Companies charge up to $30/month for meeting transcription services.
This costs $0 because there's no server. The AI runs on YOUR laptop using WebGPU.

90% accuracy. English only. No speaker labelling.
But honestly? ChatGPT doesn’t need a perfect transcript to generate an accurate meeting summary.

Flip the translate toggle in the header and pick a target language. Each committed English sentence is translated in real-time by Opus-MT (Helsinki-NLP), running locally in a Web Worker via Transformers.js — still no server, still offline.

• First-run download: ~75 MB per language pair, cached in the browser afterwards.
• Latency on a 2019 Intel MacBook Pro (CPU): typically 0.2–1s per sentence after warm-up. First sentence may take 2–3s.
• Supported targets: French, Spanish, German, Italian, Dutch, Portuguese, Russian, Chinese, Japanese, Arabic, Hindi, Turkish, Polish, Swedish, Greek.
• Changing the target language mid-meeting translates future sentences in the new language — previous translations are left as-is.
