One Good Engineer& Co.

Private AI for businesses

An assistant that knows your company documents, but does not decide for people.

I design and implement AI solutions for documents, knowledge and processes, with access control, cited answers and a clear place for human approval.

Service and B2B companies · Kraków and Poland. The first step is one process, not buying a server.

Cited answersA source to check, not just plausible text.
Measured choiceA local model is not the goal by itself.
No blind decisionsCritical actions require human approval.

Where companies get stuck

Documents, questions and data in one controlled process.

The value comes from connecting company knowledge to real work. A chatbot without sources, permissions and measurement soon becomes another place to check by hand.

01

Knowledge lives in documents

Contracts, procedures and instructions are scattered, and the answer depends on who remembers where to look.

02

The same questions return

The team spends time reconstructing answers instead of handling work that needs experience.

03

Data needs care

Permissions, retention, logs and rules of use matter more than the model name.

04

The choice is unclear

Local model, European cloud or ready API? It depends on data, quality and total task cost.

Four ways to work together

From a business question to a solution you can maintain.

You can order the audit, the pilot or the full integration. Scope and cost follow the process review.

01 / I do not know where to start

Data and process audit

I review one concrete process, its knowledge sources, systems and constraints. I compare changing the process, buying a tool, using an API and running a model privately.

  • Process and risk map
  • Pilot scope and measurement plan
  • Technology recommendation

The result may be a decision not to build anything.

02 / I want to test one case

Knowledge assistant PoC

I build a small, measurable prototype over legally shared documents. Answers show their sources, respect permissions and hand uncertain cases to a person.

  • Working pilot
  • Test set from real questions
  • Decision on the next direction

A pilot does not pretend to be a finished product or an automatic decision.

03 / The pilot works, now connect it

Integration with company work

I connect the assistant to email, storage, CRM, SharePoint or another system. I add roles, operation logs, error handling and approval for consequential actions.

  • Observable, testable process
  • Permissions and audit trail
  • Handover documentation

Provider dependencies and limits are clear before work starts.

04 / I have a system to maintain

Evaluation and care

I monitor answer quality, availability, cost and changes in the knowledge base. I update rules and models when measurement shows a real need.

  • Quality and cost report
  • Regression tests on real questions
  • Next-improvement plan

Care is a separate service, not a hidden subscription.

What private means

Privacy is architecture, not a sticker.

Data: Local or in a European cloud, depending on requirements and cost.

Sources: Answers point to the document and passage behind them.

Access: Users see only what they are allowed to see.

Human: Critical actions and uncertain answers go to approval.

Measurement: We test real questions, errors, latency and task cost.

Handover: Code, configuration, logs and instructions stay with you within the agreed scope.

First project

A small pilot, clear criteria and a decision after the result.

01

Choose one process

We do not start with a model. We start with a question that costs time or causes errors today.

02

Take a data sample

Using legally shared material, we define what the system can see and what a good result looks like.

03

Compare solutions

We test a local model, a European cloud and ready APIs. Local does not always mean cheaper.

04

Make the decision

You get the pilot result, tests and the cost of keeping it running. We can continue, change direction or stop.

Start with the problem

Do you have documents your team keeps searching for?

Describe where time disappears today. To start, you only need the process, never passwords, API keys or customer data.

  • A conversation about one process
  • Audit, PoC or integration as a separate service
  • Scope, cost and acceptance criteria before work starts

I reply personally. The first conversation takes 20 minutes and costs nothing.
