Introducing Sussurro - Your On-Device Copilot, Powered by MLX

Introductory Article
Listen. Understand. Act. All without leaving your Mac.

We started Sussurro with a simple belief: the words we speak at work are our single most valuable data set - and they deserve the same super-powers we already give to text and code. Yet today, turning spoken ideas into something searchable, actionable, and shareable still feels like homework.

So we built the tool we always wished existed: a private, on-device meeting copilot that turns every conversation into instant insight - no cloud required.


Why On-Device Matters

  1. Privacy by architecture - Audio never leaves your machine. Your NDA moments stay yours.
  2. Zero-lag experience - Running locally means sub-second transcription and summaries. Hit Leave Meeting and your notes are already waiting.
  3. Works anywhere - Airplane Wi-Fi? Corporate firewall? Sussurro keeps humming because it doesn't phone home.

The MLX Edge

Apple Silicon's Neural Engine is a marvel - if you can speak its language. MLX, Apple's open-source tensor library, lets us squeeze every FLOP out of those cores while keeping batteries happy.

  • Whisper-grade transcription: Fine-tuned to stream live audio at 1× real-time.
  • Local LLM: Ask follow-up questions, generate summaries, or search past calls - all powered by an MLX-optimized model living right beside your Photos library.
  • Tiny footprint: MLX binaries measure in megabytes, not gigabytes, so Sussurro feels at home on a base-model MacBook Air.

What Sussurro Does Today

  • Live Transcription: Accurate, speaker-aware captions as the meeting unfolds.
  • Instant Summaries: Key decisions, action items, and blockers the moment the call ends.
  • Chat With Your Meetings: “What did Sarah promise about the API timeline?” - answered in one line.
  • Automatic Organization: Recordings and notes neatly filed by project and participant.

And because everything lives on your Mac, you can unplug from the internet the second the Zoom tab closes.


Where We're Headed

Our roadmap is outrageously ambitious:

  1. Real-Time Translation - Bridge language gaps on the fly.
  2. Calendar Awareness - Prep materials before you even join the meeting.
  3. Cross-App Commands - Turn verbal “Add this to Jira” into, well, an actual Jira ticket.

If you're as excited as we are about local AI, we'd love your feedback to shape what comes next.


Join the Early Access Crew

Sussurro is currently in private beta for Apple Silicon Macs running macOS 14 or later. We're onboarding users in waves to ensure buttery performance for everyone.

We read every submission. Seriously.


The era of local AI has arrived - let's make every word count.
