What our analysis found
JustDone: GPT-4o AI Writing Assistant & Grammar Checker, used by 100,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in November 2025.
Analyst notes
The extension's manifest permissions (storage, tabs, contextMenus) and content script scope (<all_urls>) are typical for an AI writing assistant. Externally connectable is restricted to [domain withheld], indicating data flows to the publisher's own domain. Disclosed data collection categories (PII, personal communications, location, user activity, website content) match expected behavior. The small scripts provided (,,,) only modify Google Docs UI or toggle a flag—no suspicious network requests or code injection. However, the main logic in bundled JS files (background., contentScript., popup., gmail.) was not provided for review, which limits confidence. No evidence of malicious intent was found in the accessible code. The ML risk score was 0.00 (low), and the third-party risk score attributes impact mainly to standard permissions. Thus, the extension is likely a legitimate grammar and writing assistant, and the flagged signals are false positives.
