Key Filler is a free Chrome extension developed by Eric Ren. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This handy tool automatically fills input text fields with preset data, specifically targeting fields with the custom id "#key".

With Key Filler, you no longer need to manually type in the same information repeatedly. Whether you are filling out forms, entering login credentials, or providing other input data, this extension saves you time and effort by automatically populating the designated text fields.

The simplicity of Key Filler makes it an efficient tool for users who frequently encounter input text fields requiring the same data. By eliminating the need for manual input, it streamlines the process and enhances productivity.

Note: Key Filler currently supports filling input text fields with the custom id "#key" only, limiting its functionality to specific scenarios.
