About this product
Private Writing Assistant checks text inside Chrome fields, including email drafts and Google Docs. Click an underlined word to inspect a correction, or select a paragraph to rewrite it in a different tone or length. The developer lists support for 101 languages, with sentence-level detection for mixed-language text.
Checking and rewriting use Chrome’s built-in AI on your device. They can work offline once Chrome downloads the model. The developer says that typed text stays local and separately discloses usage telemetry, including site names and the extension version.
The extension is free. Before installing it for an entire team, check whether each desktop can run Chrome’s built-in model. Browser version, storage, and memory determine whether the feature is available.
Features
- On-device grammar and spelling checks
- Rewrites for selected sentences and paragraphs
- Sentence-level language detection
- Offline checking after the model downloads
