Zack KI

The AI comes to you, not the other way round.

What is Zack KI?

Zack KI puts AI one keystroke away. Select text or files in a supported Windows app, press Alt+1, and ask. PDF, Word and Excel files can be attached from Explorer, and answers can be written back into selected text. The 2.x update adds direct text actions: Alt+3 to improve wording and Alt+4 for spelling and grammar. Chats are stored on your PC; online requests go to model providers. Windows only. Free to try: 500 starter credits, then 100 per week, no card needed.
