Elevate your writing instantly. For clear communication, try Fleschkey, the go-to tool for real-time readability analysis using the Flesch-Kincaid tests. Have you ever tried to generate text with AI or rewrite text with AI? If yes, then you know that it is not that great. Either it makes your text gibberish or it throws you the same text you wrote before. It is not that great. That's why instead of using AI, we use a different approach. We use hard-coded rules and tests to help you with your writing. Thanks to that, you learn how to create unique text on your own and get insights into what makes great text great. Unlike other web text editors, Fleschkey does not send your writing data to the cloud. Everything you create stays on your device, securely saved locally.
