Sometimes lags when loading long pages.

Generate a structured summary of the current page, useful for turning long articles into readable notes.
Select words, sentences or whole paragraphs and send them to the assistant, with support for multiple selections in a single conversation.
Keep your reading flow intact by handling queries inside the current tab instead of bouncing between windows.
The developer states that user data is not collected, sold or shared beyond what the extension needs to function.
Web AIChat is a small Chrome extension from the developer Fengzheng that adds an AI assistant layer to ordinary browsing. Instead of copying text into a separate chatbot, you open the Web AIChat panel on top of the page you are already viewing and ask it to summarize the article, explain a passage, or answer questions grounded in that page's content. The extension supports highlight-to-ask: you select a word, sentence or paragraph and push it into the chat, and you can make several selections in a row to build up context.
The extension is intentionally narrow in scope. It does not replace a full research workspace, and it is not a browser with AI built in — it is a summoned helper that keeps you from losing your reading position. Version 1.3.3 was published in November 2024, the listing reports around 115 users and no ratings yet, and it ships in English and Simplified Chinese. Use it when you want a fast summary or a quick clarification on a page without the friction of tab juggling.
Summarize long papers or blog posts and highlight key passages to ask follow-up questions while the source stays on screen.
Select a dense paragraph and ask for a plain-language explanation without breaking focus or opening another app.
Get quick answers about names, statistics or arguments in an article directly in the tab you already have open.
