Prismical

Prismical Desktop is a meeting notes app for macOS and Windows. Recording, live transcription and a rich text editor sit in the same window, and the first launch asks the question that matters most, which is whether any of it leaves the machine at all.

It is an Electron app built with React and Effect, rendering the same screens over the same data layer as the Prismical web app, with platform differences routed through a ports seam. In local mode the notes live in a SQLite file, transcription runs on device with whisper.cpp using Metal on Apple silicon, and meeting detection simply watches which application is holding the microphone.

The two modes and the pieces around them break down as follows.

• Local mode: no account, notes stored locally, and nothing leaving the machine unless you configure a provider.
• Cloud mode: signing in adds sync across devices, sharing, organizations, calendar, managed models and true speaker diarization.
• AI skills: Enhance, Cleanup, Name note, Ask and custom skills run against a key you bring or a local runtime such as Ollama.
• Installers: every release attaches a macOS disk image and a Windows installer, and packaged builds update themselves.
• Native helpers: audio capture, microphone detection and calendar access are separate Swift and C# packages.

Switching modes resets local data, as there is no migration between the two. The app is MIT licensed, and building from source needs Node 24, pnpm, CMake and the platform toolchains, plus the whisper.cpp submodule so the transcription addon compiles.
