[Suggestion] Capacitor/Ionic cross-platform mobile voice note app with live transcription (TypeScript)

[deepgram-robot]

What to build

A Capacitor/Ionic mobile app (TypeScript) that records voice notes with native audio capture, streams audio to Deepgram for real-time transcription, displays live transcript text, and saves completed notes with transcription and Audio Intelligence analysis (topics, summary). Deploys to iOS, Android, and web from a single codebase.

Why this matters

Capacitor/Ionic is one of the most popular cross-platform mobile frameworks, especially for enterprise teams already invested in web technologies. Developers building voice-enabled mobile apps with Capacitor need a reference showing how to access native microphone APIs, stream audio over WebSocket, and handle the mobile-specific challenges (background audio, permission handling, battery-efficient streaming). No Deepgram example exists for this framework, leaving a gap between the Flutter example and the Expo/React Native example.

Suggested scope

• Framework: Capacitor 6+ with Ionic 8+ (Angular or React)
• Deepgram APIs: Streaming STT (Nova-3), Pre-recorded STT with Audio Intelligence (topics, summarization)
• Key patterns: Capacitor native audio plugin for microphone access, WebSocket streaming from mobile, real-time transcript display, offline-ready note storage (Capacitor Preferences or SQLite), permission handling (iOS/Android)
• Complexity: Medium — Capacitor plugin integration + WebSocket streaming + mobile UI

Acceptance criteria

• Runnable with minimal setup (clone, add API key, run)
• README explains the pattern clearly with Capacitor setup steps
• Uses current JS SDK version
• Works on iOS, Android, and web browser
• Handles microphone permission requests gracefully
• Saves transcribed notes locally for offline access
