Oxtractor
An Oxford University Innovation portfolio company

AI research you can check, built for work that matters.

Oxtractor is a boutique AI research and development company in Oxford. We design multi-agent retrieval and conversational AI systems for medicine, science, education and regulated industry, and we take them from the laboratory into practice with university and industry partners.

Evidence, connected

Approach

How we work

We are a small team by design. Every system we build starts as a research question, is tested against evidence, and is shaped with the people who will rely on it.

Grounded

Answers are built from retrieved sources, cited back to the document, table or figure they came from.

Checked

Independent judge and compliance agents review each answer before a person sees it, and we measure how often they catch errors.

Sovereign

Sensitive institutions keep their data. Our systems run on premise or in sovereign infrastructure and work with any foundation model.

Collaborative

We work alongside universities, clinicians and domain experts, and publish what we learn.

Research

The AI Scientist

Our current programme, run with MSc researchers at UCL's Department of Computer Science, asks what an AI agent must prove before a laboratory relies on it. We frame the answer as three tests.

Test one

Reading

Can it find and use the right evidence?

Agents that search the literature, call scientific tools and choose how to retrieve from long documents.

  • Tool-augmented research agents
  • Retrieval configuration for long contexts
  • Multimodal retrieval over tables and figures
Test two

Trusting

Can its claims be checked?

Methods that locate unsupported statements, audit reasoning claim by claim and trace how agents reached an answer.

  • Evaluation metrics for RAG
  • Claim-level auditing
  • Multi-agent trace auditing
Test three

Sharing

Can institutions improve it together?

Ways for hospitals and laboratories to fine-tune a shared model without pooling their data.

  • Federated fine-tuning
  • Reproducibility under uneven data
  • Robustness when partners drop out
Where we come from

Oxtractor grew out of information extraction research at the University of Oxford's Department of Computer Science, including the ERC-funded DIADEM project on automated web data extraction and our own work on structured aspect extraction.

Today that lineage continues in retrieval, reasoning and verification for large language model systems.

Platform

Oxtractor Nucleus

One research platform underneath everything we build. It is independent of any single industry or foundation model: domain knowledge arrives as packs, and the same verified core serves each partner.

Architecture

J6

Our multi-agent retrieval architecture. A router chooses the retrieval strategy, a reasoning agent assembles the answer, and compliance and judge agents check it before it is returned.

Product

Deep Conversational AI

Conversational AI and tutoring for learning and research, co-designed with clinicians and educators, with a current focus on medical and scientific training.

Evaluation

Verification suite

Benchmarks and auditing tools that measure grounding, error detection and consistency, so partners know a system's limits before it goes live.

Domains

Where we focus

We choose fields where answers must be traceable and mistakes are costly.

Healthcare and life sciences

Clinical knowledge support, multi-hop medical question answering and literature-aware assistants, built with practising clinicians.

  • Primary care
  • Rehabilitation medicine
  • Reproductive medicine

Scientific research

Agents that read the literature, generate and test hypotheses, and report what they found with the evidence attached.

  • Literature review
  • Experiment planning
  • Result verification

Education

AI tutoring, curriculum mapping and AI literacy programmes for universities and medical schools.

  • Tutoring dialogue
  • Curriculum mapping
  • AI literacy

Finance and law

Document review and compliance checking where every conclusion has to cite its rule and its source.

  • Trade finance compliance
  • Regulatory review
  • Legal research
Partnering

Ways to work with us

Oxtractor is a research and development company. We do not sell subscriptions; we build systems and evidence together with partners.

Joint R&D

A shared research programme on a problem your organisation owns, with clear milestones and published results where possible.

Research consortia

We join and lead grant-funded consortia with universities, hospitals and industry in the UK and Europe.

Applied programmes

We adapt Nucleus to a partner's domain, data and infrastructure, and deploy it inside their walls.

Licensing

Our architectures, evaluation methods and domain packs are available to license for partners who build in house.

Partners

In good company

Our work is anchored in two of the UK's leading computer science communities.

Portfolio partner

Oxford University Innovation

The University of Oxford's research commercialisation company. Oxtractor is part of its portfolio.
