// 01 / BROWSER · PROTOTYPE

Mask before you paste into AI.

The Shield prototype runs the Go detector as WASM on your device. Put text in its side panel, inspect visible masks, copy the redacted text and restore values in the reply.

How the path works.

01

Detect

Kennitölur, emails, IS IBANs, cards, phones, a limited set of demo name forms and up to 32 exact local terms.

02

Mask

140182-8858 becomes ⟦KT-1: XXXXX-XXXX⟧ in this illustration. Real values stay in browser memory.

03

Restore

Paste the model reply into the side panel; the local session map restores the values.

Current status.

The prototype is manual. Unfamiliar patronymic-shaped names and some address shapes block for review; other forms may still be missed. It does not intercept submissions on ChatGPT, Claude or Gemini, and it does not cover files or images.

Evidence and limits.

Detection is measured on a small synthetic corpus. It does not predict results on real data.
