Fuzbal is a free Chrome add-on developed by ilch. It provides a convenient way to perform fuzzy search and regular expression matches while using the Ctrl+F function. With Fuzbal, users can find non-exact results by allowing for potential misspellings and searching for words that are often seen together in context.

This add-on utilizes string edit distance for fuzzy search and Stanford's GloVe pre-trained word vectors for searching by regular expressions. The dictionary file is included with the extension, enabling all searches to be performed locally. Fuzbal enhances the search capabilities of the Chrome browser, making it easier to find relevant information even when exact matches are not available.
