What does Sider do?
Sider is a browser extension that adds an AI sidebar to Chrome, Edge, and other browsers. You can chat with multiple AI models (like GPT-4, Claude, Gemini) right from the side panel, summarize webpages or YouTube videos in seconds, translate pages into 50+ languages with side-by-side view, and get instant explanations on highlighted text. It also includes deep reading tools to ask questions and extract data from pages or uploaded files. All your chats, clips, and sources can be saved to Wisebase, a searchable AI knowledge base that grows as you browse.
The tool stands out because it lets you switch between top AI models with one click — or ask the same question to several models at once and compare answers. The translation preserves formatting and structure, not just raw text. The summarize feature gives you key takeaways and outlines you can copy or save. Wisebase goes beyond a simple chat history: you can upload PDFs, clip highlights from pages, record meetings for instant summaries, and even turn documents into presentation slides. It works across devices (Chrome, Edge, Mac, Windows, iOS, Android) with a single account.
Sider is best for anyone who spends a lot of time researching online — students, writers, professionals, or casual learners. Use it to quickly digest long articles, translate foreign language pages, gather notes for a project, or build a personal research library. The free tier handles daily tasks well, and paid plans unlock more model access and storage. If you often jump between tabs to use ChatGPT or other AI tools, Sider keeps everything in one sidebar, saving you clicks and context switches.
