Sider Code

Sider Code is a new feature inside the Sider browser extension that lets you modify any website using natural language. Instead of accepting the web as designed for everyone, you describe what you want changed and Sider Code understands the page, writes the code, and applies the modification in real time.

The changes go beyond cosmetic tweaks. You can turn a comment section into a debate map, make technical terms explain themselves on hover, strip out content formats you never want to see, or rebuild a scattered thread into a focused article with its own navigation. Each modification is saved for your next visit and can be toggled on or off.

Sider Code runs inside the existing Sider extension, which already serves over 10 million users. The generated code is frozen once applied, and the team plans to add disruption detection for pages that update dynamically. For the first three days after launch, Sider Code is free for all users.
