Quick answer: A private AI is a custom LLM trained on your own documents and running on infrastructure you control — so you get a ChatGPT-grade assistant that knows your business, without your data ever leaving it or training someone else's model. Brixx Digital builds it as a system you own. Published starting prices: a Core Build from $5,000, quoted from a Blueprint (from $1,500, credited toward the build).

Your team already pastes customer details, contracts, financials and internal docs into public AI tools, because it saves them time and the work is better for it. The problem isn't the AI; it's where the data goes. On the public tools you don't control where it's stored, who can see it, or whether it's used to train the next model. For anything sensitive — client records, pricing, legal, health, anything under an NDA — that's a risk you can't paper over with a policy nobody reads.
A private AI closes that gap. We build you your own model: trained on your documents, running on infrastructure you control, answering in the context of your actual business. Same leverage your team already wants — drafting, answering, summarizing, analyzing — except the data stays inside your walls, nothing is used to train anyone else's model, and the system is yours to keep. Not a subscription that can change its terms next quarter. Yours.
If your team keeps asking the same questions, re-reading the same documents, or pasting the same context into a chatbot, it's a candidate. A few of the private-AI builds we're asked for most:
→ An internal assistant trained on your SOPs, contracts and history: ask it anything, get the answer with the source, in seconds instead of a Slack hunt.
→ Point it at thousands of files, policies or past projects and ask plain-English questions — it cites the exact document it pulled from.
→ Proposals, reports and replies drafted in your language, from your real numbers and templates — not a generic guess.
→ Summaries, trends and “what changed” across sensitive data that you'd never paste into a public tool.
→ Reads incoming requests against your knowledge base, drafts a grounded reply, and flags what truly needs a human.
→ Plugged into your CRM, portals and automations, so the intelligence lives where the work already happens.
The whole point of a private AI is control, so we're specific about what that means. Your data is handled privately and is never used to train a third party's model. The system runs on infrastructure you control, with your own keys, so you own both the model and its running costs outright. We can sign an NDA before we ever see a document. And because you own it, there's no per-seat subscription that climbs as you grow or changes its terms on you next quarter.
We're not promising magic, and we'll tell you where a private build is overkill. What we promise is a specific, inspectable system: you see what it was trained on, you see where each answer came from, and you keep the keys.
A private AI is a custom build: it starts from a Blueprint (from $1,500) that scopes it, then a Core Build from $5,000, quoted to what you actually need.
Model, data volume, hosting and access needs all move the number, which is exactly why we scope it in the Blueprint before quoting, rather than guess.
| Stage | What it covers | Published starting price |
|---|---|---|
| Blueprint | Your use case, data, model and hosting mapped into a buildable, costed spec | From $1,500, credited toward the build |
| 30-day pilot | A working private assistant on a focused slice of your data | Pilot fee credits toward the build |
| Core Build | The full private AI: model, your documents, interface, access controls, wired into your systems | From $5,000, quoted from the Blueprint |
| Care Plan | Monitoring, model and document updates, and support after launch | From $150/mo, optional |

If your data isn't sensitive and off-the-shelf is enough, a ChatGPT Team or Copilot subscription is cheaper and faster than a private build.
A private AI earns its cost when the data genuinely can't leave your control, when you need answers grounded in your documents with citations, or when per-seat subscriptions climb with headcount while you'd rather own the system once.
No. Your documents are used to make your assistant better, and nothing else. The system runs on infrastructure you control, your data is handled privately and never shared, and we can sign an NDA before we see a thing.
You own it. It's a build, not a seat you rent. You keep the system and the keys, you run it on infrastructure you control, and you own the ongoing model and hosting costs directly — no per-seat pricing that climbs as you grow. An optional Care Plan is there if you'd rather we keep it updated and monitored.
Whatever fits your needs and budget, scoped in the Blueprint: a top commercial model via your own private key, or an open model you host yourself for maximum control. We match the model to the sensitivity of the data and the job it's doing.
We build it to answer from your documents and cite the source, so you can verify every answer rather than trust a black box. No system is perfect, which is exactly why citations and access controls are part of the build, not an afterthought.
With a Blueprint that scopes your use case, data and hosting into a costed plan, or a 30-day pilot on a focused slice of your data. The Blueprint fee credits toward the build.
