| Description | Sider is a browser-extension AI assistant that overlays a sidebar on any website—Gmail, Google Docs, YouTube, PDFs, news, and social sites—so you can chat, summarize, translate, write, and research without switching tabs. It aggregates 20+ models (OpenAI GPT, Anthropic Claude, Google Gemini, DeepSeek, and xAI Grok) behind one subscription, aimed at students, freelancers, marketers, and knowledge workers who juggle reading, writing, and translation across the web. Its main differentiator is being an always-available in-page sidebar bundling many premium models plus a citing Deep Research agent, rather than a single-model standalone chatbot. | Gemini is Google's most capable AI model, designed to be multimodal from the ground up. With deep integration into Google Workspace, real-time search, and best-in-class multimodal understanding, Gemini powers Google's AI experiences. |
