Page Grep Autor: wugq.dev

PageGrep is a reading assistant that uses the OpenAI API to help you get more out of every web page — in any language.

Translate in place
Click the floating 译 button to translate all visible paragraphs directly on the page. Each paragraph gets a toggle so you can switch between the original and translated text at any time. Supports 17+ target languages.

Highlight what interests you
Describe topics you care about — "AI, climate policy, Formula 1" — and PageGrep uses AI to scan the page and highlight the most relevant elements in yellow. A sidebar panel shows why each item was matched. Use the ▲ / ▼ buttons to jump between matches.

Summarize any page
One click generates a structured summary of the page, grouped into sections with bullet points. Click any item in the summary to scroll directly to that part of the page.

Translate selected text
Select any text on a page and a floating "Translate" pill appears above the selection. Click it to see the translation in a tooltip — no need to open the panel or leave the page.

Block the panel on specific sites
Right-click the floating panel to hide it on the current site, or use the "Hide on this site" toggle in the sidebar. Blocked domains are listed in Settings and can be removed individually.

Designed to stay out of your way
The floating action panel is draggable. Drag it anywhere on screen, or drag it to the bottom trash zone to dismiss. Your API key and all preferences are stored locally — nothing leaves your browser except the page content you explicitly send to OpenAI.

Requirements
An OpenAI API key is required. gpt-4o-mini is recommended — fast, low cost (~$0.15 per million tokens), and accurate enough for everyday reading.
