When a public tool is fine

  • Public research with no company or client facts.
  • Generic writing with no confidential information.
  • A workflow your advisers have approved for a defined data class.

Why private AI

Private AI, not public AI. Six reasons.

Your data stays yours

Nothing your team types, uploads, or asks ever reaches a public AI provider. It lives on your machine, in the United States.

Trained on your business

USA-sourced open-weight models, trained on your documents, your process, and your voice, so the answers are yours, not generic.

Nobody else's model, nobody else's prompts

Your AI runs for your company alone. No shared model, no one else's data in it, no one else's questions on it.

No per-seat meter

One private AI for the whole team. Add people, not subscriptions.

Terms that cannot change on you

No policy update from a provider can change where your data lives or what it can be used for.

Built and managed for you

We set it up, train it on your business, host it, secure it, and keep it current. You use it.

How it works

From first conversation to everyday use.

    Updates, security, support, and new use cases. Quoted in your assessment.

How we handle wrong answers

What happens when your AI is wrong.

It will be, sometimes. Here is how it is built so that being wrong is cheap to catch and never reaches a client.

Every answer shows its source

The passage comes from your document. Your retrieval system pulls it from the actual file. Your model does not write the source passage.

It says 'I don't know'

When your documents do not contain the answer, your AI says so instead of guessing.

A person approves anything that leaves

Nothing goes to a client without approval from your named reviewer.

You get your own number

The first ninety days record how often drafts are accepted without correction, workflow by workflow. You decide where to rely on your AI.

Your people can talk to it. Only administrators can change it. Every question, answer, and change is logged.

Your AI can only see what you can already open. Permissions come from your systems, not from the AI.

It learns how your firm writes. It looks up what your firm knows, one question at a time, only from documents the person asking is allowed to open.

How trust and control work

Choose the boundary that fits your work.

Both tracks run on NVIDIA and Apple hardware hosted in the United States. Cloud is hosted in a US data center. In-Building is installed in your building. PrivateStride provides technical and implementation support, not legal advice or a certification of compliance.

Your questions, answered.

Does turning off training make ChatGPT private?

It controls whether eligible new conversations are used to improve the provider’s models. It does not move processing into your building or onto an AI dedicated to your company. Data handling, retention, access, and terms are separate questions for the exact product and tier.

Is ChatGPT Team safe for client data?

Business tiers do not use business inputs and outputs for training by default. That does not decide whether a particular client-data workflow is appropriate. Review the exact product, account, data class, access, retention, and terms with your advisers before using client data.

What is a private AI, exactly?

An AI that runs for your company alone. PrivateStride uses USA-sourced open-weight models, trained on your documents, your process, and your voice. Choose Cloud in a US data center or In-Building in your building. Nothing your team types, uploads, or asks reaches a public AI provider.

Do we lose model quality with open-weight models?

Models are selected for the approved workloads. Outputs are drafts a professional reviews. The assessment identifies the work your AI needs to support. We do not assume one model is the right choice for every task.

Can we keep ChatGPT for some things and use private AI for others?

Yes. Public research and generic writing can stay in an approved public tool. Company or client information belongs in the environment approved for that data class. Your advisers should approve the defined workflows and boundaries.

How long until we are running?

Start with a 30-minute fit call. Either assessment takes two weeks, remotely, and produces a written report. The report scopes the implementation or installation schedule. No sandbox, trial, or demo is provided. No AI system is delivered until implementation is paid.
