co-reader is a Chrome add-on designed to improve reading comprehension by providing paragraph-level summaries and highlights. It offers a unique side panel that displays one-sentence summaries for each paragraph of any article, helping users to better grasp the main ideas and key phrases while reading. This tool is particularly useful for those who want to engage more deeply with long-form content or blog posts.

The add-on features synchronized scrolling between the article and the summary panel, ensuring that users can easily navigate through the text. Additionally, co-reader allows for cross-referencing between related paragraphs, enriching the reading experience. Users can also choose from various LLM providers for processing, ensuring that their data remains private and secure, as no personal information is collected.
