Scusi
Scusi is a Mac utility for transcribing iMessage voice notes and adjusting playback speed so audio messages are easier to review.
What is Scusi?
Scusi is a macOS utility that helps you read and manage iMessage voice notes more comfortably. It lets you drag an audio message from Messages into the app to generate a transcription, and it also adds playback speed controls for listening more quickly or more slowly. The app is useful for people who receive long voice messages, work in quiet or shared spaces, or prefer reading over audio playback. Scusi supports multiple languages and remembers the selected language for each conversation, which makes repeated use more convenient. Audio transcription is performed on the Mac itself rather than being sent out for processing, which fits privacy-conscious workflows. Scusi was created by Jordi Bruin together with Hidde van der Ploeg as a focused communication helper for Mac users.

Safety overview
Status: Mostly safe
Scusi is a legitimate Mac utility for working with iMessage voice notes. Its audio transcription is designed to run locally on the Mac, which reduces the need to send message audio to external services for this feature. If you use it, treat it as a helper for message content and avoid dropping sensitive audio into any app unless you are comfortable with that access. Because the app has not been updated for a long time, users on newer macOS versions may run into compatibility issues or unreliable behavior.
Recommendation: Keep Scusi if you actively use it to read or speed through iMessage voice notes on your Mac. If it no longer fits your workflow or does not run well on your current macOS version, you can remove it without affecting core macOS features beyond losing its transcription and playback conveniences.
