Aspell

As a software tool, Aspell offers a spell-checking feature that can be utilized either as a stand-alone application or as a library. Its greatest strength lies in its superior capability to suggest possible replacements for a misspelled word. In fact, it outperforms most of the spell checkers available for the English language.

Another remarkable aspect of Aspell is its compatibility with UTF-8 encoding – it can easily check documents without the need for a special dictionary. Additionally, Aspell can adjust to match the current locale setting, taking into account regional variations in spelling and grammar.

One of the things that sets Aspell apart from its competitor, Ispell, is its support for multiple dictionaries simultaneously. This feature comes in especially handy when handling multiple Aspell processes simultaneously. Aspell also manages personal dictionaries intelligently, making it a more efficient and user-friendly spell-checking tool.
