AI Summarizer

AI Summarizer is a minimal Chrome extension for people who read a lot on the web and want the gist of a long article, documentation page or thread without scrolling. Click the extension icon, choose how you want the summary shaped, and it sends the page content to ChatGPT-3.5 and returns a condensed version in the side panel. The whole workflow takes a few seconds.

What separates it from generic summarizer extensions is the control it gives you. You can summarize only the text you have selected, which saves tokens and avoids noise when you only care about one paragraph. You can set a target summary length in words or characters, ask the AI to focus on specific keywords — for example the political career section of a biography — and choose between flowing prose and bullet points.

For pricing, the extension includes a free demo API key that allows a number of queries. Beyond that, you bring your own OpenAI API key, which is free to create and means you pay OpenAI directly for what you use rather than a subscription to the extension. The code is published on GitHub as a semi-open-source project, with a few files withheld because they could expose the shared public key. According to the developer, the extension has no access to your data and the only network request it makes is to ChatGPT.
