What Is Tiny Spell?
Tiny Spell is a small Windows utility designed to provide spell checking functionality across applications that do not include their own built-in spell checker. Unlike traditional spell checkers that only work inside word processors, it runs entirely in the background and monitors your typing system wide.
When a misspelled word is detected, the tool alerts you immediately, allowing you to correct mistakes as you type. This makes it especially useful for writing emails, forum posts, chat messages, code comments, or text entered into older or lightweight applications.

- System-Wide Spell Checking: Works with nearly any Windows application, including browsers, text editors, email clients, and chat programs.
