Read, automate, and customize work inside the browser

What is Sider AI extension?

Sider organizes its browser assistant around three functions: Chat, Hand, and Code. Chat explains and summarizes material such as webpages, PDFs, and YouTube videos. Hand performs multi-step work across websites, while Code changes the appearance or behavior of a page from a plain-language request. The common setting is the browser, where the user already has the source material, accounts, and work context needed to complete the task.

Use page context to ask better questions

Chat can summarize, translate, explain, and answer follow-up questions about the material being viewed. Ask about a specific claim, passage, or comparison instead of accepting a broad summary as a substitute for reading. For video or document work, check that the answer refers to the relevant source and preserves qualifications that might disappear in a shorter explanation.

Define the boundary of browser actions

Hand uses existing logged-in sessions to research, compare, extract, and organize information across real sites. Code can restyle or simplify a page and remember the change for later visits. Give these functions a clear outcome and inspect the result, especially when a task touches an account or when a personal page adjustment might hide information needed for another workflow.

Who is Sider AI extension for?

Useful for people whose research and routine work happen across many browser tabs, especially when they want assistance grounded in the current page and can clearly specify which information or actions belong in the task.

Before you get started

Review extension permissions and the scope of logged-in account access. Check source claims and automated results, and confirm that saved page changes do not obscure important controls or information during later visits.
