PwC UK Uses Relativity aiR for Review and Review Centre to Reduce Review Time by Nearly 80%

How did they do it?

• Deployed a hybrid workflow blending human expertise with Relativity aiR for Review’s generative AI.
• Leveraged Review Centre to prioritise first-level review and focus human effort where it mattered most.
• Saved 110 review days and met a stringent two-week deadline.

Tackling a Complex Review at the Speed of aiR

A PwC UK client needed to identify relevant content across more than 32,000 highly technical documents – within less than two weeks. It was a familiar challenge: deliver speed without sacrificing accuracy.

PwC’s forensic technology team, known for combining deep review experience with an innovation-forward mindset, needed to accelerate the process without compromising quality. The project served as a timely opportunity to use Relativity’s generative AI review solution, Relativity aiR for Review.

Enhancing Efficiency and Confidence Through a Hybrid AI-Powered Workflow

The PwC team deployed a hybrid strategy that blended traditional review techniques with AI-driven functionality. They seamlessly integrated Relativity aiR for Review into existing workflows, allowing the team to quickly adapt to project demands without disruption.

Working closely with subject matter experts and investigation specialists, the team iteratively refined AI-prompt criteria to align AI outputs with the nuances of the case. This collaborative and controlled approach ensured confidence in the outcomes while reducing unnecessary manual review.

Using Review Centre, the team prioritised their first level review based on aiR for Review’s outputs – quickly surfacing the most relevant documents and directing human reviewers where they were needed most.

Trusted Results with Tangible Impact

aiR for Review quickly and accurately deciphered complex, terminology-heavy documents, providing precise and explainable results. This sped up the review team’s understanding of the project and allowed PwC to streamline the review process and find the relevant documents in the early stages of review.

After considering project validation statistics, it was determined that no further review was required. These efficiencies not only translated into cost and time savings, but also an enhanced service quality for the client.

As a result, the team was able to complete the review more efficiently and with fewer resources while maintaining high accuracy and consistency. This resulted in the saving approximately 110 human-days and a near 80% reduction in the overall review time, enhancing both efficiency and client confidence.

Enhancing Service Through Innovation

The project is one example of how PwC is continuing to evolve its forensic and investigative services by embedding automation and AI into existing expertise-driven workflows. By integrating tools like Relativity aiR for Review, PwC is scaling efficiency and precision – while delivering the high-quality results clients expect.

PwC is proof that when people and technology work in concert, the result is faster, smarter review – and a framework for the future.
