A Caviard alternative for documents, not just chat text
Caviard is a Chrome extension that masks personal data as you type or paste into ChatGPT and DeepSeek, on your own device, and unmasks it in the responses. If your sensitive material lives in PDFs, Word files or scanned documents rather than chat text, PiBye is the closer fit: a Mac app that prepares whole documents locally, with human review, before any AI sees them.
Key takeaway: Choose Caviard for quick protection inside supported chat pages in Chrome. Choose PiBye for client documents, scans and a reviewed copy you can use with any AI.

What Caviard does well
Caviard works where many people already are: the ChatGPT page in Chrome. Its site says “all masking happens on the user’s device. No data is sent away,” and describes two-way protection that masks data in your prompts and the AI responses you receive. A keyboard shortcut toggles between the masked and original text.
Users like how little effort it takes. One Chrome Web Store reviewer wrote: “I use it every day to find and replace sensitive data I paste into ChatGPT. It’s quick and easy.”
Where the two products differ
Facts about Caviard come from its own site, pricing page and Chrome Web Store listing, checked again on 25 September 2026.
| Caviard | PiBye | |
|---|---|---|
| Form | Chrome extension | Native macOS app (Apple Silicon) |
| Where it works | Supported chat pages; ChatGPT and DeepSeek are named | Any AI, by copy and paste or saved file; optional local connection with Claude Desktop or the ChatGPT desktop app |
| Input | Text in the chat box | PDF including scans (OCR), Word .docx, Markdown and text |
| Review | Masks automatically as you type | You approve, keep or edit every detection before a copy is ready |
| Restoring details | Unmasks in chat responses | Restores details in returned drafts and files, flagging altered stand-ins |
| Processing | On your device, per Caviard | On your Mac; no PiBye cloud |
| Price | Free for up to 10 protected values per document; $9 once for unlimited, per its pricing page | $99 CAD once, 12 months of updates |
PiBye does not work inside the browser chat box, and Caviard does not process document files, per their own materials.
Who should choose which
Choose Caviard if you work mostly by typing or pasting text into ChatGPT or DeepSeek in Chrome, want masking to happen automatically without a review step, and do not need to prepare files.
Choose PiBye if your client material arrives as PDFs, Word documents or scans, if you want to review each replacement before anything is shared, if you use Safari, Claude, Gemini or Copilot, or if you need the AI’s draft back as a restored document.
Some people could reasonably use both: Caviard for quick chat questions, PiBye for documents.
Where PiBye fits
How PiBye handles this
PiBye imports the document on your Mac, detects names, contact details, dates and ID numbers, including in scans, and shows every finding for you to approve, keep or edit. The approved copy uses consistent stand-ins such as [PERSON_001] and works with any AI.
Returned drafts come back through PiBye, which restores the real details locally.
