Grown-ups: run python3 serve.py in this folder and open http://localhost:8000/index-remote.html. serve.py adds the COOP/COEP headers the on-device SQLite database needs; opened any other way (file://, plain python3 -m http.server) the app still works but history is not saved. Voice uses the browser's speech service (in Chrome, audio is sent to Google). Opening this file directly (file://) works too, without saved history. Keep the app open in only one tab at a time.
