What is Sider?
Sider is an AI sidebar extension for Chrome, Edge and Safari that lets you chat with models from OpenAI, Anthropic, Google and others while you browse. It summarizes pages and PDFs, translates, rewrites text and answers questions about what is on screen.
Sider can compare answers from several models, read YouTube transcripts, explain highlighted text and help write in any text box. It also has web and mobile apps, plus tools for image editing and document translation.
The free plan gives a small number of daily credits. Paid plans add more credits for basic and advanced models and unlock heavier tools such as large PDF processing.
