Reporting a wrong correction
This is the most useful message you can send us. Korr is built on one rule: damaging a correct sentence is worse than missing a mistake. Every report of a wrong correction becomes a permanent test.
To let us reproduce it, please include:
- the sentence exactly as you typed it;
- what Korr turned it into;
- what you expected instead;
- the language, and whether you used the website, the Windows app or the browser extension.
Your text is never sent to us automatically. Nothing leaves your device unless you copy it into an email yourself.
Frequent questions
Where is my text processed?
On your device, always. Korr has no analysis server: there is nowhere for your text to be sent. You can check it yourself by cutting your connection after the first load, the correction keeps working.
Is Korr free?
Yes, entirely. No account, no subscription, no usage limit and no feature held back behind a paid tier.
Why was a correct sentence changed?
It should not have been, and we treat it as a bug. Send us the sentence and it becomes a test case, so that the mistake cannot come back.
Why is a mistake not corrected?
Some sentences are genuinely ambiguous, and when Korr cannot decide it prefers to leave your text alone. Tell us which sentence, and we will see whether the case can be settled safely.
How do I remove Korr?
The web app is uninstalled like any installed website, from your browser. The Windows app is removed from Settings, Apps. The extension is removed from your browser's extensions page. Nothing is left behind on a server, because nothing was ever stored on one.
Do you keep my personal dictionary?
It stays in your browser, on this device. It is never synchronised and never transmitted. Clearing your browsing data erases it.
