Synopsule

Synopsule turns your iPhone into a private transcription studio. Record from your microphone and see a live transcript as you talk. When the recording wraps, see who said what — all on your device. Everything runs on your iPhone. Audio never leaves your phone. TRANSCRIBES LOCALLY WITH WHISPER OpenAI's open-source Whisper model runs entirely on your iPhone, optimized for Apple silicon. A live transcript appears while you talk. No internet required for transcription, and no audio is ever uploaded. LABELS SPEAKERS AUTOMATICALLY When the recording finishes, Synopsule diarizes the audio — figuring out who said which line — and assigns colored speaker labels. Rename "Speaker 1" to "Maria" once and it propagates everywhere. A speaker directory tracks people across all your recordings. MADE FOR REAL CONVERSATIONS In-person meetings, interviews, lectures, 1:1s, voice memos you actually want a transcript of — capture it through your iPhone's microphone and get a clean, labeled transcript without sending anything to a server. OPTIONAL AI SUMMARIES, ON YOUR TERMS Need a one-page summary, a checklist of action items, and a list of open follow-ups? Tap Summarize and pick your provider: • Bring your own OpenAI or Anthropic API key. Transcripts go directly to the provider you choose. • Or subscribe to Synopsule Pro and we'll run it through OpenAI for you. Your subscription works across iPhone and Mac. Either way, Synopsule asks for explicit consent and names the destination before any text leaves your phone. Audio never goes anywhere. You can revoke consent any time in Settings. POWERFUL PLAYBACK Scrub the timeline. Tap any line to jump to that moment. The transcript highlights the active line as audio plays back. EXPORT EVERYWHERE When you're done, export to whichever format fits: • Markdown — for notes apps and documentation • Plain text • PDF — share with anyone • SRT and VTT — for video subtitles Choose what to include: timestamps, speaker labels, grouping by speaker, and whether to attach the AI summary. PRIVACY YOU CAN VERIFY • Audio is captured and processed on your iPhone. It is never uploaded. • Transcripts live in your device's protected storage. Delete any recording whenever you want. • No analytics in the recording or transcription path. No tracking. SYNOPSULE PRO (OPTIONAL) Subscribe monthly ($4.99) or yearly ($39.99) to unlock cloud-hosted AI summaries without managing your own API key. One subscription covers both iPhone and Mac. Cancel any time in Settings → Your Apple ID → Subscriptions. — Requires iOS 17 or later. Optimized for Apple silicon.
