## Overview

SpellFast AI takes a deliberately different approach from most writing assistants: rather than highlighting every possible issue with underlines and tooltips as you type, it stays silent until you ask for help. Press CTRL + SHIFT + I and the extension rewrites the text you are working on, in place, wherever you happen to be typing.

That shortcut-first design works across virtually any website, from webmail clients and Google Docs to social media comment boxes and support ticketing systems. A hands-free mode adds voice commands so you can trigger corrections without touching the keyboard, and the extension advertises multilingual support for polishing text that is not in English.

The extension is privacy-focused in its positioning: the developer states that your writing is not collected or stored. It offers in-app purchases for paid capability, and a support contact is provided by the publisher. Because it is a small independent tool, feature depth is intentionally narrow compared with full writing platforms.

## Pricing & Plans

Free to install with optional in-app purchases for paid features. The listing does not publish exact paid tier prices.
