What is HARPA AI?
HARPA AI splits the browser-AI market into two camps: sidebar chat toys, and actual automation. It belongs firmly to the second. Beyond the expected page-aware chatting — summarize a two-hour YouTube transcript, interrogate a PDF, draft replies in Gmail — HARPA ships a robotic-process engine that navigates pages, extracts structured data into tables, monitors competitor and price changes with alerts, and executes scheduled multi-step workflows. It connects to OpenAI, Anthropic, Google and local models, either through its CloudGPT tokens or your own API keys. The Chrome Web Store rating sits at 4.7 from roughly 3,200 ratings, and Product Hunt reviewers repeatedly frame it as the tool that replaced three other subscriptions. Pricing spans a free demo, $12–$19/month cloud plans, and a $240 lifetime X plan aimed at long-term users willing to bring their own keys.
Key Features
- AI Sidebar — Chat with GPT, Claude, Gemini and more, aware of the page you are on
- Page-Aware Commands — Summarize videos, PDFs, threads and articles instantly
- Web Monitoring — Track page and price changes with notifications
- Data Extraction — Scrape page content into structured tables and Sheets
- Automation Engine — Multi-step workflows with scheduling on paid tiers
- 100+ Prompt Library — Ready commands for SEO, LinkedIn, email and recruiting
- BYO Keys — Plug in your own API keys to control spend on any tier
Who is it for?
- SEO and content professionals living in research-heavy browser workflows
- Founders and marketers automating repetitive page tasks
- Recruiters and sales teams enriching LinkedIn profiles at speed
- Developers wanting an AI agent inside Chromium with BYO keys
Who is it NOT for?
- Firefox/Safari-only users — there is no port
- Mobile-first workers — desktop Chromium only
- Casual chatters who just want a sidebar bot (free tiers of rivals suffice)
- Teams needing SOC2-style vendor governance for AI usage
The Bottom Line
HARPA AI is the rare browser extension that graduates from gimmick to infrastructure: the monitoring and extraction automations genuinely replace manual work, and BYO keys mean your costs scale sensibly. Subscribe monthly first to confirm your workflows stick; if they do, the $240 X lifetime plan math wins after roughly 20 months — just respect that it is non-refundable and tokens are separate.
