What is Sider?
Sider AI is a browser extension that consolidates AI chat, summarization, translation, and research tools in a single side panel. It lets users switch among multiple AI models, ask the same question to each, and compare responses without leaving the page.
Web pages or YouTube videos can be summarized instantly, producing key takeaways, outlines, and quick answers that can be copied or saved. Highlighted text is explained on‑the‑fly, and pages can be translated into more than 50 languages with side‑by‑side preservation of structure and formatting.
Deep reading features allow users to query content, extract data, and clarify logic from any document. All interactions and useful snippets are stored in a searchable personal knowledge base called Wisebase, where chats, highlights, PDFs, and notes are indexed for later reference.
