Finally use AI on your sensitive files. Without the risk. Fully offline.
promptShield removes sensitive information from your documents before you share them with any AI — locally, in seconds, with no data ever uploaded.
Right now, someone on your team is pasting client data into an AI nobody approved.
That's Shadow AI — not a strategy, but a habit every professional and organization needs to eliminate. Not by banning AI, but by making it safe to use on the work that matters.
The avoiders
"We just don't paste client data into AI."
Real work stays outside AI. The productivity gap grows silently.
The risk-takers
"I'll paste it anyway — nobody will know."
Shadow AI. One incident away from a compliance crisis.
The workarounds
"I manually delete names before I paste."
Time-consuming, error-prone, no audit trail — and it still makes the AI worse.
Two steps. That's the whole flow.Faster to watch than to read about.
One pass finds what's sensitive and swaps it for safe codes — then restore it whenever you want, all on your own machine.We could write three paragraphs explaining how it protects your document. Or you could press play.
- 01Protect
Names, IDs, emails — found and swapped for consistent codes the AI can follow, in one pass
- 02Decode
Restored to real names on your machine
The interactive demo is built for a bigger screen — open promptShield.ca on a laptop or desktop to try it live.
Works out of the box.
Every other tool that does this was built for developers. This one was built for you — download, open, protect your first document.
100% offline. Your documents never leave your device — not even in this demo.
Protect, ingest, restore
promptShield encodes sensitive data before it ever reaches an AI. Feed the protected document to any LLM, then decode the output to get real results, with zero data exposure.
From sensitive document to AI insight — and back.
The complete workflow. Protect your document, put it to work with any AI, and bring real data back — all on your machine.
Your client's file keeps growing.Your AI conversation grows with it.
The Library is where every file lives — Protect, Decode, and your AI conversations all start from there. And because real work doesn't fit in a single document, every time the same entity reappears across new files, promptShield gives it the same code instantly — across every document, and across every conversation with your AI.
On your customer's side
In your AI conversations
Drop new documents into the folder whenever your client sends them. They inherit the existing code registry instantly — no re-coding, no mental remap, no broken references.
[P0ABCD] means the same person in Monday's chat and next month's chat. Your AI never loses the thread, even across sessions, weeks, or model upgrades.
One folder per client. One code per entity. Your tooling finally scales the way your client relationships actually grow.

Compliance, built in
Because nothing ever leaves your machine, the hardest parts of GDPR, HIPAA, and data-residency rules simply don't apply.
GDPR Compliant
No personal data is transmitted, stored, or processed externally. All sensitive data detection and redaction happens locally on your device.
HIPAA Ready
No PHI ever leaves the machine. Zero network transmission eliminates the need for a BAA with promptShield.
Air-Gapped Processing
Works fully disconnected from the internet. Deploy in secure environments, classified networks, or air-gapped workstations.
Zero Data Retention
No documents, codes, or sensitive data are stored after processing. Nothing is logged, cached, or sent to any server, ever.
Every license, under control
Track renewals, organize by tag, and keep base licenses out of the way — all from one dashboard.

Hope is not a plan.
Buying anonymization software is step one. Unless you can see who's actually using it, you're just hoping the team is compliant — and hope is not a control.
