ChatGPT + Claude sidebar for any browser tab — chat about the page, summarise, translate, draw.
Sider is a ChatGPT + Claude sidebar for any browser tab — chat about the page, summarise, translate, draw. Supports multiple AI models including ChatGPT, Claude, and Gemini within a single sidebar.
About Sider
Sider is a browser-extension AI sidebar that lets you chat about the current tab, summarize it, translate it, and generate images. It puts ChatGPT, Claude, and Gemini in one panel next to any page.
Where it differs is breadth in a single sidebar: multiple models to choose from, page-aware actions like summarizing, translating, and chatting about the current tab's content, plus AI image generation alongside the text tools.
It fits people who want quick AI help layered over whatever they are reading without switching apps, on a free daily allowance. It is a weaker fit for heavy use: the free tier limits messages and access to advanced models, and it is a browser extension with no standalone desktop or mobile app.
Against single-model assistants, Sider's angle is putting several models and page-aware actions in one browser sidebar.
