Enlace Assistant offers a collection of helpful tools that run entirely locally, providing users with a range of features including optional encryption. The program includes various tools such as additional clipboard paste-bins, a pass phrase generator, snippets storage, page notes, HTML and regex testers, and more.

Within the popup tools, users can leverage features like the Clipboard tool, which allows setting and copying values using custom keyboard shortcuts, all encrypted by default. The Pass Phrase Generator offers customizable passphrases in diverse formats, while the Snippets tool enables the storage of key/value pairs for easy access and search, useful for commonly used text snippets. Users can also manage cookies efficiently with a basic view and editor, facilitating the deletion of all cookies for a specific site.

In addition to the popup tools, Enlace Assistant provides sidebar tools like Page Notes, allowing users to save private notes linked to specific URLs using configurable regex patterns, ensuring easy reference on subsequent visits. The program also includes options for HTML Sandbox, enabling live previews of HTML/CSS input, along with Regex Tester and Regex Find and Replace functionalities for regex pattern testing and text manipulation.
