Isolated
You type inside a secure ChatWall window that the host website cannot access. Your original text is never exposed to the chat site — only the already-masked version is pasted in.
⚠️ Other tools mask inside the chat input — still accessible to the chat's website scripts. ChatWall's overlay keeps your text fully out of the host page.
100% Local Processing
Anonymization happens entirely on your device (Browser) or private server (On-Premise). Your sensitive data never leaves your device—neither to the AI provider nor any third party.

⚠️ Other tools send your data to external servers to mask it — a risk if their server is compromised. With ChatWall, all processing runs entirely in your browser.
Data Exposure Prevention
Detects and masks 25+ sensitive entity types (IBAN,
SSN, API Keys) using local regex & NLP.
Missed something? You can mask data
manually and save it to your favorites for automatic detection next
time.
Reversible Unmask "Deanonymization"
The AI answers with tokens (`[NAME_1]`). ChatWall restores the original names instantly in a secure overlay window (`[NAME_1]` -> John Doe).
