Sphere for macOS
The Mac assistant that learns you.
Talk to your Mac, type in any app or dictate anywhere, and Sphere gets it done. Every command, every dictation and every sentence you type teaches it a little more, so it gets better every day you use it. Most of it runs on your Mac, private and offline.
Free plan every day $9.99 once to remove the limits. Requires macOS 26 or later.
Say it. It's done.
Sphere learns you, runs on your Mac and works in every app. And it asks before anything risky.

Voice commands
Hold a shortcut. Say it. Let go.
Hold your shortcut, say what you want and let go. Sphere opens apps, arranges windows across your screens, plays music and searches the web. Those are instant commands, with no AI at all, so they happen right away.
Bigger asks go to the local model. It looks at your screen when you ask about it, and you can circle the exact thing you mean. Prefer typing? Type the same ask instead.
- "Code on my big screen, Chrome on the laptop."Arranges your windows across both displays.
- "What's wrong with this code?"Looks at your screen and answers in a line.
- "Reply to this. Thursday works."Drafts the reply at your cursor. It never sends.
- "Move my dentist appointment to 4."Shows the change and moves it when you approve.
- "Where do I turn on Night Shift?"Points at the exact spot on your screen.
- "When I say focus mode, close Slack and open my to-do list."Next time, two words do it all.
- Your phrasesPhrases you use often finish themselves. Ones you repeat are kept; one-offs fade after 30 days.
- Your style and your factsSuggestions sound like you. "I live in…" finishes with your city.
- What you acceptIn apps where you rarely take a suggestion, it holds back to the next few words.
- Your wordsFix a dictated word once and it's right from then on.
- Your routinesAsk once and it works out the steps. Ask again and it's instant.
- YouYour city, workplace, projects and favorite apps, suggested for you to keep or dismiss.
It learns you
Nothing to train. Just use it.
Every command you give, every word you dictate and every sentence you type teaches Sphere something. Write Ahead and dictation fixes catch on almost right away. Facts about you come in batches, as suggestions you keep or dismiss, and a dismissed fact never comes back.
It all stays on your Mac, and you can see and erase every bit of it. Each kind of learning has its own switch. Sphere never learns health, money or passwords, and never learns from text on your screen.
Everything Sphere does
One assistant for your voice, your typing and your screen.

For email, Slack and anyone who types a lot.

- 16 GB Macs Gemma 4 E4B
- 32 GB Macs Qwen 3.6 35B, stronger on long tasks
- Claude Optional

Questions
How much does Sphere cost?
Sphere has a free plan you can use every day: 25 voice commands, 25 dictations, 100 accepted Write Ahead words and 25 minutes of Read Aloud. A license is $9.99, paid once, and removes every limit. There is no subscription.
Does Sphere send my data anywhere?
Not by default. A local AI model does the work on your Mac, and your voice is turned into text on your Mac. What Sphere learns stays on your Mac, and you can see and erase all of it. If you choose to connect Claude, only the asks too complex for the local model go to Claude.
Do I need Claude or an API key?
No. Sphere works with no API key and no account. Claude is optional, for requests too complex for the local model. Background agents and routines currently need Claude Code with a Claude Pro or Max plan.
How fast does it learn?
Write Ahead and dictation fixes catch on almost right away. Commands you repeat get faster the second time. Facts about you arrive as suggestions in batches, and you keep or dismiss each one.
What will it never learn?
Sphere never learns health, money or passwords, and never learns from text on your screen. Each kind of learning has its own switch in Settings.
Which Macs does it run on?
Sphere needs macOS 26 or later. It uses Gemma 4 E4B on 16 GB Macs, or Qwen 3.6 35B on 32 GB Macs for stronger long tasks. It installs with one line, is signed and notarized, and updates itself.
