Is FlyMSG: AI Writer, Autofill Text Expander & Grammar Checker safe?

Low risk

FlyMSG sends text from editable fields to WebSpellChecker for grammar, autocorrect, and autocomplete checks.

When you are signed in, FlyMSG initializes WebSpellChecker on editable page fields and sends typed text, sentences, or tokens to svc.webspellchecker.net/api for checking. The extension uses this service for grammar checking, autocorrect, and autocomplete on matched webpages.

Shared hosts - 4 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.

Where it sends data

Destinations our analysis observed FlyMSG AI contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • svc.webspellchecker.net

    FlyMSG AI sends data to svc.webspellchecker.net. No other extension we have analysed sends data here.
