Strip the identities out of your text before it reaches ChatGPT / Claude / Gemini — a model running on your own machine finds the names, orgs, places and quasi-identifiers, replaces them with stable tokens, and keeps the only key-back-to-reality on disk. When the cloud answers in tokens, you put the real identities back locally. Best-effort de-identification — not legal anonymization or a privacy guarantee.

Masking only the names you already know leaks everything you don't: an unregistered name, an employer, a city + a rare title, a project codename. Pattern-based redaction never sees those at all. vault-engine puts a local model in front as the detector, so the semantic identifiers get caught too — and nothing but the sanitized text ever leaves. How it works Benchmark How much identity each detector actually catches, on a labelled bilingual dataset (reproduce with python eval/run eval.py ; methodology in eval/ ): 77 gold identities across 15 bilingual documents — easy PII plus hard cases (ambiguous common-word names, abbreviations, transliterations, @handles, a bad","default_branch":null,"files":null,"tree":[],"storefront":"/r/fishonbike","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/fishonbike/vault-engine/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
