Rivea

AI reading companion — bilingual translation, contextual chat, and note export with your own API key.

Rivea is an AI reading companion for people who read deeply across languages. It helps you read web pages and PDFs with paragraph-level translation, contextual chat, vocabulary capture, note export, and reading history. You can connect your own compatible AI service and choose the setup that fits your workflow. Core capabilities: - Translate paragraphs and selected text while keeping the original context visible. - Ask questions about a paragraph, selection, article, or PDF section while reading. - Save vocabulary with context for later review. - Export notes to Obsidian, Bear, or Notion. - View reading history and basic reading stats inside the extension. - Discover similar articles and related reading based on what you are reading. - Choose between cloud-powered recommendations or recommendations that run locally on your device. - Optionally sync selected local data to your own cloud storage with end-to-end encryption. Supported reading surfaces: - Standard web pages - PDF documents opened in the browser Why Rivea is different: - Use your own AI service key instead of routing requests through a Rivea server. - Translation and chat requests are sent directly to the AI service you choose. - Your saved vocabulary, reading history, and recommendation data stay on your device unless you explicitly enable export or sync. - Similar-content suggestions can also run locally for users who prefer not to send article text to a cloud service for recommendations.
