A local conversation memory app that records and transcribes meetings on your device, then exposes them to MCP clients as Markdown files you own.
Minutes records and transcribes meetings, calls, voice memos, and dictation on your own machine, then lets Claude Code, Codex, Cursor, or any other MCP client search the history you choose to share. Meeting context stops living inside a vendor's workspace and starts living in files you can grep.
Capture, transcription, and storage all run locally. Each meeting is a plain Markdown file in a meetings directory in your home folder, carrying structured YAML frontmatter with the title, date, duration, action items and their assignees, and the decisions taken. Text leaves the machine only when you send authorized context to a cloud agent or summarizer.
Five surfaces read those same local files.
- Desktop app: menu bar capture along with Recall, documents, and Coach.
- CLI: 58 commands for recording, processing, search, import, and automation.
- MCP server: 34 local meeting tools and resources for any MCP client.
- Claude Code plugin: 23 skills covering prep, capture, live help, debrief, and memory workflows.
- SDK: TypeScript access to the meeting files without going through MCP.
Install through a Homebrew cask, a Homebrew formula, cargo for the CLI, or npx for the MCP server, and a demo command seeds five sample meetings so the search can be tried with no microphone. Sensitive meetings save typed markers without audio and default to restricted, with consent reminders and provenance to help you disclose recording. It is MIT licensed, with no paid tier for anything in the repository.
Desktop meeting notes with transcription that runs on your own machine, for people who want a record without sending audio away.
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.
