## Overview

ChatYY is a browser extension that positions itself as a 'personal smart steward' — one assistant that follows you across every website. Its entry point is deliberately simple: a keyboard shortcut opens the chat panel, selecting text triggers an explanation or translation, and a library of preset topics keeps conversations moving when you are unsure what to ask.

Beyond chat, it bundles the tasks people most often leave their browser to perform. YouTube videos get a one-click summary and outline; PDFs become conversational documents; Google and Bing results gain an AI answer layer; and a drawing studio turns text prompts into images in the style of Midjourney, Stable Diffusion or DALL·E. The developer also advertises frictionless sign-in with no account barriers, and Android and iOS support beyond the desktop extension.

ChatYY is built on GPT-4 and Claude 2, according to its listing, and is offered free with optional in-app purchases. It is a small independent project published by an individual developer under the name biganwang2, with version 1.3.17 released in May 2024 and a perfect but tiny 5.0-star rating from three reviews.

## Pricing & Plans

Free, with optional in-app purchases per the Chrome Web Store listing. No subscription price is published.

- **Quick summon chat box:** Press Ctrl+M or Cmd+M anywhere to summon the assistant, or highlight a word to get an instant explanation or translation.
- **YouTube summarization:** Generate a concise summary and outline of a long YouTube video so you can grasp the key points in seconds.
- **Chat with PDFs:** Open a PDF inside the extension and ask questions about its contents rather than reading every page.
- **AI drawing studio:** Turn a text prompt into an image, with workflows compared to Midjourney, Stable Diffusion and DALL·E by the developer.
