Spelr is a Windows-based software providing intelligent spell checking utility for multiple languages that can be used with any program. It offers three options to spell check, including clipboard, selected text, or entire documents.

By default, spelr comes with the U.S. English dictionary, but it's Mozilla dictionaries-compatible. Hence, you can install multiple dictionaries to fit your language preferences. Not only is this software robust, but it is also user-friendly. With spelr, you can be sure that it sits quietly in your system tray, always ready for use.
Some of its best features include its learning mechanism that corrects misspelled words according to your behavior. It also has a user dictionary that allows you to have a personalized list of words. Additionally, you can install different dictionaries for various languages, and with its user-configurable hotkeys, you can spell-check efficiently.
Spelr also grants you quick access to an online dictionary and thesaurus to help you with the meanings and synonyms of words. If you ever need it to work at every startup or launch of your computer, it has an option to start itself when Windows starts. Best of all, it is crap-free, with no adware, spyware, or malware.
