Sider: All-in-One AI Sidebar for ChatGPT & Claude
Sider turns your browser into an AI powerhouse, blending ChatGPT, Claude, and Gemini into one sidebar for reading, writing, and chatting with any content.
Overview
Sider is a browser-based AI companion that lives right alongside your everyday web browsing, ready to help the instant you need it. Rather than juggling multiple AI tabs and subscriptions, Sider consolidates ChatGPT 3.5/4, Claude Instant/V2, and Gemini into a single, unified sidebar experience accessible from any webpage. Whether you're deep in research, drafting an email, or trying to make sense of a dense PDF, Sider's contextual assistant is just a click away.
What sets Sider apart is its versatility: it's not just a chatbot, but a full AI reading and writing suite. Users can chat with links, upload images for analysis, summarize lengthy YouTube videos, translate foreign text on the fly, or generate polished articles from scratch. Built-in tools like ChatPDF integration, an OCR-capable image reader, and a grammar checker mean you rarely need to leave your browser to get serious writing or research work done. The addition of group AI chat also lets users compare responses across multiple models simultaneously, making Sider a genuinely multi-model workspace rather than a single-AI tool.
From students cramming for exams to business professionals drafting reports, Sider adapts to a wide range of workflows. Its cross-platform reach—spanning Chrome, Edge, iOS, Android, macOS, and Windows—ensures your AI assistant is always within reach, no matter the device you're working on.
