What Korr is
Korr is a spelling and grammar checker that analyzes text and suggests corrections, with style suggestions also available. Its website and browser extension handle French, English, Spanish, Italian, and Portuguese; the Windows app supports French and English. The extension works in Gmail, Slack, and text fields generally, while the site also names Outlook and LinkedIn. In Windows programs such as Word, Outlook, and Discord, users can select text and press Ctrl+Alt+C to check it. Text is processed in the browser or on the computer rather than sent to a correction server. Korr displays each change in its sentence and lets users reject changes individually. A personal dictionary stores words on the device and is not synchronized or transmitted. Korr is free, with no account, subscription, usage limit, or paid tier. It is licensed for personal or professional use, and is available as a website, browser extension, and Windows app. Support is available by email in French and English, usually within two working days.
