Your key is stored only in this browser (localStorage). Never share the file with your key inside it. Voice input needs Chrome or Edge. Best Cantonese voices: Microsoft Edge ("… Online (Natural)" voices) or a "Google" voice in Chrome; Mac users can also install a Premium voice in System Settings → Accessibility → Spoken Content. Models: a comma-separated list, tried in order; busy, rate-limited or unpaid models are skipped automatically. Premium models cost about HK$0.01–0.03 per conversation turn. Hong Kong-billed accounts cannot use OpenAI/Anthropic/Google models on OpenRouter; the Premium preset uses Qwen, Kimi and DeepSeek instead.
