WritersProof

Keep a local record of your writing process, revisions, and observed AI-tool copy activity in supported web editors.

Keep evidence of how your writing developed. WritersProof records supported writing activity on your device: document-state hashes, revision checkpoints, typing timing and counts, and observed copy activity from supported AI tools. It helps writers explain their contribution, whether they work independently or use AI assistance. Start a session in a supported web editor, write and revise, then inspect or export the record. Local recording and export do not require an account. Two ways to use it: • Browser only: keep a local hash-chain record in this browser and export it as JSON. This is a limited activity record, not native hardware-backed authorship proof. • With the optional WritersProof desktop app and registered native messaging host: send supported observations to the local app. Available evidence depends on the app, platform and capabilities it actually reports. Supported editor interfaces include Medium and Overleaf, with dedicated and generic adapters for other writing sites. Site layouts can change. Generic adapters have limited verification and are labeled accordingly. Self-hosted WordPress, Ghost and other custom domains require permission in Settings. Broader site detection is optional. Direct Google Docs and Sheets document witnessing is unavailable through the ordinary page interface. A separate Google Workspace companion integration is required for supported Workspace capture; installing this extension alone does not enable it. You can still declare ownership of selected text. A selection declaration is not verification of that text's composition history. Privacy and control: • Document text is read locally to compute content hashes; typing capture records timing and counts rather than key values. • Local evidence includes document URLs, titles, hashes and activity metadata. • With desktop integration, supported metadata is sent to the app on your own device. • Optional sign-in contacts WritersLogic authentication services. Firefox requests separate consent before account data is used. • Evidence is shared when you choose to export or share it. This extension contains no advertising or analytics SDK. A record can support an editor's review. It does not establish the origin of every word, prove that no AI was used, or establish that every observation is truthful. AI-tool copy events cover only interactions the extension can observe. Learn more: https://writerslogic.com Privacy: https://writerslogic.com/privacy
