Hi HN, I’ve been working on SentiCall, an AI-powered call assistant that helps handle phone calls more effectively. It’s designed for people who deal with frequent meetings, international calls, or need real-time note-taking. What it does: 1. Real-time transcription of the other person’s speech 2. Instant translation for cross-language conversations 3. AI-generated smart reply suggestions you can send or have spoken for you 4. Post-call summaries to capture key points Why I built it: I often found myself struggling to both listen and take notes during calls, especially when dealing with different languages. Existing solutions were either too slow, too manual, or didn’t integrate well with real-time conversation. Stack: Flutter for cross-platform UI, Rust for backend. OpenAI for LLM, Google Cloud for STT/TTS. Currently on App Store. Would love feedback on: Features you think are missing for productivity-focused calls Any privacy/security concerns you’d like to see addressed https://sent
