Jarvis. A voice assistant that lives on your computer.
Say "Hey Jarvis" and ask. He opens apps, plays music, sets reminders, takes notes, reads you the page you are on and answers questions. The wake word, speech recognition and voice all run on your machine, so your audio never leaves it.
Free to download. No account needed.

What he does
Runs your computer by voice
Open apps, folders and websites, control music and volume, lock the screen, take screenshots.
Remembers for you
Reminders, notes to self and routines like "work mode" that open everything you need at once.
Knows what you are looking at
Summarise this page, explain the selected text, read it out loud.
Answers anything else
Connect an AI brain and he answers open questions, with live facts from the web.
You choose what he connects to
Jarvis installs with every add-on switched off. Turn on only what you want from his Integrations page: an AI brain, Google Calendar and Gmail, YouTube and Analytics stats, Telegram on your phone, Fireflies meeting notes and more. Each one uses your own key, stored only on your computer. The installer never asks for passwords or accounts.
Private by default
Listening, speech recognition, the built-in commands and his voice all run locally. Only questions the built-in commands cannot answer go out as text, and only to the AI service you switch on.
