Podcast Transcriber & Summarizer is a free, browser-based tool that transcribes spoken audio using the Whisper AI model, then extracts the most representative sentences into a summary. The summarizer is a classical word-frequency algorithm, not a neural/LLM summarization model — it picks real sentences from your transcript rather than generating new text.
Heads up: this uses a real AI speech recognition model (Whisper, Apache-2.0 licensed) running entirely in your browser via WebAssembly — nothing is uploaded to a server. The first use downloads and caches the model (~40MB); your browser only downloads it once.
