On device private AI meeting transcripts
Synopsule is an on-device private AI meeting transcript tool for Mac and iPhone that captures conversations, transcribes them locally using Whisper, and labels every speaker. Its core value is privacy: your audio never leaves your device, and you get a clean, searchable transcript with replayable audio. Designed for professionals who need accurate notes without compromising data security, Synopsule works completely offline from the first launch and requires no account or subscription for its core features. The $1.99 one-time purchase covers both Mac and iPhone, making it a budget-friendly alternative to cloud-based meeting tools that charge monthly per-seat fees.
Cloud notetakers typically upload your audio to their servers for processing, require an account, and often discard the raw audio after transcription. Users worry about their sensitive conversations being stored on third-party servers, while many tools also fail to distinguish speakers or lock notes in proprietary formats. Synopsule solves all these problems by performing every step on your device: audio capture, transcription, speaker diarization, and even AI summaries when you opt in. This design ensures that your meeting data remains completely private, and you own the resulting notes in open formats like Markdown that any AI agent can read.
The first major feature is on-device Whisper transcription. A Whisper model ships inside the app, so it works immediately without any internet connection or downloads. For higher accuracy, you can download larger models up to 1.5 GB and switch between them instantly with no redownload. This flexibility lets you balance speed and precision depending on the recording environment, whether you need real-time transcription in a quiet room or maximum accuracy in a noisy call. Because transcription is fully offline, you can record and transcribe on a plane, in a basement, or anywhere else with no connectivity.
The second major feature is automatic speaker recognition and labeling. Using on-device diarization and a bundled neural voice model, Synopsule separates each speaker in the recording and automatically recognizes voices it has heard before. Name a voice once, and that person is automatically labeled in future recordings on the same device. You can correct a wrong guess, and the system learns from the correction. Voiceprints are stored entirely on-device and never leave, ensuring privacy. This feature is invaluable for recurring meetings or multi-session interviews where participants stay the same, saving you the time of manually labeling speakers every time.
The third major feature group covers the capture methods and integrations. On the Mac, Synopsule records your microphone and system audio in separate lanes using Apple's Core Audio taps, capturing both sides of Zoom, Google Meet, or Microsoft Teams calls without needing a bot or virtual driver. On the iPhone, it records the room through the microphone—perfect for in-person conversations, lectures, and voice notes. Exports are comprehensive: Word, Markdown, HTML, SRT, VTT, plain text, and PDF (Mac only). You can also send transcripts directly into Obsidian or Apple Notes in one tap. The built-in MCP server on Mac allows AI assistants like Claude Desktop, Codex, and ChatGPT to list, search, and read your transcripts directly, keeping everything local and read-only.
