HARPA AI

A sidebar that connects ChatGPT, Claude and Gemini to the page you are on to summarize, write, track prices and automate web tasks.

What it does

HARPA AI opens a sidebar in Chrome that connects chat models such as ChatGPT, Claude and Gemini to the page you are viewing, and adds commands for summarising, writing and web automation. It is aimed at researchers, marketers and online shoppers who repeat the same browser tasks.

Key features

  • Summarises long YouTube videos, PDFs and files from the sidebar
  • Runs a large set of predefined page-aware commands for common tasks
  • Monitors product prices so you can buy when they drop
  • Drafts and polishes emails and social media captions, hashtags and replies
  • Extracts data from images and pages and helps with spellchecking and translation

Use cases

  • Getting the key points of an hours-long video before deciding to watch it
  • Tracking the price of a product you plan to buy
  • Writing replies to messages on X, Reddit or Instagram in your own tone

Getting started

Press Alt+A or type a double slash on any tab to open the HARPA sidebar, then pick a command or type a request about the current page.

Good to know

Page content you work with is passed to the AI model you select, so avoid using it on sensitive pages. Automations and price tracking depend on how each site is built and may need adjusting.
