The problem

The answer always comes five minutes too late.

On live calls there's no time to think, search, or scroll your notes. You freeze on the hard question, blank on the name, or miss the follow-up — and you're stuck taking notes instead of actually listening.

You freeze on the hard question

The curveball lands and your mind goes blank. By the time it comes back, the moment's gone.

You're typing instead of listening

Scrambling for notes and context means you miss what's actually being said.

Existing tools are obvious

Bots that join the call or pop up on screen share announce that you're getting help.

The solution

A copilot only you can see.

Sotto lives in your menu bar and quietly transcribes the conversation. Press ⌘⏎ and it gives you a sharp, context-aware answer in seconds — on a floating overlay that stays invisible to screen recording and screen share.

  • Real-time transcription, running on your Mac — no bot joins the call
  • Press ⌘⏎ for an instant, context-aware suggested answer
  • Remembers the whole conversation — not just the last line — for answers that stay on-thread
  • Custom Modes feed it your résumé, deal notes, or docs for tailored replies
  • Tap ⌘\ to hide the whole thing in a blink

Privacy & undetectability

Invisible by design. Private by default.

Sotto was built so the help stays yours alone. Transcription happens on your Mac, and the overlay is engineered to stay out of every screen share and recording.

  1. 1

    Transcription runs on-device

    Speech is converted to text locally with WhisperKit on Apple Silicon. Your raw audio never leaves your Mac.

  2. 2

    Hidden from screen capture

    The overlay panel is excluded from screen recording and share, so it doesn't appear in Zoom, Meet, Teams, or QuickTime.

  3. 3

    You bring your own AI key

    Answers use your own OpenAI API key, stored securely in your macOS Keychain. You stay in control of your data and spend.

FAQ

Questions, answered.

What is Sotto?

Sotto is a macOS app that runs as an invisible overlay during your calls. It transcribes the conversation on your Mac in real time and, when you press ⌘⏎, gives you a context-aware answer you can use right away.

Is it really invisible on screen share?

Yes. The overlay panel is marked as non-capturable, so it's excluded from screen recording and screen-share tools like Zoom, Google Meet, Microsoft Teams, and QuickTime. You can also hide it instantly with ⌘\.

Does my audio leave my Mac?

Transcription runs on-device with WhisperKit, so your microphone audio is processed locally and isn't uploaded. When you request an answer, the relevant transcript text is sent to your chosen AI provider to generate the response.

Do I need an API key?

Yes — Sotto uses your own AI provider key (e.g. OpenAI) to generate answers. It's stored securely in your macOS Keychain, so you keep control of your account and spend.

Which Macs are supported?

Sotto is built for Apple Silicon Macs running a recent version of macOS.

What are the main hotkeys?

⌘⏎ asks for an answer from the live conversation, ⌘\ toggles the overlay's visibility, and ⌘R starts a fresh session.

Is this allowed?

Sotto is a productivity tool. Use it responsibly and in line with your employer's, school's, and platform's policies, and any laws that apply to recording or assistance in your situation.

How long does setup take?

A couple of minutes: download, grant microphone access, paste your API key, pick a Mode, and you're ready for your next call.

Never get caught off guard again.

Download Sotto free and walk into your next call with an invisible copilot in your corner.
