Synopsule
On-device meeting transcripts
S$ 2.98 · In-App Purchases
Record on iPhone or Apple Watch and get on-device transcripts with speakers labeled. New language controls to transcribe speech as spoken or translate it to English
Synopsule turns your iPhone and Apple Watch into a private transcription studio. Record any conversation, see a live transcript as you talk, and when you stop, see who said what - all on your device.
Everything runs locally by default. Your audio never gets uploaded.
RECORD ON iPHONE OR APPLE WATCH
Tap record on iPhone for live transcription while you talk. Start from Apple Watch when your phone is not in hand, pause or resume, add markers, and send the saved recording to your paired iPhone for local processing.
TRANSCRIBES LOCALLY WITH WHISPER
OpenAI's open-source Whisper model runs entirely on your iPhone, optimized for Apple silicon. Choose a model size that fits your phone, from a fast compact model to a larger high-accuracy model. The download size is shown up front, and the model runs on-device once installed.
LABELS AND RECOGNIZES SPEAKERS
When a recording finishes, Synopsule figures out who said which line and assigns colored speaker labels on device. Name a voice once and it can recognize that person in later recordings. Rename "Speaker 1" to "Maria" and it propagates through the whole transcript. A speaker directory tracks people across recordings, and setting the expected speaker count can sharpen the result. Voiceprints stay on your iPhone.
NOTES AND FLAGS, ANCHORED IN TIME
Jot notes while you record or read. Each note is pinned to the moment, so tap to seek straight back, and your notes can feed into the AI summary as context. Drop a flag on anything worth finding again and give it a label.
OPTIONAL AI SUMMARIES, ON YOUR TERMS
Press Summarize, pick a template, and get a structured, speaker-aware recap with action items and open follow-ups. Then choose where it runs:
- Bring your own OpenAI, Anthropic, or Google Gemini key. Transcript text goes directly to that provider.
- On an Apple Intelligence-capable iPhone, summarize on-device when available.
- Or subscribe to Synopsule Pro and run summaries without managing your own key.
Synopsule names the destination and asks consent before any text leaves your phone. Your audio is never sent anywhere - only transcript text, only when you ask. You can revoke consent any time in Settings.
POWERFUL PLAYBACK AND EDITING
Tap any line to jump to that moment in the audio. The transcript follows along as it plays. Fix a word or reassign a speaker inline whenever you like.
SEARCH EVERYTHING
Full-text search runs across every transcript. Filter by who spoke using speaker: queries to jump straight to the right moment.
EXPORT ANYWHERE
Export to Markdown, Word (.docx), plain text, SRT and VTT subtitles, or interactive HTML. You can also send a transcript straight into Obsidian or Apple Notes in one tap. Choose what to include: timestamps, speaker labels, grouping by speaker, and the AI summary.
PRIVACY YOU CAN VERIFY
