Chat with ChatGPT,
now through Minac.
Cloud answers. Private data.
A private AI gateway that strips personal data out of every cloud-bound prompt and restores it in the response — so your team gets frontier models without handing over its PII.
the basics
What is PII — and how Minac handles it.
PII (personally identifiable information) is any detail that can identify a real person — on its own or combined with other details. Minac detects it on your own hardware, replaces each value with a typed placeholder before the prompt leaves your network, and restores the originals in the reply. The cloud model only ever sees the placeholder.
detected locally · replaced before egress · restored on return
what minac does
Frontier models, on your terms.
Minac sits between your people and the cloud LLM. The model sees only placeholders; your data never leaves the building intact.
Stripped on egress
Every cloud-bound prompt is scanned and personal values are swapped for placeholders before anything leaves your network.
Returned intact
When the answer comes back, Minac restores your original values — and blocks any new PII the model tries to invent.
An audit trail
Compliance and security teams get a quiet, factual record of what was protected, without the security theatre.
the signature
You see your data. The cloud sees placeholders.
The privacy mechanism is made visible — detected values are underlined, named, and replaced. Nothing dramatic; just honest.

Only the placeholder text reaches the cloud model.
Your values return in the reply; you never lost context.
voice in, safely
Dictate and attach audio — still private.
Voice notes and recordings are transcribed on your hardware, then the transcript runs through the same sanitizer before any of it reaches the cloud.
Call Dana Whitfield back about account GB29 NWBK 6016 before Friday.
documents & images
PII redacted in the pixels, not just the text.
Attach a scan, a photo, or a PDF. Minac strips embedded metadata, reads the page with on-device OCR, and black-boxes any detected personal data before the file is forwarded.

Subject: Prompt test data for HR assistant pilot
Hi ,
I wanted to share a quick update on the HR assistant pilot and the prompt test data we plan to use next week.
The pilot will start with onboarding, payroll, and internal support scenarios. We need to confirm the assistant can identify and handle personal information correctly, especially when the data includes Finnish characters such as ä and ö.
Prompt 1:
"Create an onboarding checklist for employee employee ID . Her private email is"
Prompt 2:
Prompt 3:
"Draft a support reply to about her locked HR account. Include her last login IP , recovery phone , and office location"
Best regards,
HR Systems Manager, ACME HR Solutions

redacted copy saved · original never leaves your network
three modes
As much control as the moment needs.
Pick how visible the sanitizer is for each message.
Detect and replace PII silently on every message.
Review what will be sanitized before each send.
Sanitization disabled. Messages are sent as written — for non-sensitive work.
review mode
Tag anything as sensitive — not just the obvious.
Auto-detection catches names, emails, and IDs. In Review mode you can highlight anything else — a project name, a client, a phrase — and tag it so the cloud only ever sees a placeholder.
