TabVoice

Real-time audio transcription and translation - 100% local AI

TabVoice transcribes audio from any browser tab in real time — YouTube videos, podcasts, webinars, online courses, and meetings — using AI that runs entirely on your computer. No audio leaves your machine. No cloud API. No account required. WHY TABVOICE? Most transcription tools send your audio to remote servers. That creates real risks: data breaches, subpoenas, training of third-party AI models, and compliance headaches under GDPR, LGPD, and other privacy laws. TabVoice takes a different approach. It runs OpenAI Whisper directly in your browser using WebGPU or WASM. Your audio is captured from the tab, transcribed locally, and stored in your browser. Nothing is uploaded. KEY FEATURES • Real-time transcription from any browser tab • 100% local processing — no audio sent to the cloud • Works offline after the first model download • Floating captions overlay on any webpage • Saved sessions with search, tags, and filters • Export transcriptions as .txt • Optional Pro license: history, search, export, and organization features WHO IS IT FOR? • Journalists and interviewers who need to protect sources • Lawyers, DPOs, and compliance professionals handling sensitive calls • Researchers working with confidential interviews • Therapists and healthcare professionals who need local, private notes • Students and professionals who want captions for videos and podcasts • Anyone who prefers to keep their audio data under their own control HOW IT WORKS 1. Open any tab with audio. 2. Click Start Capture in the TabVoice side panel. 3. The AI model (Whisper) transcribes the audio locally in your browser. 4. Read the transcript in the side panel or enable the floating overlay. 5. Stop when done. Your session is saved and searchable. PRIVACY BY DESIGN TabVoice does not collect, store, or transmit your audio or transcripts. The only network request is the first download of the AI model from Hugging Face, which is then cached locally in your browser. You can verify this behavior using Chrome Developer Tools — no outgoing audio requests during transcription. LIMITATIONS • Currently optimized for English audio. Support for more languages is coming. • The first use requires downloading an AI model (~40 MB). • Speaker labels (who said what) are not yet supported. • Word-level timestamp syncing with video is not yet available. • Requires a modern browser with WebGPU or WASM support. TabVoice is free to use for real-time transcription. A Pro license unlocks advanced history, search, export, and organization features.
