What is Sider?
Sider is a browser extension located on the right side of the page. The official name for it is "Your Browser AI Agent". To put it in one sentence: one sidebar handles all your browser-related needs. Its capabilities are divided into three parts—use Chat to understand the current page, use Hand to run workflows for you on real websites, and use Code to modify the websites themselves. The boundaries between these three features correspond exactly to three different needs: understanding, taking action, and transforming.
Who is it for?
- People who read a large number of web pages, PDFs and videos in the browser every day and need to ask questions while reading.
- Marketers and researchers who often conduct data research, price comparison, and cross-site comparison.
- Want to customize a website to your liking without waiting for others' schedules.
- People who have installed several AI browser extensions and want to consolidate them into one entry point.
- Team members who need to continue using it across devices; the official website lists support for Chrome, Edge, Mac, Windows, iOS, and Android.

How to use Sider
- Start by getting familiar with just Chat: Select text on the page and ask direct questions to confirm it’s answering based on that specific page rather than giving general responses.
- Hand will operate the website using your logged-in session.
- First, assign tasks with low permissions to test, and expand the scope only after it works smoothly.
- Code modifies page styles and structures.
- practice on unimportant websites first and avoid modifying frequently used platforms right away.
- The official website features store honors such as Editor's Choice and Favorite of the Year, which can be used as a reference, but you should still check the permission scope and privacy policy on your own before installing it.
- There is a pricing page on the site and an educational discount is explained.
- it is not a zero-cost tool.
- Share one account across devices and confirm the form you will actually use before paying.
