Select text, press a hotkey, pick a preset. BrushUp rewrites your English to sound natural, correct, or professional — right inside Outlook, Slack, Word, or whatever you're typing in. The built-in provider works instantly: no account, no API key, no setup.
No copy-paste. No tab-switching. The popup floats above your work and disappears the moment you're done.
Highlight a sentence, paragraph, or whole draft in any application — email, chat, document, or browser.
Press Ctrl+C, then tap C once more within half a second. A floating popup snaps open with your captured text. The second letter is configurable.
Choose Fix Grammar, Make Formal, Lookup — anything. Hit Enter to rewrite, Enter again to replace the text right where it was.
Designed for non-native English speakers who type all day. Mouse-free, account-free, and entirely under your control.
UI Automation captures text from any app — Outlook, Word, Slack, Notion, browsers, even legacy apps. Clipboard fallback included.
The built-in provider works the moment you install — no account, no API key, no model picking. A 14-day free trial starts automatically.
Watch the improved text arrive word by word. Cancel anytime if the rewrite goes sideways.
See exactly what changed. Deletions struck through, additions highlighted. No mystery rewrites.
Select any word and hit Lookup: definitions, IPA pronunciation, example sentences, a memory aid to make it stick — and a speaker button to hear it aloud.
Every rewrite and lookup is saved on your machine — review past results, spot your patterns, and memorize new words. Nothing leaves your PC.
A phosphor-on-black dark theme and a warm paper light theme, across the popup, settings, and learn. Follows Windows by default — just like this page.
Replaced the wrong thing? One click restores the original text in the source app — instantly.
Stay on the home row. Tap a number or step through presets with ← →, press ↵ to rewrite or replace, and Esc to dismiss — your hands never leave the keyboard.
Signed releases update themselves in the background — you always run the latest version without hunting for a new installer.
Seven rewrite presets with carefully tuned prompts — edit them, add your own, or delete what you don't use — plus the built-in Lookup dictionary.

Download the app and start your trial. When you're ready, click Buy inside the app — checkout takes a minute and your license activates automatically. No keys to paste.
Yes. The license follows your account, not your machine — sign in on a new PC and you're set. One active machine at a time.
