Notes
Prep the board meeting.
Press a key. Talk. Juno types it.
It handles the pauses, restarts, and half-finished thoughts, then writes the line in the app you were already using. Nothing you say leaves your Mac.

Type the sentence you meant, not the one you said.
Juno keeps the thought and drops the filler, false starts, and take-backs.

Cleaner by default. Less fixing after you speak.
Numbers, dates, prices, and links land in the form you would type.

Ask for the edit in plain English. Juno rewrites the selected or recent text in place.

What is Juno?
Juno is the local voice layer for Mac. Press a shortcut, speak naturally, watch live words in the HUD, and Juno turns the thought into clean text in the app you were already using.
How is Juno different from other dictation and AI writing tools?
Juno ships the full Mac voice loop in one app: live HUD transcription, polished final dictation, Voice Actions, Voice Commands, per-app writing styles, and local vocabulary. It has no subscription or paid tier, no account, and no cloud dependency after setup. For the side-by-side view, see the voice tools comparison.
Does Juno work offline? Does my audio leave my Mac?
Yes. After the one-time local model download, everyday dictation and writing run on your Mac. Audio, transcripts, corrections, and local memory are not sent to a server or used for training.
Is Juno always listening? What is "Hey Juno" for?
No. You start Juno with the shortcut. "Hey Juno" is a phrase you say after starting a session when you want an Action, like making a note, reminder, or alarm, instead of inserting those words as text.
Does Juno work in every Mac app?
Yes, Juno is designed for normal Mac text fields across apps like Mail, Notes, Messages, Slack, browsers, docs, and AI prompts. If a secure field, remote desktop, or app blocks safe insertion, Juno shows Blocked or Copy Ready so you stay in control.
What can Juno do besides dictation?
Juno can rewrite selected or recent text, make it shorter, warmer, or more formal, turn it into bullets, translate it, learn vocabulary and snippets, and create Apple Notes, Reminders, and alarms. For the full list, open Juno and check Voice Commands in the app.
Where does Juno work best?
Juno is built for Apple Silicon Macs on macOS 14 or newer. 16 GB or more feels best for live transcription and local writing.
Is Juno a meeting recorder or meeting bot?
No. Juno is for active Mac writing and local actions. You can dictate meeting notes into Notes, Obsidian, or a document, but Juno is not a call bot, meeting recorder, or searchable meeting-memory product.
