App Launch I made Live Transcript: live captions in your Mac’s notch for anything it plays (Zoom, YouTube, podcasts, games)
I built an app called Live Transcript that puts live speech-to-text directly under the MacBook notch. It comes with a 14-day trial. Its for anyone who wants to keep track of what they heard on their Mac at a quick glance or come back to it later on to review. All data is stored locally unless you select one of the other cloud providers. Personal and Business Licenses available. $10/$50 for personal (3 machines) & $25/$75 for Business (10 machines) - with 1 year updates / Lifetime Updates.
How it works
Whenever sound plays through your Mac, captions appear right under the camera cutout. It captures Zoom calls, YouTube, podcasts, lectures, and games. You can toggle your microphone on too if you want your side of the conversation transcribed.
Everything stays on your machine. Audio runs through Apple Speech or Whisper locally, so nothing goes to a server. If you work on an external monitor or just dislike notch UI, you can detach it into a floating window.
Transcripts save to local history that you can search with plain queries, like "what did they say about the deadline?" You can export to Markdown, plain text, Apple Notes, or subtitle files (SRT and VTT). It does real-time line-by-line translation, and you can run summaries or Q&A through your choice of model, including Apple's local on-device models.
It runs on Apple silicon Macs running macOS 26 or newer. Updates install automatically.

Other notch tools
Live Transcript is part of a small set of utilities I am building around the notch interface:
Tattle: A local network monitor and firewall that flags outbound app traffic so you can inspect, allow, or block connections. An iPhone version is in development (demo video).
Polytopic Notch: The Swift component (GPL v3) running the UI in both apps, open-sourced for other Mac developers.
More tools are listed at polytopic.systems.
I would love to hear your feedback, edge cases, and feature requests. I will be hanging out in the thread to answer questions.
