SyncBrief turns meeting audio into a brief you can act on: a searchable transcript and a structured summary with a timeline, decisions and action items. It runs on your own AI provider key, or entirely on-device. No account, no servers of ours, nothing tracked. RECORD ANYWHERE • One tap on iPhone or Apple Watch. Recording keeps going with the phone locked. • A Control Center button and a watch complication start a recording without opening the app. • Watch recordings arrive in your iPhone library on their own over Watch Connectivity. BRING AUDIO IN FROM ANYWHERE • The share sheet from any app, including recordings made with iOS call recording. • The Files app, iCloud Drive, and USB voice recorders through an adapter. • Importing is free and contacts nobody. Transcription runs only when you ask for it. SUMMARIES WITH RECEIPTS • A structured brief per meeting: timeline of topics, decisions, action items with owners, open questions. • Every timestamp comes from the transcript, never invented by the model, and is checked against the length of the recording. • Tap any line to jump the audio to that moment. • Everything the AI writes is labeled as AI-generated and is yours to edit. Your edits survive regeneration. WHO SAID WHAT • Speaker labels on every line, from your transcription provider or worked out on-device when the provider cannot tell voices apart. • Rename "Speaker 1" to a real name once and it applies across the meeting. MIND MAP • Each meeting drawn as a map: topics around the center, decisions and action items on the branches. Tap a node to hear that moment. A LIBRARY YOU CAN SEARCH • Everything lives in an encrypted database on your device. • Instant full-text search across transcripts, titles, speakers, tags and summaries. • Export any meeting to Markdown, PDF, plain text or JSON. • Send your library straight to a Mac running SyncBrief, device to device over the local network. YOUR KEYS, YOUR CHOICE OF AI Transcribe with OpenAI, Deepgram, AssemblyAI, Apple's on-device speech, or Whisper running locally on your device. Summarize with Anthropic's Claude, OpenAI, or Apple's on-device model. Keys are stored in the iOS Keychain, never in the library and never in an export, and traffic goes only to the provider you picked. FULLY OFFLINE IS A REAL OPTION Choose Whisper or Apple for transcription and Apple's on-device model for summarising, and a meeting is processed from start to finish with no network at all. Nothing leaves the device. (Whisper downloads its model once, the first time you select it.)
