LLM Development

AI that knows your business, not just the internet

ChatGPT does not know your contracts, your products or your policies. We build AI applications that do — and we measure how accurate they are before you rely on them.

Capabilities

What this covers

AI assistants

Internal tools that answer questions from your own documents and systems, with a link to the source of every answer.

Document search

Ask a question in plain English and get the answer from thousands of files, not a list of search results.

Drafting and summarising

Generate first drafts of quotes, reports, emails and case notes in your own house style.

Data extraction

Pull structured fields out of unstructured text — contracts, CVs, tickets, transcripts.

AI agents

Multi-step tasks that use your tools to get work done, with approval checkpoints where the stakes are high.

Accuracy testing

A test set built from your real data, so every change is measured rather than hoped for.

Deliverables

What you get at the end

Built so your team can run and extend it without us. That is what a good handover looks like.

  • Working application deployed to your environment
  • Accuracy scores against a test set of your real data
  • Source citations on every AI answer
  • Cost per request monitoring and limits
  • Handover so your team can maintain it

Typical technology

Chosen per project against what you already run and what your team knows — never out of habit.

  • OpenAI
  • Gemini
  • LangChain
  • pgvector

  • TypeScript

How we choose technology

Ways to start

How to get started

Start small. A fixed-price first step gives both sides real information before anyone commits a build budget.

2–3 weeks, fixed price

Proof of Concept

One use case built against your real data, with an accuracy number at the end. No commitment beyond it.

From 6 weeks

Build

Full application with testing, safety checks and monitoring, deployed to your environment.

Monthly

Ongoing

Models and prompts change. We keep testing, improving and controlling the cost.

Questions

What people ask about llm development

Anything else, email hello@voxalone.com.

Will our data be used to train AI models?

No. We use business API tiers where your data is contractually excluded from training. Where your rules are stricter, we can host an open-source model so nothing leaves your infrastructure.

How do you stop it making things up?

We ground answers in your documents and show the source for each one, so anyone can check it in seconds. We also test against a set of real questions with known answers before launch, and after every change.

Which AI model should we use?

It depends on the task, your budget and your data rules. We build so the model can be swapped without a rewrite, because this field moves fast and today’s best choice will not be next year’s.

Is our data good enough for this?

Often yes, for a narrower first use case than people expect. The proof of concept tells you honestly before you spend real money.
