Frequently asked questions.

Quick answers about safety, privacy, and how the extension works.

Are Chrome extensions safe?

Walter processes text when you invoke a tool from the extension. Review the current privacy policy for details about submitted text and account data.

Does the extension work offline?

The extension requires an internet connection for Walter processing features. Availability can also depend on the page and browser permissions.

Can my employer block it?

Yes. Like any extension, an organization can block or allowlist Walter through managed Chrome policies. If it’s blocked on your work profile, it still works on a personal Chrome profile.

Does it work in Incognito?

Only if you turn it on. Chrome disables extensions in Incognito by default; you can enable Walter at chrome://extensions. It works the same way there and still only sends text when you invoke it.

Humanize & Detect AI anywhere you type.

Highlight any text to humanize AI drafts or check if it is AI, right inside Gmail, Docs, LinkedIn, Notion, Slack, ChatGPT, and Claude.
