OpenGPTs is a free, open-source Chrome extension that turns your browser side panel into an AI workstation. Instead of copying text into a separate ChatGPT tab, you keep a persistent assistant docked beside whatever page you are reading, so questions, summaries and translations stay in the flow of your work. The extension is positioned as a lightweight alternative to the many single-purpose ChatGPT plugins, bundling chat, summarisation, screenshot analysis and multi-model conversations in one place.
The feature set centres on a few practical shortcuts. A side-panel chat answers questions while you browse, instant screenshot analysis lets you capture any part of the screen and ask the model to interpret it, and text-selection summarisation condenses long articles in seconds. Multi-window conversations let you pose the same question to several GPTs side by side for different perspectives, while an internet-enhanced mode adds live search results to ground answers in current information rather than model memory alone. A web-automation 'operator' mode is listed as coming soon.
Because the project is open source, the extension is transparent about what it accesses. It requests webpage access to provide in-page assistance and clipboard access for quick summaries, and the developer states that browsing history and personal data are not collected. It is a third-party, community-maintained tool and is not affiliated with, endorsed by or produced by OpenAI.
Summarise long articles and course readings in the side panel, then ask follow-up questions on the same page.
Draft replies, explain jargon or rephrase paragraphs without leaving the document or site you are working in.
Capture a chart, table or dashboard and ask the assistant to describe trends or call out anomalies.
Pose the same question to multiple GPTs and compare viewpoints before deciding what to trust.
