Never lose track of what was said or decided. Resonance records your meetings, transcribes every word, and uses AI to produce structured notes with summaries, key decisions, action items, and open questions: automatically. Whether you are running a one-on-one, a team standup, or a client call, Resonance turns spoken conversation into organized, searchable knowledge. RECORDING & TRANSCRIPTION Record meetings with live audio waveform visualization so you always know the mic is active. When the meeting ends, transcription begins immediately. Choose the transcription engine that fits your workflow: - WhisperKit: on-device, no internet required, supports speaker identification - Apple Speech: system-level on-device transcription - OpenAI Whisper: cloud transcription with high accuracy - Groq: fast cloud transcription - Custom endpoint: bring your own transcription service Speaker diarization via WhisperKit and SpeakerKit identifies who said what, so your notes reflect the actual conversation rather than a wall of anonymous text. AI-POWERED NOTES After transcription, Resonance enhances your notes into a structured document: - Summary of the meeting - Key decisions made - Action items with ownership - Discussion points covered - Open questions left unresolved Chat with AI about any meeting to ask follow-up questions, clarify details, or extract specific information without scrolling through the full transcript. POWERFUL SEARCH & ORGANIZATION Cross-meeting search lets you find any topic, name, or decision across your entire meeting history in seconds. Custom vocabulary teaches Resonance your domain — add project names, acronyms, technical terms, and people so transcription and notes use the right words from day one. CHOOSE YOUR AI BACKEND Resonance supports seven LLM providers for note enhancement: - Apple Foundation Models (fully on-device) - Ollama (local server, stays on your network) - Google Gemini - OpenRouter - OpenAI - Anthropic Claude - Custom endpoint No account is required. Configure only the providers you want to use. PRIVACY FIRST The developer collects zero data. No analytics, no advertising, no account required. Your recordings, transcripts, and notes live in the app's sandboxed storage on your device. API keys are stored in the iOS Keychain and are never logged or shared. The full on-device workflow — WhisperKit for transcription and Apple Foundation Models for note enhancement — requires no internet connection and sends nothing to any server. Cloud AI services are optional and off by default; they activate only when you add an API key. iCloud sync via CloudKit keeps your meeting history in sync across your own Apple devices using your personal Apple ID. PLATFORM SUPPORT Resonance runs on iPhone, iPad, Mac, and Apple Vision Pro. The interface uses Apple Liquid Glass design, available on iOS 26 and later. ---

No more stopping to type, cleaning up messy memos, or trying to remember where you saved an important note. Say what’s on your mind and keep moving. FROM VOICE TO ACTION Your thoughts don’t always arrive when you have time to write them down. Sayflow makes capturing them effortless. Record quick audio and Sayflow turns your speech into organized text. A simple thought can become a reminder, task, event, note, or shopping list automatically. Say things like: • “Tomorrow at 11, send the contract to Andrew” • “Call Andrew” • “Buy milk, eggs, bread, and watermelon” • “Idea: add a family mode” • “Doctor appointment Tuesday at 2 PM” Sayflow understands what you mean and helps put it in the right place.

Just speak naturally. Sayflow can transcribe your recording and turn your voice into useful text, helping you capture ideas before they disappear. It’s a simpler way to move from audio to action. NEVER FORGET WHAT MATTERS Turn spoken thoughts into a reminder with a date and time, save action items as a to-do, or capture an upcoming event before you forget it. Sayflow helps keep your everyday tasks together so important things don’t get buried across different apps. From errands and appointments to work ideas and personal plans, your second brain is always ready. CREATE NOTES, LISTS & IDEAS Capture a quick note while walking, driving, cooking, or whenever typing feels inconvenient. Planning groceries? Speak your shopping list and get an organized checklist.
