Sider AI Sidebar
Sider AI is a browser sidebar for chatting with webpages, PDFs, videos, and multiple AI models while you browse.

Sider adds an AI sidebar to supported browsers. It can read webpages, documents, PDFs, and videos; answer questions; summarize and translate content; help write text; and generate images.
It also includes browser task automation and Sider Code, which changes webpage layouts or behavior from natural-language instructions and saves those changes for later visits. Free access is available, while paid plans provide more credits and a stronger cloud computer. The official pricing page did not display tier prices during this search.
