Local AI that finds sensitive files on your Mac before attackers do VaultSort 4.4.0 introduces Guardian, a local AI tool that scans Mac folders for sensitive files like identity documents, financial records, credentials, and medical files entirely on-device with no uploads or network calls. The $24.99 one-time purchase app runs read-only scans, ranks findings by severity, and offers one-click encryption via Touch ID or YubiKey, with no persistent storage of reports. Home / Guardian Find what should be locked. Lock it. Guardian scans the folders you choose for identity documents, financial records, credentials, and medical files — entirely on your Mac. Nothing is ever uploaded.

For exactly the files Guardian looks for, that's self-defeating — you'd be handing your tax returns to a cloud API to find out they're exposed. Guardian runs entirely on your Mac instead. Zero uploads, zero network calls The analysis happens on-device, including reading text inside images. Nothing about your files leaves your Mac during a scan. Read-only by design Guardian never moves, changes, or deletes anything on its own. It reports what it finds — you decide what happens next. Nothing is stored The report lives only in memory. Guardian doesn’t create a persistent map of your sensitive files on disk. Four kinds of files Guardian watches for. A detected number pattern, a filename that says what it is, or on-device AI reading the content — Guardian looks for the files that shouldn't be sitting out in the open. Identity documents Passports, driver’s licenses, Social Security cards — scans and photos of the documents that prove who you are. Financial & payment details Bank statements, tax returns, card numbers — anything that describes or accesses your money. Credentials & keys Password exports, recovery codes, SSH and API keys — the files that unlock everything else. Medical & legal records Medical records, prescriptions, contracts, legal filings — documents that are nobody else’s business. Copy we stand behind: Guardian flags files that likely hold sensitive information — never “finds all sensitive files.” A strong first pass, not a guarantee. Find it. Review it. Lock it. From “I had no idea that was there” to locked, in about a minute. Choose folders Point Guardian at Desktop, Downloads, Documents — any folders you want reviewed. You decide the scope. Scan on-device Guardian reads file contents and metadata locally, ranks findings by severity, and flags any sitting in a cloud-synced folder. Encrypt in one click Select the findings you care about and hand them straight to Encrypt. Confirm with Touch ID or your YubiKey — done. Your files never leave your Mac. An app that finds your most sensitive files must never be a way for them to leak. There is no Guardian backend — we couldn't hand over what it finds even if asked, because it never leaves your machine to begin with.
