Networked live teleprompter for broadcast.
Notse separates the talent-facing prompter from the slide-driving graphics rig — mirroring how pro broadcast workflows already operate. A Mac runs the prompter; a Windows helper drives PowerPoint via Microsoft COM in real time. Networked over LAN, no cloud round-trip.
How it works
A two-machine system. One drives the slides, the other shows the prompter.
Graphics machine (Windows)
Runs PowerPoint and a small Notse Helper service. The helper polls PowerPoint via Microsoft COM at high frequency, tracking slide position and click-triggered build animations. State changes push to the Mac instantly.
Operator machine (Mac)
Runs Notse.app — the formatted prompter window the talent or operator reads from. Edits in the prompter (Cmd+E) write back to the PowerPoint file via COM, so prompter content and slide notes stay in sync. Arrow keys remote-control slides on the graphics machine.
The two communicate over LAN via WebSocket on a configurable port (default 9816).
What it does today
v0.5.12 — May 2026
Live PowerPoint integration
The Windows helper polls PowerPoint via Microsoft COM and pushes slide-position and build-state changes to the Mac in real time.
Bidirectional note editing
Cmd+E writes prompter edits back to the PowerPoint file via COM. Keep prompter content and slide notes in sync without leaving the prompter.
Build-aware rendering
When slides have click-triggered animations, Notse shows build indicators so the operator knows exactly when to advance.
Slide control from the Mac
Arrow keys advance/reverse slides on the graphics machine. Cmd+B toggles slideshow, s opens jump-to-slide picker, Cmd+O opens the slide list panel.
Pre-cached notes
All slide notes are fetched when the slideshow starts, so jumping around feels instant — even with hundreds of slides.
Dynamic prompter formatting
Tick mark customization, bullet formatting, alternating row colors, live-resizable build indicators.
macOS code-signed and notarized
Apple Developer ID signed, notarized, stapled. Download, mount, drag to Applications, launch — no Gatekeeper friction. In-app updater for new versions.
License + diagnostics built in
Keygen.sh-backed activation with offline expiry and 3-machine fingerprinting. One-shot field-log push (Mac and Windows) for remote diagnosis.
Coming soon
Active development — these aren't shipped yet.
Windows code signing In progress
Eliminates SmartScreen friction for the Windows helper installer. Imminent.
NDI output Coming
Clean teleprompter feed broadcast over the network for ingest into video switchers (OBS, vMix, broadcast production setups). The headline pro broadcast feature.
Solo Mode Coming
Read scripts from local files (.md, .txt, .docx) or Google Docs — no slideshow required. For solo presenters, podcasters, and security-conscious customers.
PowerPoint Mac helper Coming
AppleScript-based helper to unblock Mac-only show rigs — no Windows machine required. Keynote and Google Slides helpers planned next.
Primary/backup with auto-failover Coming
Source-switching with automatic failover for high-stakes broadcast. Redundancy that matches the rest of your show rig.
Audio auto-follow Coming
Speech-to-text tracking that scrolls the prompter to match what the speaker has said. Hands-off operation for solo presenters.
System requirements
Operator (Mac)
macOS 12+ on Apple Silicon or Intel. Notse.app runs the prompter window.
Graphics (Windows)
Windows 10 or 11 with PowerPoint. Notse Helper service drives slide tracking via COM. Mac graphics-machine support is in development.
Network
Both machines on the same LAN. WebSocket on configurable port (default 9816). No cloud account, no browser.

Built from inside the workflow
Jason Vaughan is a working technical director and graphics operator in live event production. Notse is built from inside the workflow it serves — designed by someone who runs the show, not just builds for it.
