Is Spell Checker for Chrome safe?

Low risk

Spell Checker for Chrome sends text you check to external spelling services.

When you run a spell check, the extension posts the text being checked to remote spelling endpoints for processing. Its source sends English and other supported-language text to newappzone.com or LanguageTool, and Korean text to nara-speller.co.kr.

Shared hosts - 2 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.
