Only checked chapters will be summarized. Chapter sizes shown before footnote/reference removal.
Parts will be saved as: …_part1.epub
Note: AI summarization is handled by a Cloudflare Worker backend. An API key is required for authentication.
Your API key is stored locally in your browser and never sent to anyone but your own worker. Keep it secret.
Select the AI model for summarization. Requests are sent to the worker backend.
Skip summarization if chapter/part has fewer characters than this. Use 0 to summarize all.
Max text length sent to AI for summarization. Longer text is truncated.
Prompts and model selection are saved in browser storage on this device.
