Synopsule

Cloud meeting recorders default to uploading your audio the moment a call ends — that’s how they do speaker diarization, summarization, and search. Synopsule inverts that assumption. It records your microphone and system audio in separate lanes on Mac, transcribes with Whisper running entirely on-device, labels each speaker using on-device voiceprints, and keeps the full audio file local so you can tap any transcript line and replay that moment. On iPhone the same codebase handles live in-room recording for interviews, lectures, and field notes. One $1.99 purchase covers both devices with no subscription required.

The defining feature is what never happens: no account sign-up, no audio upload, no bot joining your call. The vendor’s comparison table makes the contrast explicit — typical cloud notetakers discard the raw audio after processing; Synopsule retains it on your device. Speaker recognition works from on-device voiceprints, so returning participants get labeled automatically without their voice profiles leaving the machine. Summaries are gated behind an explicit opt-in, and even then only transcript text travels — not audio.

This fits teams doing user research, legal interviews, or executive calls where recording consent and data residency matter. It also fits anyone who has been locked out of their own notes because the app that held them changed pricing or shut down — exports land in Word, PDF, Markdown, HTML, SRT, VTT, Obsidian, or Apple Notes, in open formats any downstream tool can read. Where it breaks: there is no API, no calendar integration, no webhook, and no way to route completed transcripts into a shared workspace automatically. Teams that need notes delivered to Slack, Notion, or a CRM after every call will find themselves exporting manually every time — and at scale that friction compounds.
