TESAQ AI Solutions

Private AI. Practical Intelligence. Your Environment.

TESAQ is building its AI capabilities around selecting and adapting suitable models, deploying them locally, connecting them to enterprise knowledge, and implementing AI assistants that support real work, within the boundaries your organisation sets.

Offline AI Assistants

AI assistants designed to run without a continuous internet connection after the required models and components have been installed, where supported by the deployment.

Private AI Deployment

AI architectures that can be deployed on suitable local computers, servers or private infrastructure, according to the client's security and operational requirements.

Knowledge-Based Assistants

Assistants configured to retrieve relevant information from approved organisational documents, manuals, knowledge bases and other supported data sources.

AI Integration & Customization

Integration of AI capabilities with existing enterprise applications, APIs, databases and business workflows, subject to technical feasibility.

What is achievable depends on the selected models and their licences, the deployment architecture and the hardware available. We qualify these factors with you before recommending an approach.

Service areas

How we help you put AI to work, privately.

Area A

Offline AI Assistants

Explore AI assistants that can operate locally after setup, subject to model and hardware compatibility. Once the selected model and its components are installed, suitable deployments can answer questions without sending prompts to an external AI service.

Potential applications

  • Answering questions from approved documents
  • Searching internal knowledge
  • Assisting with technical manuals and operational procedures
  • Drafting and summarising documents
  • Supporting internal staff workflows
Area B

Private Enterprise AI

AI systems deployed within an organisation's approved environment (a workstation, an on-premises server or private cloud infrastructure), with an architecture based on its security, network, access and data requirements.

What we define with you

  • Where models, indexes and logs are hosted
  • Who can access the assistant and which sources
  • Network boundaries and any external connections
  • Retention, monitoring and administrative controls
Area C

Knowledge-Based AI and RAG

Retrieval-augmented generation (RAG) retrieves relevant passages from approved documents or knowledge sources and uses them to help the model answer a question. It lets an assistant work with your organisation's information without retraining the model each time documents change.

Potential features

  • Document ingestion and indexing
  • Source-aware responses that reference the passages used
  • Access-controlled knowledge retrieval
  • Document updates and re-indexing
  • Evaluation of answer quality
Area D

Model Training and Adaptation

The right approach depends on the use case. It may involve selecting a suitable existing model, configuration and prompting, retrieval, fine-tuning, or other adaptation techniques. Most projects do not require training a foundation model from scratch.

Typical options, from lightest to heaviest

  • Model selection and evaluation against your tasks
  • Configuration, system instructions and prompting
  • Retrieval from your approved knowledge sources
  • Fine-tuning or adaptation where justified by the use case and data
Area E

Enterprise AI Integration

Connect AI capabilities to the systems people already use. Depending on technical feasibility and access policies, integration can involve supported databases, APIs, business applications, document repositories and approved workflows.

Integration possibilities

  • Supported databases and reporting data
  • Internal APIs and business applications
  • Document repositories and file shares
  • Approval and ticketing workflows
Area F

AI Discovery and Feasibility Assessment

An initial assessment establishes whether, and how, a private or offline AI assistant fits your situation before significant investment.

The assessment establishes

  • The business problem
  • Expected use cases
  • Data sensitivity
  • Offline requirements
  • Hardware and model requirements
  • Deployment architecture
  • Budget and implementation stages

Example deployment architecture

How a private knowledge assistant fits together.

A typical knowledge-based assistant, with every component running inside the approved environment.

Conceptual architecture

Illustrative: actual design depends on your requirements

  1. Step 1Approved Documents & Business DataOnly sources approved for the assistant
  2. Step 2Data Preparation & IndexingClean, chunk and index content locally
  3. Step 3Local Knowledge RetrievalFind relevant passages for each question
  1. Step 4AI Model / Inference EngineGenerates the answer on your hardware
  2. Step 5AI Assistant InterfaceWeb or application interface for users
  3. Step 6Authorized UserSigned-in staff with defined permissions

Cross-cutting, applied at every step

  • Access controls
  • Logging & audit
  • Administrative controls
This is a conceptual architecture, not a description of a specific product. To maintain the intended data boundaries, the document store, retrieval index, model inference, logs and user interface must each be configured to run within the approved environment, and any external connections reviewed and controlled.

FAQ

Questions organisations ask us about private AI.

Honest answers, because the right approach depends on your situation.
Can an AI assistant work without the internet?

Yes, in suitable deployments. Once the selected model, its runtime and the knowledge index are installed on local hardware, an assistant can answer questions without an internet connection. Initial setup, updates and some optional features may still require connectivity. Whether a fully offline deployment is practical depends on the chosen model, the hardware available and the features you need.

Can it answer questions using our own documents?

Yes. Using retrieval-augmented generation (RAG), the assistant searches approved documents for relevant passages and uses them when answering. Answer quality depends on the documents' quality and structure, how they are prepared and indexed, and the model used, so we evaluate answers against real questions before rollout. Like any AI system, it can still make mistakes, and responses should be checked for important decisions.

Can it be installed on our own server?

Often, yes. Many open-weight models can run on an organisation's own workstation or server, subject to their licence terms and the hardware's capacity. We confirm model licensing, hardware suitability and your security requirements during the feasibility assessment.

What hardware is required?

It depends on the model size, the number of concurrent users and expected response speed. Smaller models can run on capable workstations; larger models or more users typically need servers with suitable GPUs and memory. We recommend hardware after understanding your use cases rather than prescribing a fixed specification.

Does the project require fine-tuning?

Not necessarily. Many knowledge-assistant use cases are well served by a suitable existing model combined with retrieval from your documents and good configuration. Fine-tuning or other adaptation is considered when evaluation shows it adds value and suitable training data is available.

Can the assistant integrate with existing software?

Where technically feasible, yes, for example through APIs, supported databases, document repositories or a web interface embedded in existing tools. Integration scope is defined during discovery, taking access controls and data boundaries into account.

How do we evaluate response quality and security?

We agree a set of representative questions and expected answers, test the assistant against them, and review accuracy, source references and failure cases. On the security side we review access controls, where data, indexes and logs are stored, any external connections, and administrative controls. Security depends on the whole deployment (infrastructure, configuration and operational practice), not on the AI model alone.
