Meet Nixi.
A free voice assistant for Windows. It lives at the top of your screen and does what you say: opens apps, sets timers and reminders, keeps your to-do list, finds your files, dictates into any app, writes first drafts and answers questions about your screen. Speech recognition and the AI run entirely on your PC.
Requirements: 64-bit Windows 10 or 11, a microphone and about 2.5 GB of disk space. 8 GB of memory is recommended; a graphics card is optional.
