GPT4Free Page Summarizer (Local Free API)

This userscript generates concise webpage summaries using a local GPT4Free instance (g4f), displayed in a sleek, collapsible sidebar. The backend AI is DeepSeek-R1. You can also summarize youtube videos (using transcripts).

The language detection is based on your browser settings.
