SideGPT is a Chrome browser extension that brings AI-powered webpage analysis into the browser sidebar. While browsing any webpage, users can open the sidebar to summarize the current page, extract key points, or ask natural-language questions about the page content. It is positioned more like a “web reading assistant with built-in model API support” than a standalone large language model service.
According to the page, SideGPT supports three AI providers: OpenAI GPT-4, Google Gemini, and Anthropic Claude, allowing users to switch between different model providers. Typical features include instant webpage analysis, summaries, key takeaways, contextual Q&A, and follow-up clarification. It emphasizes the ability to understand webpage context, structure, and content, while integrating smoothly into the browsing workflow via a sidebar. It is suitable for research, news reading, and content discovery.
The page clearly states “Install Now - It's Free” and “100% Free to Use,” indicating that the extension itself is free. However, after installation, users need to add an API Key from OpenAI, Google, or Anthropic, so the actual cost depends on the pricing rules of those third-party model APIs. For users who already have API Keys, SideGPT offers good value; for ordinary users, however, applying for, configuring, and managing API Keys adds friction to getting started.
SideGPT’s privacy pitch is that API Keys are stored locally, conversations remain private, and the product follows privacy-first principles. It is delivered as a Chrome Web Store extension and integrates lightly with webpages through the sidebar. However, the main text does not disclose more specific data-handling details, such as whether full webpage content is uploaded, whether logs are retained, or how it handles Chinese UI support, Chinese webpage performance, long-page truncation, dynamic webpages, or logged-in pages. As a result, output quality still needs to be evaluated based on the actual type of webpage and the selected model.
Its advantages are that it is free, lightweight, supports multiple models, and allows users to ask questions directly about webpage content. It is especially suitable for researchers, news readers, students, and anyone who needs to digest long webpages quickly. The downsides are its reliance on external API Keys, limited service support information, less-than-fully-transparent costs, and potential uncertainty when accessing OpenAI, Google, or Anthropic APIs from mainland China. Chinese users should also pay attention to network connectivity, overseas API accounts, and payment issues. Depending on their needs, they may also consider alternatives such as Perplexity, Monica, Merlin, ChatGPT Sidebar, Kimi, or Doubao-style browser assistants.
