Private ChatGPT is a secure, enterprise-grade generative AI assistant that gives your staff all the productivity benefits of ChatGPT without the risk of confidential data leaking into the public domain.
Unlike the consumer version of ChatGPT, Private ChatGPT runs within your organisation’s own secure cloud environment, is trained on your internal documents and knowledge base, and ensures that nothing your team types or uploads is ever shared with external AI systems or used to train public models.
UK organisations across legal, financial services, housing, social care, and the public sector use Private ChatGPT through the KnowledgeFlow platform to boost productivity, improve consistency, and give staff a trusted AI tool they can actually use without fear.
Your Staff Are Already Using Free AI – The Question Is Whether It’s Safe
Here’s something worth considering. Right now, members of your team are almost certainly using the public version of ChatGPT to do their jobs. Drafting emails. Summarising documents. Researching topics. Writing reports. Interpreting policies.
And why wouldn’t they? It’s fast, it’s capable, and it makes their work easier.
The problem is what happens to the information they type in. Public ChatGPT is designed to learn from its conversations. When your staff paste in client data, internal documents, confidential
case notes, or sensitive communications,that information enters a system you have no control over. It can be used to train public AI models. It can be accessed by OpenAI. In regulated sectors – legal, financial, health, social care – that’s not a theoretical risk. It’s a compliance issue.
Private ChatGPT solves this completely. Your team gets the same intuitive, conversational AI experience they already know and use – but entirely within your own secure environment, with your data staying exactly where it should.
What Private ChatGPT Does
Private ChatGPT gives your staff a familiar, easy-to-use AI assistant that they can trust with sensitive information. Because it runs within your own infrastructure and is trained on your own documents, it’s not just safer than public ChatGPT – it’s more useful.
Here’s what your team can do with it:
- Draft and refine communications – emails, letters, reports, proposals – written in your organisation’s tone and style, not generic AI language
- Summarise long documents – upload contracts, policies, reports, or case files and get an accurate, concise summary in seconds
- Interrogate your knowledge base – ask questions about your internal procedures, guidance, or documentation and get cited, accurate answers
- Research and analysis – explore topics, synthesise information, and generate first drafts without any of the data risk of public AI tools
- Consistent outputs – because Private ChatGPT is trained on your content, communications reflect your house style, terminology, and standards
Everything happens within your secure environment. Nothing leaves. Your IT and compliance teams stay in control.

Who Private ChatGPT Is For
Private ChatGPT is Leading AI’s most widely adopted product – and that’s because the need it addresses is universal. Every organisation with staff who handle sensitive information and want to use AI productively faces the same dilemma. Private ChatGPT resolves it.
For professional services firms – law firms, accountancies, consultancies – client confidentiality is non-negotiable. The risk of sensitive case information, financial data, or privileged communications entering a public AI system is simply not acceptable. Private ChatGPT gives fee earners and support staff a powerful AI tool that works within the firm’s security and compliance requirements.
For public sector organisations – local authorities, NHS trusts, housing associations – staff are handling personal data governed by UK GDPR and sector-specific regulations. Public AI tools create real compliance exposure. Private ChatGPT removes that exposure while giving frontline and administrative staff the AI productivity benefits they need.
For charities and third sector organisations – donor data, beneficiary information, and sensitive casework require the same level of protection as any regulated sector. Private ChatGPT gives charity teams a safe, effective AI tool without the reputational and legal risks of public alternatives.
For HR and operations teams across all sectors – handling employee data, disciplinary matters, performance reviews, and sensitive internal communications demands discretion. Private ChatGPT lets HR professionals use AI to draft, summarise, and analyse without any risk to data privacy.
A Leading International Law Firm – Protecting Client Confidentiality With Private ChatGPT
An international law firm with over 20 years’ experience representing national and international clients faced a problem that will be familiar to many professional services organisations.
Their staff had a large internal knowledge base – company practices, legal rules, regulatory frameworks – that they needed to interpret and apply to individual cases every day. The firm became aware that staff were using public ChatGPT to interrogate and summarise this internal documentation. The risk was clear: confidential company information and client data was potentially entering the public domain through an uncontrolled, external AI system.
Leading AI built a private, secure, enterprise-level AI knowledge base trained on the firm’s internal documentation and selected legal rules and regulations. Staff gained fast, private, and secure access to the guidance and information they needed – without the data risk.
The results were immediate. The solution streamlined the process for finding and summarising accurate information, enabling staff to respond to queries more quickly and effectively. Crucially, it also produced more consistent internal and external communications – written in the firm’s own tone and style, not generic AI language.
The firm’s IP stayed protected. Their staff got a better tool. Their compliance team got peace of mind.

Frequently Asked Questions
How is Private ChatGPT different from the public version of ChatGPT?
Public ChatGPT is operated by OpenAI and may use your inputs to improve its models. Private ChatGPT runs entirely within your organisation’s own secure cloud environment – your data never leaves your infrastructure, is never shared with OpenAI or any third party, and is never used to train external AI systems.
What data can Private ChatGPT be trained on?
Private ChatGPT can be trained on any internal documents you choose – policies, procedures, handbooks, case studies, legal frameworks, templates, and more. You decide what goes in, and you control what your team can access.
Is Private ChatGPT compliant with UK GDPR?
Yes. Because all data is processed and stored within your own secure infrastructure, you retain full data controller responsibilities and there is no third-party data transfer to manage. Leading AI is ISO 42001 and ISO 27001 certified, and our deployments are fully auditable.
Can it be used on mobile devices?
Yes. KnowledgeFlow – which powers Private ChatGPT, is built with a responsive, mobile-first design – your team can access it securely from any device
