Does Dokio have a spell-checker function?
Because Dokio is a browser-based application, we rely on the spellcheck features built natively into your internet browser to perform that task. We recommend ensuring your browser's spellcheck feature is turned on and set to check for errors 'as you type'.
Alternatively, there are other specialised third-party plugin applications like Grammarly, which can be downloaded and installed to your browser for free to manage spelling and grammar across your browser and system.
Enabling spell checking in your browser
Below are some helpful articles on enabling spellchecking in your browser that were current at the time of writing. We do recommend checking your browser's Help section for more up-to-date information on how to do this.
