds latency if you want fully autonomous remediation.
- Deployment complexity and infrastructure requirements are significant, and the homepage positions deployment against a private AI assessment rather than a self-serve install.
- Answers are only as good as your document permissions and filing discipline.
- The vendor describes "modern open models" and model categories (general, reasoning, embedding, vision, speech) but does not name specific model versions on the page we reached, so confirm that detail on the assessment call.

Where the pricing makes sense
The company stage and team size where BunkerM's pricing actually pencils out — and where peers do it cheaper.
That puts the total cost in the same bracket as owning server hardware plus a services engagement, rather than the per-seat math of cloud assistants like Microsoft 365 Copilot or ChatGPT Enterprise. It is likely to look expensive against a SaaS subscription and reasonable against a bespoke enterprise AI project, but you cannot tell without the
Setup time & first value
How long it actually takes to get something useful out of BunkerM — broken out by persona, not the marketing-page minute.
Not a same-day install. Expect a scoped assessment first, then hardware racking, Linux and container runtime setup, model serving, monitoring, backups and SSO/RBAC configuration before the first users log in. Ingestion and permission mapping across SharePoint, file servers, wikis and Git follows. BunkerAI claims about 80 percent of a deployment is standardised, which shortens the build, but the
Switching to or from BunkerM
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From public AI tools like ChatGPT or Gemini: deploy a private workspace over your own documents so staff have a sanctioned internal assistant instead of pasting sensitive material into a public service.
- →From a cloud Copilot deployment: move inference and the vector database onto your own hardware while keeping the same question-answering workflow over SharePoint and Office documents.
- →From manual document search on file servers: index SharePoint, file servers, PDFs, Office documents and wiki content so answers arrive with a citation to document and page.
- ↗To a cloud AI assistant such as Microsoft 365 Copilot or ChatGPT Enterprise: accept third-party processing in exchange for per-seat pricing and no hardware to own.
- ↗To a general-purpose cloud chatbot plus your own document store: cheaper to start, but you lose permission-aware retrieval and the local-only data path.
- ↗To an in-house build on open models: more control over model choice, but you take on the full retrieval, permissioning and operations stack yourself.
