For auditors & assurance teams

Use AI on working papers without breaching client confidentiality.

Everything in an audit file is confidential — that's the deal that gives you access in the first place. You shouldn't have to scrub entity names out of working papers by hand before asking an AI for help — and then put them all back afterwards. That's what we do for you, automatically, before anything leaves your computer.

No card required. You land straight in a simple chat — drop a file and ask.

The answer you download has the real names put back. ✓ The AI never saw them.

How it works

Three steps. No setup, no training, nothing to install. If you can attach a file to an email, you can use this.

1

Drop your file

Drag in the working paper, board minutes, engagement letter or management representation you're working on. Before anything leaves your computer, reference numbers, IDs, emails and phone numbers are swapped for neutral placeholders automatically. Entity and person names are caught by a name-detection model that runs on your device too — and if it isn't ready yet, the send is held rather than risk a name slipping through.

2

Ask your question

"Summarise the decisions in these board minutes." "Check this schedule against last year's." "Draft the points for the management letter." The AI does its work seeing only the placeholders — never which client you're actually auditing.

Download the answer

The reply comes back with the real names restored — automatically, exactly where they belong. No find-and-replace, no un-renaming, no copy-paste gymnastics. Just the finished answer.

We can't leak your audit clients' data — we don't have it. The swap happens before your file leaves your machine, and we keep nothing afterwards: no copies of your documents, no copies of the answers. There is simply nothing on our side to breach, subpoena or lose.

Reference numbers, IDs and contact details are caught deterministically, every time. Free-form entity and person names use a small name-detection model that also runs on your device; recall is strong on common names but not perfect (unusual or non-Latin names can be missed). For your most confidential files, install the desktop app — it tokenises the file itself entirely on your own machine before anything is sent to the AI, keeps your API key and logs local, and stores tokens in an encrypted vault.

Built for people whose independence depends on discretion

Auditors are bound by professional codes of ethics — IESBA and its national equivalents — that make client confidentiality non-negotiable. These are the guarantees that make AI compatible with that code.

Nothing is stored

Your documents and the answers pass through and are gone. Zero retention — verified, not just promised.

Works with your files

PDF, Word, Excel, CSV, plain text — the files you already work in, no conversion or special format needed.

A signed receipt, every time

Each request produces a tamper-proof receipt showing what happened and what was protected. Keep it in the engagement file as evidence of your diligence.

Confidentiality-friendly by design

Because client identities never reach the AI provider and nothing is retained, using AI this way sits comfortably alongside professional codes of ethics and GDPR. See the details.

Sound familiar?

The workarounds people use today are slow — and fragile.

The manual rename. "Entity A", "Person X", find-and-replace before pasting — then reversing it all in the answer, hoping you didn't miss one instance on page 14.

The retyped summary. Typing an anonymised version of the document by hand because uploading the real one feels wrong. Half an hour gone before the AI has even started.

The quiet rule-break. Pasting the real thing and hoping it's fine. It's the fastest option — and the one that can cost you an engagement — or your registration.

The blanket ban. The firm forbids AI entirely, and the productivity gain everyone else is getting goes to your competitors instead.

Not an auditor? There's a page for you too.

The duty of confidentiality isn't unique to audit. If your clients trust you with their private affairs, this is built for you too.

Common questions

Plain answers, no fine print surprises.

Which AI does the answering?

The leading AI models — the same ones behind ChatGPT, Claude, Gemini and others. The difference is what they're allowed to see: with us in between, they get your question and a version of your document with all the identifying details replaced by placeholders. They do the thinking; they just never learn who it's about.

How do the real names get back into the answer?

The swap list — which real name maps to which placeholder — is created on your device and used to restore the answer on the way back to you. It's applied automatically, so the document you download reads exactly as if the AI had seen the real names all along.

What if I need to prove I handled a document properly?

Every request comes with a signed, tamper-proof receipt: a small certificate recording when the request happened and that the protections were applied. You can verify it independently, months later, and keep it in the engagement file.

Do you keep a copy of my files?

No. We keep no copies of your documents, your questions or the answers. Once your download completes, it exists only on your machine. That's the point: we can't leak what we don't have.

Will this stand up in a quality review?

Every request produces a signed, tamper-proof receipt recording when it happened and that the protections were applied. Keep it in the engagement file the way you keep any other evidence of diligence — a reviewer can verify it independently, months or years later. And because we keep no copy of your content in the clear, there is no second copy of your working papers sitting on someone else's server.

Is this hard to set up?

No. Create a free account and you land directly in a simple chat. Drop a file, ask your question — that's the whole workflow. Prefer to stay in the tools you already use? After you register, you can install a small browser add-on for Chrome or Firefox and keep using ChatGPT, Claude, Gemini or Grok as you do today — names, emails and account numbers are anonymised inside your browser before anything is sent, and the add-on downloads from your account page. (If your firm has an IT team that wants to connect it to internal systems, there's a full technical setup for them too, but you never need to touch it.)

Try it on a real schedule — today.

Free to start, no card required. Drop a document, ask your question, and see the answer come back with the names where they belong.
