API keys, credit card numbers, and My Number identifiers block the send. Email addresses and phone numbers trigger a warning. Inspection runs on-device, and original text is not sent to LEAK GUARD's servers.","whyItMatters":"The extension treats employee use of generative AI as something to be inspected at the moment of sending rather than prohibited, which places the control point at the browser instead of the network.","webCardHtml":"\u003cp\u003eThe inspection runs in the browser at the instant a user presses Enter or clicks send, and it reads the whole input field once rather than monitoring continuously. A protection indicator sits at the bottom right of the ChatGPT screen while the extension is active.\u003c/p\u003e\u003cp\u003eDetections are handled by category. API keys and access tokens, credit card numbers, and My Number identifiers stop the original text from being sent. Email addresses and phone numbers produce a warning, and the user can confirm to send once or cancel. Attached files are not read; only file names and extensions are checked.\u003c/p\u003e\u003cp\u003eOnly masked body text is stored when a detection occurs, with the detected value replaced by a category label such as [REDACTED:EMAIL]. Administrators see a list of time, user, information type, and whether the event was a warning or a block. Body text is shown only after an explicit administrator action, and that viewing is written to an audit log.\u003c/p\u003e","blueskyPost":"LEAK GUARD blocks API keys, card numbers and My Number at send time while emails and phone numbers only warn, so the tool draws its own line between leaks it stops and leaks it flags.","twitterPost":"AI Japan's LEAK GUARD blocks API keys and card numbers outright, but emails and phone numbers only warn, so the decision stays with the user.","threadsPost":"AI Japan's LEAK GUARD treats different data as different risks: API keys, card numbers and My Number identifiers block the send, while email addresses and phone numbers only trigger a warning. That split leaves the judgment call with the employee, not the extension.","newsletterBlurb":"AI Japan has begun offering LEAK GUARD, a Chrome extension that checks what employees are about to send to generative AI services. The extension inspects the input field on-device at the moment of sending, blocking API keys, credit card numbers, and My Number identifiers while warning on email addresses and phone numbers. Only masked text is stored on detection, and administrators see detection history with body text shown only on an explicit action that is audit logged.","attributionJson":"[{\"source\":\"ASCII.jp\",\"url\":\"https://ascii.jp/elem/000/004/439/4439468/?rss\",\"title\":\"Stopping Accidental Sends to Generative AI Just Before They Happen: AI Japan Launches LEAK GUARD, a Chrome Extension for Enterprises\"}]","lintFlagsJson":null,"lintHits":0,"costUsd":0,"inputTokens":4624,"outputTokens":681,"status":"published","repairAttempts":0,"nextRepairAt":null,"factsAttemptedAt":1791176367,"createdAt":"2026-10-05T04:55:06.000Z","publishedAt":"2026-10-05T04:58:23.000Z","updatedAt":"2026-10-05T04:58:23.000Z"},"cluster":{"id":"c_4d791b996e93623c86cd90c5","canonicalTitle":"生成AIへの「うっかり送信」を送信直前に止める。AI Japan、法人向けChrome拡張「LEAK GUARD」を提供開始","representativeArticleId":"a_e71accea393fad985b0a6015","sourceCount":1,"writtenSourceCount":1,"writeAttempts":0,"isSolo":true,"entitiesJson":"{\"anime_titles\":[],\"manga_titles\":[],\"work_titles\":[\"LEAK GUARD\"],\"studios\":[\"AI Japan\"],\"people\":[],\"type\":\"announcement\",\"domain\":\"other\",\"is_roundup\":false}","contentType":"news","status":"published","firstSeenAt":"2026-10-02T00:00:00.000Z","lastSeenAt":"2026-10-02T00:00:00.000Z","updatedAt":"2026-10-05T04:58:21.000Z"},"attribution":[{"source":"ASCII.jp","url":"https://ascii.jp/elem/000/004/439/4439468/?rss","title":"生成AIへの「うっかり送信」を送信直前に止める。AI Japan、法人向けChrome拡張「LEAK GUARD」を提供開始"}],"entities":{"anime_titles":[],"manga_titles":[],"work_titles":["LEAK GUARD"],"studios":["AI Japan"],"people":[],"type":"announcement","domain":"other","is_roundup":false},"keyFacts":null}
