Is Wordtune: AI Writing, Paraphrasing & Grammar Tool safe?

Medium risk

Wordtune sends readable page HTML, URL, and title from selected sites to its insights API.

When Wordtune's remote configuration enables its insights feature for a site, its content script monitors the page and checks whether the page is readable. It then sends the page URL, title, raw HTML, and readability-parsed HTML to Wordtune's insights endpoint along with a device identifier.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 9 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
