What is new in Nogrammerly 1.3.0

## What's new

- **Right-click rewrite.** Select text in any app, right-click it and choose **✦ Rewrite…**. Pick a style (Professional, Friendly, Confident or Concise), preview the result, then choose **Accept**, **Copy**, **Reject** or **Retry**. **Show <App> Menu** brings back the app's own right-click menu.
- **Every rewrite is previewed.** The rewrite actions in the corner button and the menu bar now show the result before changing your text.
- **Launch at Login.** Turn it on from the ✦ menu-bar menu or the Nogrammerly menu.

## Fixes

- Everywhere mode didn't start when macOS reopened Nogrammerly after a restart, because the system spell checker wasn't ready yet. It now starts reliably.

Apple silicon (arm64). Open the DMG and drag Nogrammerly to Applications.
