Sider Code modifying a website with natural language prompts

Your browser, rewritten around your workflow.

Most websites are built for everyone. Sider Code lets you reshape them for the way you read, watch, research, and work.

Turn bright documents into a darker, calmer workspace that is easier on your eyes during long writing sessions.

How Sider Code changes a page

1
Describe the change

Tell Sider Code what you want in your own words.

2
Watch the page update

Sider Code understands the page structure, applies the change, and shows the updated page immediately.

3
Keep it for next time

Your customization is saved for that site, so it can apply automatically whenever you come back.

Why Sider Code is different

No scripts, no setup

You do not need to inspect the DOM, install userscripts, or manage per-site extensions.

More than blocking

Instead of only hiding elements, Sider Code can add actions, restructure content, and transform how a page works.

Changes that persist

Your customization can be remembered and applied the next time you visit the same site.

Understands page content

Sider Code combines page understanding with page modification, so it can summarize, extract, explain, and reshape in one flow.
