Ai Text Assistant

100% Local and Private
All API keys, prompts, and settings remain on your device. Everything is stored in your browser, and nothing is transmitted to external servers. Your data stays entirely under your control.

This extension allows you to transform text on any webpage with the help of AI while keeping your information fully private and secure.
