Is Read Frog - Translate & Learn safe?

Clean risk

Read Frog sends selected or page text and optional page context to AI translation backends when you ask it to translate.

When you invoke translation or enable auto-translate, Read Frog collects selected text or page paragraphs plus optional page title, description, content, or summary context. The background worker queues that text with language and provider settings and sends it to Read Frog's hosted AI API or a provider you configured.

Shared hosts - 5 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.
