Fixkey is a tool designed primarily for macOS users, geared towards amending grammar within any application. This mechanism uses advanced artificial intelligence to primarily detect and correct any typographical errors, thereby aiming to enhance the quality of writing.

In addition, it allows users to insert custom prompts at any time, adding versatility and personalisation. With a single keystroke, users can rectify the grammar of a line or even an entire paragraph.

Moreover, the tool offers fully customizable shortcuts to activate its functions. It is also written natively for macOS, promising lightweight, efficient performance.
