NoteCast — AI tab-audio note-taker

Capture a browser tab's audio, transcribe it locally with Whisper, and generate structured notes with a local Ollama model.

🛡️ Private AI Transcription. Your Data Never Leaves Your Device. NoteCast is a privacy-first AI transcription and note-taking extension. Transcribe browser audio, microphone input, and local audio or video files into searchable transcripts, summaries, action items, and structured notes—all processed locally on your own hardware. The difference is privacy. Unlike cloud-based transcription tools, NoteCast processes everything locally using AI models that you control. Your recordings and transcripts never have to leave your device. 🧠 100% Local AI Processing We bring the power of advanced AI directly to your machine using trusted open-source models: • Whisper – Runs locally for fast and accurate speech recognition from browser audio, microphones, windows/screens, and local media files. Works instantly, with no setup required. • Ollama – Generates AI-powered summaries, structured notes, key takeaways, decisions, and action items using a private language model that you control. Only needed for the notes step — transcription works on its own. Professional AI features without compromising your privacy or uploading sensitive data. 🚀 Key Features • Live Transcription – Capture real-time audio from your microphone, a browser tab, or any window/screen running outside the browser. • Browser Audio Capture – Transcribe meetings, webinars, videos, and other audio playing in your browser, with clickable timestamps that jump straight to that moment (deep-linking on YouTube). • Local Media Support – Transcribe audio and video files stored on your device — pick more than one at a time and they queue up and transcribe automatically. • Speaker Labels – Automatically distinguish who's speaking, with editable names that carry through to notes and exports. • AI Summaries & Insights – Automatically generate summaries, key takeaways, decisions, and action items, in a style you pick (meeting minutes, standup, webinar, interview, and more) or steer with your own instructions. • Chat with Your Transcripts – Ask questions about your transcripts — even very long ones — to quickly find important information and context. • Multi-Language Support – 28 interface languages and 28 transcription languages with auto-detect, plus translate-to-English for notes and transcripts. • History Management – Search, organize, and manage all of your transcripts in one place.
