Is MetaGramm grammar checker safe?

Low risk

MetaGramm replaces the new tab with a grammar editor and search box that send your text to its own servers.

Text typed into the new-tab grammar editor is sent as HTML to apis.metagramm.ai for checking when you click the check button. Queries typed into the new-tab search box are posted to extension.metagramm.ai before being passed on to Yahoo. The extension declares no permissions and runs no content scripts, so this only applies to what you type on its own new-tab page.

Shared hosts - 1 hostname

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.
