toktra

Translate English text on web pages into Simplified Chinese and render it inline below the original HTML.

toktra is a Chrome translation extension for readers who want fast English-to-Chinese inline translation without replacing the original page. It translates English webpages, selected text, and PDFs into Simplified Chinese, then renders the translation below the original content. The translation queue prioritizes the current viewport and the next two screens, so visible content appears first while lower content waits until the user scrolls. Key features: - Inline English-to-Chinese translation for webpages. - PDF translation through toktra's built-in PDF viewer, including local file:// PDFs when Chrome file URL access is enabled. - Manual mode, current-site auto mode, and global auto mode. - Selection translation popup for highlighted English text. - Local translation cache for faster repeat visits. - Optional AI webpage-structure analysis that sends only a lightweight page outline to the user-configured API. - User-configured OpenAI-compatible API endpoint, API key, and model. toktra keeps the original HTML visible and adds translations as separate inline blocks. It does not sell data, display ads, or include analytics tracking.
