About this extension
SummarizeThisPage creates clear, structured summaries of the current web page directly in the Firefox sidebar. Choose OpenAI or Google Gemini, select the output language, summary type, length, and writing style, then generate a formatted Markdown summary without leaving the page.
Available summary formats include main ideas, key numbers, TL;DR, and detailed summaries. The interface and generated content support English, French, German, and Italian.
The extension uses your own provider API key, stored locally in Firefox. Page content is sent directly to the selected provider only when you explicitly request a summary. SummarizeThisPage does not use an intermediary server and does not collect analytics.
