A personal AI that lives on your Mac, not in the cloud.
ONX Assistant fuses a local AI, voice, calendar, knowledge base and a remote-control bridge into a single desktop app. Everything runs from the app itself. No cloud dependency for the core.
Six pillars, one app.
Local-first agent
Runs on your Mac with automatic warmup, self-healing, and streaming replies. Works fully offline when you need it.
Voice-native
Always-on wake word, local speech to text, and natural voice replies that start speaking before the answer finishes.
Calendar and reminders
Full events with categories, colours, and repeats. Import from Google or Apple. Reminders stay in sync.
Telegram remote
Chat with your Mac from anywhere. Send files up to 50 MB. Custom commands. Works even with the lid closed.
Shortcuts and macros
Verbal shortcuts, a quick launch bar, and a safe-mode bridge. Opt into more power when you're ready.
Lid-close reliable
Stays awake in the background so reminders, voice, and remote replies keep flowing.
How it works
- Install once. One click installs it and sets it to start with your Mac.
- Set your auth key. Binds your licence to your machine. Survives reinstalls.
- Pick a voice. Voice packs install with one click, or use native macOS voices.
- Live your life. Speak, type, or message it. ONX handles the rest.
Built for trust
- Your knowledge stays local. Nothing leaves unless you ask.
- Lock screen with password pause and resume.
- Private mode blocks outbound requests entirely.
- Clean uninstall removes every stored flag and permission.
