付费分析未识别到付费功能
The extension itself does not implement any billing, subscription, or payment gating. The 'premiumOnly: true' flags found in speech-iframe.js (lines 3002-3589) are metadata properties on ElevenLabs voice definitions. These flags mark certain text-to-speech voices as premium but are only descriptive metadata - the extension code does not check these flags to gate features or show upgrade prompts. No payment platform integrations (Stripe, etc.), no subscription logic, and no upgrade UI exist in the extension source code. The parent Read&Write product may have premium tiers, but this extension does not.

- No login UI or authentication flow exists in the extension. The extension works as a standalone OCR screenshot reader. The speech features reference a userName parameter in SpeechServerEngine settings (speech-iframe.js:1116, 1130), but this defaults to empty string and is used for speech server caching identification, not user authentication. The extension is a companion to Read&Write for Google Chrome, which may have its own auth, but this screenshot reader extension itself does not gate any functionality behind a login.
