ChatGPT Sidebar is a browser-based AI sidebar for working with GPT, Claude, and Gemini inside a web browser. It is presented as a way to keep those models available in one place while staying in the current browsing session, rather than moving between separate platforms or tabs.
The product’s side panel supports switching between models and comparing responses in real time. It can answer questions about the article being read or the video being watched, with the panel described as reading the current page and returning information quickly. It also includes an integrated writing assistant for email correspondence, corporate reports, social media content, and technical documentation, and that writing workflow is described as working with Gmail, LinkedIn, and Twitter. In addition, the sidebar offers OCR and visual analysis for images and screenshots, extracting text and performing content analysis, translation, and structural transformation. The same interface is also described as handling translation of web content and selected text, along with summaries of articles, academic publications, and video content.
It is delivered as a Chrome add-on, with repeated prompts to add it to Chrome for free. The site also includes links for pricing, privacy policy, terms of use, blog, community, sign in, and help center. The tool is described as a browser side panel and a digital assistant for browsing, learning, researching, writing, and content analysis.
