Question: Is there a browser extension that allows me to comment and engage with websites in real-time?

If you're looking for a browser extension to comment and interact with websites in real-time, Moot is a great choice. Moot lets you comment, chat and customize websites so you can encourage social interaction and discussion on a community level. It's got AI-based content moderation, a reputation system and support for multiple languages, so you can interact directly with others on the page.

Another interesting extension is Commented, which is geared for teams working on live projects. It's more focused on team communication and project management, but it offers real-time commenting and public commenting through a Chrome extension, so it can be useful for personal and professional use.

HARPA is another powerful tool that offers a variety of AI-powered features beyond commenting. With its instant answers, summarization and content generation abilities, it can dramatically improve your web browsing experience. Although it's more focused on automation and productivity, its real-time interaction with websites can be useful for interacting with content.

If you want to go full AI, QuickyAI turns any webpage into a ChatGPT interface so you can use the AI tool without leaving the page. With features like one-click content summarization and the ability to chat with any webpage, it can help you be more productive by making ChatGPT more accessible and convenient.
