Questions & Answers

As answered by people managing Acuity AutoRedact and Diffyn.

What makes your product unique?

Acuity AutoRedact's answer

Acuity AutoRedact stands out primarily due to its strict data privacy safeguards. It operates a "Zero AI Model Training" policy, meaning that uploaded client data is never used to train foundational AI models, Large Language Models (LLMs), or computer vision systems. Additionally, it implements a rigid 24-hour data retention policy, ensuring all uploaded and processed files are automatically and permanently deleted from their servers within a day.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

Why should a person choose your product over its competitors?

Acuity AutoRedact's answer

True, Irreversible Redaction: Many basic tools create "false redactions" (essentially just drawing a black box over text), which leaves the underlying metadata and code intact and can lead to hefty ICO (Information Commissioner's Office) fines. Acuity AutoRedact scrubs the underlying code, metadata, and revision histories, ensuring the data is genuinely destroyed.

Massive Cost Reduction: Manual redaction can cost UK businesses a huge amount of time or external expertise per Data Subject Access Request (DSAR). Acuity AutoRedact automates this process, bulk-redacting thousands of pages of unstructured data in minutes.

All-in-One Format Support: Instead of using separate tools, it handles PDFs, Office documents, email archives (PST/MBOX), and even CCTV/video redaction in a single platform.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

Which are the primary technologies used for building your product?

Acuity AutoRedact's answer

The platform is powered by AI-driven automation technologies tailored for document processing. This includes:

  • Optical Character Recognition (OCR) for extracting text from scanned documents and images.

Acuity AutoRedact was built by Andrew Walls, the Founder and CEO of its parent company, Acuity AI Education Ltd.

The vision of Acuity AutoRedact is to ensure that document and CCTV redaction is affordable and accessible to anyone who needs it and not locked behind prohibitively expensive subscriptions.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries.

Acuity AutoRedact's customer base primarily includes UK organisations, legal firms, corporate privacy offices, multi-academy trusts, schools, local authorities, charities, businesses and often any organisation that processes a Data Subject Access Request.
