Harpa

HARPA AI is a Chrome browser extension for individuals and teams that combines multiple AI models with in-browser automation to speed up research, writing, and repetitive web tasks.

Key capabilities include:

• AI-assisted search agent with Quick and Deep Research modes that scans prioritized URLs, asks follow-up questions, and returns answers with source citations alongside engines like Google or Bing.
• Summaries and extraction for web pages, PDFs, and YouTube videos, plus ready-to-run commands for web scraping and structured data capture.
• Browser automation and monitors to track price drops, detect page changes, auto-refresh pages, run scheduled commands, and trigger webhooks that can turn sites into lightweight APIs.
• Workflow integrations with Make.com and ActivePieces to trigger automations from page changes or AI outputs.

Pricing: Freemium; premium plans start at $12/month (annual billing).

Notable for running automation locally in the browser for a privacy-focused setup, offering 100+ pre-built commands, and supporting multiple model options (including OpenAI GPT, Anthropic Claude, and Google Gemini) inside a single extension.
