Feel free to add AI Summary Helper to the list

[philffm]

Summary Helper, available as Chrome extension and universal bookmarklet is a versatile open source tool I built to enhance web browsing experience by providing AI-generated summaries of web content. By the summary being injected into the content itself it is also compatible e.g. with Send-to-Kindle or Webclipper tools. That way you can prepare articles to be read on the go - and supercharge them with a custom AI intro tailored to your needs.

The tool supports custom prompts for summaries + questions per article, allowing for tailored content suitable to specific languages, professions, or points of view.
