HARPA AI is great for people who work in Chrome and want an AI that can read the current page and run repeatable tasks on it; skip it if you only want a simple standalone chatbot or need a refund safety net. It opens as a sidebar on any page, where you can ask questions about the page, summarize videos and PDFs, draft text, or run saved commands.
Beyond chat, it can pull structured data from pages, watch pages or prices for changes, and fire webhooks to automation tools. You can use AI models either through HARPA's paid cloud connection, metered in Megatokens, through free-but-limited web sessions with ChatGPT, Claude or Gemini, or with your own API key. The vendor states it does not offer refunds, so use the free demo first.
Good for marketers, analysts, researchers and small teams who do repetitive web research and want it automated inside the browser. Not for people who want a plain chat app, who use browsers other than Chrome-based ones, or who need a refund guarantee or enterprise-grade support commitments.
Key features
Page-Aware AI Chat
Ask questions about the exact page you're viewing; HARPA reads and reasons over the page content in context rather than requiring copy-paste.
Automation Commands Library
100+ predefined commands cover tasks like SEO audits, email drafting, keyword extraction, and social media post writing, runnable with one click.
Web & Price Monitors
Watch any page for changes — such as price drops or competitor website updates — and receive notifications when they occur.
Data Extraction
Scrape structured data from web pages and export it directly to CSV or JSON for downstream use.
Workflow Triggers
Fire Zapier, Make.com, or n8n webhooks directly from a HARPA command to connect browser automation to broader workflows.
Multi-Model Cloud Connections
Route requests to GPT-5.x, Claude Sonnet, Gemini Pro, DeepSeek, Perplexity, Grok, or Llama from a single sidebar.
File & YouTube Summarization
Summarize PDFs, documents, and long YouTube videos into structured, actionable notes.
HARPA Grid API
Run custom HARPA commands and browser automations programmatically for more advanced, developer-driven use cases.

Pros and cons
Pros
- Goes beyond a chat sidebar: extraction, change monitors, scheduled commands and webhook triggers are built in.
- Free demo with web-session access lets you test real workflows before paying.
- Flexible model access: cloud models via Megatokens, web sessions, or your own API key.
- The Life plan is a one-time payment for users who bring their own keys.
- Pricing page gives rough per-Megatoken estimates (about 100 command runs or about 300 premium-model chats), which helps budgeting.
Cons
- Refunds are not offered; the vendor points to the demo instead.
- Megatokens are consumed faster by premium models and by output (output costs about 3x input), so budgeting takes effort.
- Scheduling and advanced automation are not in the cheapest plan.
- The pricing page mixes plan names (Everyone/Pros/Life vs S1/S2/X) and quotes different top-up discounts, so read carefully before buying.
- Free web-session connections depend on the third party's login and are rate limited.
