Voicely is a real-time structured thinking coach for mock interviews and high-pressure communication. It listens to your question, classifies the type, and coaches your answer with frameworks, filler tracking, and feedback.

What it does

• Real-time transcription via browser speech or Smallest streaming (PCM/Opus)
• Instant question-type detection with structured frameworks
• Practice mode flow: question → answer → quality feedback
• Filler word counter, input level meter, and latency tracking
• Demo prompts for rapid pitch mode

Getting Started

1) Install

npm install

2) Run

npm run dev
# or
yarn dev
# or
pnpm dev
# or

Open http://localhost:3000 to use the app.

Environment (optional)

For Smallest streaming:

NEXT_PUBLIC_SMALLEST_WS_URL=wss://api.smallest.ai/stt/stream

Demo flow (quick)

1. Click a demo prompt or ask a question.
2. The question locks and the framework appears.
3. Answer out loud and watch feedback update in real time.
