One Paragraph Chrome Extension

One Paragraph condenses any selected text, such as articles, research papers or blog posts, into a single summary paragraph using ChatGPT technology. A user selects text on a page and clicks a button to get the summary. The reviewer describes it as built for a quick read rather than in-depth analysis.

The extension itself is free, and Toolio found no paid plan on the Chrome Web Store in September 2026. However, it runs on the user's own OpenAI API key, so summarization costs are billed through a personal OpenAI account rather than covered by the extension.

Setup means signing up for an OpenAI account and pasting an API key into the extension's settings. After that, selecting text on any site and clicking a button returns a one-paragraph summary. The extension is very small, at roughly 17KB installed.

The reviewer notes that it requires a paid OpenAI API key rather than a built-in subscription, so costs accrue on the user's own account. It also has only one public rating, which is not much evidence of consistent output quality. Alex scored it 3.9 out of 5 on 5 Oct 2026.

Toolio lists MeetGPT - Chrome Extension, which transcribes and summarizes Google Meet sessions, QPrompt - Chrome Extension, a searchable library of ChatGPT prompts, My Ears Chrome Extension, which transcribes audio from Chrome tabs, and Trellis. One Paragraph itself sticks to summarizing selected text into a single paragraph.
