AI Reader 1.3.0: Chinese and English interface

• Add Chinese and English interface selection in Settings. Preview changes immediately; Save settings applies and remembers the choice.
• Translate sidebar controls, history, source labels, settings, selection actions, and status messages.
• Preserve unsent questions, quotations, endpoint drafts, and active responses when switching languages. Existing messages, paper titles, and custom system prompts keep their original text.
• Remove the persistent reading hint below the paper permissions.
• Make the README entirely English while keeping its centered header and badges.

Existing installations keep Chinese until the language is changed in Settings. Interface language does not control the language of model answers; use the system prompt or your question for that.

Validation: TypeScript checks, 94 automated tests, and 187 native Zotero integration checks passed on macOS with Zotero 10.0.6. Native language checks used isolated memory storage and simulated responses.

Install zotero-ai-reader-1.3.0.xpi manually through Zotero’s add-on manager. Existing conversations and endpoint settings are preserved.
