Sider Code

Product Introduction

1. Definition: Sider Code is a browser-based AI Agent, specifically a web customization and automation tool, integrated into the Sider Chrome extension. It functions as a natural language interface to dynamically rewrite the Document Object Model (DOM), CSS, and behavior of any website in real-time.
2. Core Value Proposition: It exists to democratize web customization, allowing non-technical users to permanently alter any website's layout, content, and functionality to fit their personal workflow, eliminating dependency on developers, browser scripts, or multiple single-purpose extensions.

Main Features

1. Natural Language Web Reconstruction: Users describe desired changes in plain English (e.g., "summarize these comments," "add a dark mode," "remove the sidebar"). Sider Code's AI parses the instruction, analyzes the current page's structure and content, and executes the necessary code modifications directly in the browser. This leverages a combination of Large Language Model (LLM) comprehension and programmatic DOM manipulation.
2. Persistent, Site-Specific Customization: Unlike temporary browser DevTools edits, Sider Code saves the user's natural language instruction and the corresponding transformation logic. It associates this with the specific website domain, enabling the customization to be automatically re-applied on every subsequent visit, creating a personalized, persistent version of the web.
3. Context-Aware Content Transformation: The agent goes beyond simple element blocking. It understands semantic content, enabling complex operations like summarizing Reddit comment threads, restructuring X/Twitter threads into a linear article, extracting key data, or reformatting content for readability (e.g., on Wattpad or news sites). This combines real-time page analysis with generative and transformative AI actions.

Problems Solved

1. Pain Point: The one-size-fits-all design of most websites creates friction for individual user preferences and workflows, leading to distractions, inefficiency, and eye strain. Technical solutions (user scripts, browser extensions) require coding knowledge or managing numerous single-purpose tools.
2. Target Audience: Non-technical knowledge workers, researchers, students, avid readers, social media power users, and anyone who frequents websites with suboptimal layouts or distracting elements. It specifically targets users who want a tailored web experience but lack web development skills.
3. Use Cases: Creating a "Reader Mode" for any site; removing ads, recommendations, or Shorts shelves from YouTube; imposing dark mode on sites that lack it (like Google Docs); summarizing long forum debates (Hacker News, Reddit) for quicker comprehension; automating repetitive data extraction tasks from frequently visited pages.

Unique Advantages

1. Differentiation: Unlike ad-blockers or CSS injectors that only hide elements, Sider Code can add functionality and intelligently restructure content. Unlike bookmarklets or user scripts, it requires zero code and manages persistence automatically. It consolidates the functionality of dozens of niche browser extensions into one AI-powered interface.
2. Key Innovation: The integration of a real-time, instruction-following AI agent directly into the page modification pipeline. The core innovation is the seamless loop: natural language command -> AI understanding of page context -> generation of executable modification code -> application and persistent storage of the transformation. It turns the browser from a passive viewer into an programmable, adaptive interface.

Frequently Asked Questions (FAQ)

1. Is Sider Code free to use? Yes, the core Sider Code functionality for customizing websites with AI is available for free within the Sider browser extension, allowing users to describe and apply persistent changes at no cost.
2. How does Sider Code work technically? It uses an AI agent to interpret your natural language command, analyzes the live structure (DOM/HTML) of the webpage you are on, generates the appropriate JavaScript or CSS code to enact your request, injects and executes that code, and then saves the instruction to re-apply the same transformation automatically in the future.
3. Can Sider Code customize any website, including dynamic web apps? Yes, Sider Code is designed to work on any website or web application (like Gmail, Notion, or Facebook) because it operates by modifying the final rendered page in your browser, regardless of the underlying framework.
4. Is Sider Code safe and does it violate website terms of service? The tool runs locally in your browser to modify your personal view of a website; it does not alter the site's source code on its server. Use should align with the website's Terms of Service, and it is intended for personal productivity, not malicious alteration.
5. What happens if a website updates its design? If a major site redesign changes the underlying HTML structure that Sider Code's saved customization targets, the transformation may break or behave unexpectedly. In this case, you would need to issue a new, updated instruction to the AI agent to re-apply your desired customization to the new page layout.
