FAQ
+Does it work in any app?
Yes — Erratly runs system-wide. Any text field, in any Mac app, once you’ve granted accessibility access.
+Does my text ever leave my Mac?
No. Corrections happen entirely on-device — nothing is sent anywhere.
+What if it fixes the wrong thing?
You can confirm or reject the correction.
+Does it work in languages other than English?
Yes — Many languages are supported.
+macOS says it can't verify the developer — what do I do?
Erratly isn't notarized by Apple yet, so macOS shows this warning on first launch. It's safe to open. See how to open it →
+Does Erratly need to download anything before I can use it?
Yes — on first launch, Erratly downloads its language model (~1.8 GB) once. After that it works fully offline. See what to expect →
