Private by design
The text you paste is processed in your browser. It isn't sent to WHU AI or anyone else, and the key disappears when you close the page.

Private: nothing you paste leaves your device
Redact before you prompt.
Paste an email, note, or document. Names, emails, phone numbers, addresses, and ID numbers become placeholders like [NAME_1], so you can safely use any AI tool. Then paste the AI's reply back here to put the real details in.
1 · Paste your text
The sample above is made up. Replace it with your own text.
Smarter name detection
Uses an open-source model (bert-base-NER from Hugging Face) that runs on your device to find names, organizations, and places the built-in rules miss. The first use downloads the model from whu-ai.com; after that it's cached.
2 · Copy the safe version
Your key: what each placeholder stands for (stays on this device)
| Placeholder | Original |
|---|
3 · Put the details back
Automatic redaction can miss things, such as unusual names or details described in words. Always read the safe version before you paste it into an AI tool, and follow your organization's AI policy.
Open-source AI, self-hosted
Smarter detection uses an open model from Hugging Face, hosted on our own server and run on your device. No AI company sees your text.
Consistent placeholders
The same person always gets the same placeholder, so the AI's reply still makes sense and the details go back in the right places.
