Portable spelr

Reputable text editors come with built-in spell checking options, but if yours doesn't, you might want to consider trying an external tool to find typos and make sure your documents are error-free.
Portable spelr is a simple, yet handy software utility that can add spell checking capabilities to any application, also providing options to assess the status of the clipboard content or a simple text selection.

Spell check documents and the clipboard

No installation is required and the application is placed in the system tray upon launch, so as not to interfere with your work. It waits for you to press one of the hotkeys to spell check opened documents or a simple paragraph you selected.
Moreover, you can even assess the status of your clipboard, even if its content is not yet pasted in any document or window. Once you are sure the text has no typos, you can easily paste it.

Personal dictionary and auto-correct options

Portable spelr detects and shows all errors one by one, providing suggestions and enabling you to replace typos with the correct word with just a click. You also have the option to simply ignore the mistake or add the detected word to the personal dictionary, which automatically instructs the application to consider it as correctly typed from that point on.
Portable spelr comes with a collection of word pairs (the first is misspelled and the second is the correct form) that include common spelling mistakes, which are automatically identified and corrected. You can manually add new words to improve its accuracy.

Multi-language spell checker

By default, the dictionary Portable spelr uses is the American English one, but you can easily change it from the 'Settings' area. What is great is that the options are not limited to the installed dictionaries, as you can also set up a new dictionary yourself, choosing from the dictionaries and language packs offered by Mozilla.
Overall, Portable spelr is a handy tool to anyone, quickly checking any document for typos and also providing one-click access to online dictionaries and thesaurus. With its help, you can make sure your documents are error-free without a lot of hassle.
